RESUMO
Introduction: Children requiring venoarterial (VA) extracorporeal membrane oxygenation for long durations may have increased risk of complications compared to venovenous (VV) ECMO. The purpose of this study was to evaluate the feasibility and safety of conversion from VA to VV ECMO. Method(s): This is a retrospective review of all children requiring VA ECMO who underwent conversion to VV ECMO at a single institution, from 2015- 2022. Indications for and methods of conversion were examined as well as adverse events including re-operation, ischemic complications, renal failure, and mortality. Descriptive statistics were calculated. Result(s): Of 422 pediatric patients on initial VA ECMO, only three children (0.7%) underwent conversion from VA to VV support, ages 10-19: for hypoxic respiratory failure due to COVID19, for cardiac dysfunction following orthotopic heart transplant, and for sepsis with associated left ventricular dysfunction. The indications for conversion were bleeding from cannulation site (n=2, 66%) and an anticipated prolonged ECMO run (n=1, 33%). For all three patients, the method of conversion was cutdown with femoral arterial repair followed by placement of additional jugular venous cannulas (n=2, 66%) or insertion of a singular jugular bicaval venous cannula with removal of the femoral cannulas (n=1, 33%). The median time on VA ECMO prior to conversion was 8 days (range 4-54 days). All 3 patients were managed with renal replacement therapy with 1 patient (33%) progressing to long term dialysis. There were no significant ischemic limb complications although one (33%) patient developed a femoral artery pseudoaneurysm that required re-operation. Two of the three patients (66%) were able to be decannulated at a median of 23.5 days (range 8-39 days) following conversion to VV ECMO and survived to discharge. The other patient was unable to be decannulated after successful conversion and care was withdrawn. Conclusion(s): Based on this small pilot study, conversion to VV ECMO from initial femoral VA ECMO cannulation is safe and feasible. Indications for conversion include coagulopathy and need for extended ECMO run after recovery of cardiac function.
RESUMO
Introduction: Primary Pancreatic Lymphoma (PPL) is the exceedingly rare instance of extranodal Non-Hodgkin's Lymphoma developing mainly in the pancreas.We report a diagnostically challenging case of a patient presenting with a rapidly growing pancreatic mass, found to have PPL. Case Description/Methods: A 48-year-old female with past history of tobacco use presented with several months of cramping abdominal pain following COVID-19 infection. She denied weight loss, fevers, or night sweats. Her physical exam, CBC, CMP, lipase, LDH, and CA 19-9 were unremarkable. An abdominal ultrasound revealed a 2.8 x 1.9 x 3 cm cystic mass of the pancreatic head, most congruent with a pseudocyst. Worsening abdominal pain prompted repeat ultrasound one month later, which showed a doubling in size. Endoscopic ultrasound (EUS) with fine needle aspiration of the cystic mass and surrounding lymph nodes yielded cystic contents and reactive lymphadenopathy. Two months later, her abdominal pain worsened and repeat imaging showed further doubling in size with encasement of the celiac plexus. A second FNA performed via EUS redemonstrated cystic contents. An ultrasound-guided core needle biopsy of the mass revealed necrotic CD301 diffuse large B cell lymphoma (DLBCL). PET scan was suggestive of stage IV PPL (Figure). Imaging also identified an inguinal lymph node that returned as CD101 BCL61 high grade follicular lymphoma, which was thought to be a distinct lesion. She was started on R-CHOP. Her clinical course was complicated by the formation and subsequent rupture of a splenic artery pseudoaneurysm, gastrointestinal bleeding, anuric kidney injury, and intestinal ischemia. She ultimately transitioned to comfort care. Discussion(s): Primary pancreatic lymphoma comprises 0.6% of extranodal lymphomas and 0.2% of primary pancreatic tumors. The clinical presentation is often vague and includes abdominal pain, B symptoms, jaundice, or bowel obstruction. The diagnostic criteria according to the WHO requires that the (1) majority of tumor burden be localized to the pancreas and (2) existing nearby and distant lymph node involvement should be secondary to pancreatic presentation. A biopsy is required to diagnose PPL, which is histologically most often DLBCL. Our case highlights the challenges associated with diagnosing PPL despite two EUS with FNA. Although rare, one should proceed with a high index of suspicion for PPL in any patient presenting with a rapidly enlarging pancreatic mass.
RESUMO
Introduction: The mortality rate of patients hospitalized with a lower gastrointestinal bleed has been reported at 1.1% in the United States from 2005 to 2014. Pseudoaneurysms, typically associated with pancreatitis, have been described in case reports as a rare condition with a small subset presenting as gastrointestinal bleeding. Our study describes a rare case of recurrent lower gastrointestinal bleeding diagnosed as a pseudoaneurysm by endoscopy and angiography. Case Description/Methods: A 38-year-old male presented to our facility from a long-term care facility with hematochezia and blood clots per gastrostomy-jejunostomy. He had recently been hospitalized for severe coronavirus disease 2019 with a complicated hospital course in the intensive care unit including necrotizing pancreatitis with an abdominal drain, multiple secondary infections, tracheostomy, and percutaneous endoscopic gastrostomy-jejunostomy. On previous hospitalization, he was found to have a small pseudoaneurysm of the gastroduodenal artery and received embolization of the gastroduodenal and gastroepiploic arteries at that time. During transport to our hospital, he was noted to have tachycardia, hypotension requiring norepinephrine, and was transfused one unit of red blood cells. Hemoglobin at this time was 7.5 g/dl after transfusion. Esophagogastroduodenoscopy was completed and showed a gastrojejunostomy tube in the expected location but was noted to be tight to the mucosa, which was pale in appearance. Flexible sigmoidoscopy revealed localized areas of edematous and erythematous mucosa with some associated oozing throughout the sigmoid colon. Repeat evaluation was completed one week later due to recurrent hematochezia. Colonoscopy was performed with identification of an apparent fistulous tract in the sigmoid colon located at 35 cm. Computed tomography angiography localized a pseudoaneurysm arising from the marginal artery of Drummond just proximal to its anastomosis with the ascending branch of the left colic artery and was successfully embolized. Discussion(s): Pseudoaneurysms, such as the one described in this case, have been shown to be associated with pancreatitis and can result if a pseudocyst involves adjacent vasculature. Gastrointestinal bleeding is a rare presentation of this condition. However, this case highlights the importance of repeat colonoscopy and angiography in the setting of a lower gastrointestinal bleed of unknown etiology.
RESUMO
Background: Spondyloptosis is caused by high force trauma. The vast majority of cases occur in the sagittal plane and at transition points where ridged sections meet more flexible regions. Lateral thoracic spondyloptosis is extremely rare and there is no current consensus on the optimal treatment plan. Case Description: Here we present a case of a previously physically healthy 24-year-old polytrauma patient after he was struck as a pedestrian by a motor vehicle. Of note the patient was found to have lateral spondyloptosis between T9-10 with complete spinal cord transection. The patient also sustained multi-ligamentous left knee injury, pelvic fractures, open comminuted left tibia and fibular fracture, lacerated liver, bilateral renal lacerations, ischemic bowel, and an aortic arch pseudoaneurysm. Conclusion(s): Lateral thoracic spondyloptosis is a devastating injury with an extreme rate of persistent neurologic deficits. There is no unanimously accepted treatment because of the rarity if the injury and the poor outcomes that patients face. Additionally, patients who experience high level trauma often develop severe psychiatric illness, and the importance of identifying risk factors and implementing care early may improve patient outcomes.Copyright © AME Medical Journal.
RESUMO
Pulmonary artery pseudoaneurysms (PAPs) are uncommon entities consisting of contained rupture of the pulmonary artery and are a potentially fatal cause of hemoptysis. We describe two index cases of left lower lobe PAPs and arterial ectasia post-COVID-19 pneumonitis and their endovascular treatment with Amplatzer vascular plug, coils, and glue.Copyright © 2022.

RESUMO
Pseudoaneurysm of the thoracic aorta is a rare condition associated with high mortality. We present a case of a patient who developed a huge pseudoaneurysm 10 years after the Bentall procedure and one aortocoronary bypass while simultaneously being COVID-19 positive. After treating pneumonia, the surgery was successfully performed with suturing two defects in the aortic conduit. It is a unique case report where the patient survived two life-threatening conditions.Copyright © 2023, CKS.
RESUMO
Introduction: Hughes-Stovin syndrome (HSS) is a systemic vasculitis characterized by pulmonary artery aneurysms (PAA) and widespread venous and arterial thrombosis. Fatalities in HSS resulted from unforeseeable fatal suffocating hemoptysis. It is critical to early detect pulmonary involvement to take timely measures against inevitable serious life-threatening complications. Case presentation: A 27 year old Filipino male patient presented to the emergency department with an acute attack of massive hemoptysis. The markers of inflammation were elevated with anemia and a normal coagulation profile. The patient had bilateral lower limb edema with tender calf muscles. Color Doppler ultrasound revealed bilateral deep vein thrombosis. Importantly, an urgent computerized tomography pulmonary angiography (CTPA) revealed bilateral large PAAs which matched the pattern of pseudoaneurysms described by the HSS international study group (HSSISG). There was no history of iridocyclitis, recurrent oral or genital ulcers. Accordingly, the patient was diagnosed with HSS. The patient received intravenous pulse methylprednisolone (1 g/3 days), then oral prednisone (1 mg/kg/d/3 months), and monthly pulse cyclophosphamide (1 g) for three months. The patient remained symptom-free, yet on the third pulse of cyclophosphamide;he patient contracted corona virus disease-2019 (COVID-19) infection and died three weeks later from a fatal episode of massive hemoptysis. The case was discussed and the recent literature was reviewed relative to fatal hemoptysis associated with pulmonary artery pseudoaneurysms (PAPs) pattern in HSS Conclusion(s): HSS presenting with massive hemoptysis could be lifethreatening and the PAPs are considered a double edged sword. Detailed description of such rare cases is warranted for optimum future management.Copyright © 2023
RESUMO
SESSION TITLE: COVID-19 Co-Infections SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/19/2022 12:45 pm - 1:45 pm INTRODUCTION: PAP is a rare entity that can occur secondary to infection, malignancy, or trauma. Mucormycosis in the setting of Covid-19 pneumonia has been increasingly recognized but PAP has only recently been reported in this setting. CASE PRESENTATION: A 44 year-old man with type 2 diabetes, non-ischemic cardiomyopathy, hypothyroidism, and ulcerative colitis presented with dyspnea and cough in July 2021. He was diagnosed with Covid-19 pneumonia and initially treated with molnupiravir. Eight days later he presented to the emergency room with worsening dyspnea, hypoxemia and diabetic ketoacidosis. He required 3L of oxygen and was intubated for airway protection. CT chest revealed mild bilateral patchy opacities and dexamethasone was started. Unfortunately, persistent fevers and worsening respiratory status ensued and repeat chest CT on hospital day (HD) 8 showed a new large left upper lobe (LUL) cavitary lesion. Cultures ultimately grew Rhizopus microsporus and he was started on amphotericin then isavuconazole after acute kidney injury developed. Dexamethasone was discontinued and interval imaging after ten days showed dramatic growth of the cavitary lesion (9 x 6 x 3 cm) with new extension through the chest wall, infiltrating the intercostal spaces and pectoralis muscle. Due to ventilator dependency a tracheostomy was performed on HD 24. Despite anti-fungal therapy the cavitary lesion persisted, with evidence of osseous destruction of the third and fourth ribs, as well as new fluid collections within the cavity and hilar extension. On HD 46 he was transferred to our institution for Thoracic Surgery and Interventional Radiology (IR) evaluations. Percutaneous drain placement followed by pneumonectomy vs. staged cavernostomy was considered;however, on HD 50, the patient suddenly developed massive hemoptysis. CTA of the chest showed a 1.6 x 1.5 cm PAP with active hemorrhage from the LUL anterior segmental artery with dispersion into the cavity. Urgent coil and glue embolization was successfully performed by IR. Ultimately, thoracic surgical intervention was deemed too high risk and thus he was medically managed with a regimen of isavuconazole, amphotericin, and terbinafine. Hemoptysis did not recur and he was eventually discharged from the hospital and liberated from both mechanical ventilation and tracheostomy. Chest CT 6 months from the initial diagnosis has shown stable to mildly decreased size of the cavitary lesion. DISCUSSION: This is the first case to our knowledge of PAP as a complication of Covid-19 and Mucor superinfection in the United States. Five cases of this combination have been recently reported in other countries. Risk factors for Mucor infection after Covid appear to be uncontrolled diabetes, DKA, and steroid administration. CONCLUSIONS: A high index of suspicion should be maintained in patients with these risk factors, as PAP can present as massive hemoptysis and is often fatal.

RESUMO
Objectives: To evaluate the surgical volume, surgical outcomes, and the evolving role of gynecologic oncologists in peripartum hysterectomies (PPH). Methods: We conducted an IRB-approved retrospective chart review of PPH cases performed at our institution from June 1, 2014, to June 30, 2021. Clinical-pathologic information was ed into a REDCap database. All analyses were conducted using STATA 17. Results: A total of 109 cases were performed over the 7-year period. Gynecologic oncologists (GYO) involvement in the cases increased from 33% in 2014 to 80% in 2021. The mean age was 36 (range: 23-47) years. Most patients were White (81/109, 74.3%), and the median BMI was 30.7 (range: 21-57) kg/m2. Surgical indications included placenta accreta syndrome (PAS) in 84 (77%) cases, uterine atony in ten (9.2%), uterine rupture in three (2.8%), malignancy in five (4.6%), and hemorrhage other than atony in seven cases (6.4%). Intraoperative complications included bladder injury (or intentional dissection) in eight (7.3%), ureter injury in four (3.7%), vascular injury in three (2.8%), and femoral pseudoaneurysm in one (0.9%) of the cases. Postoperative complications included urinary tract infection in 11 (10.1%), nerve injury in one (0.9%), surgical site infection in 13 (11.2%), and venous thromboembolism in five (4.6%) cases. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) usage started in 2019 with one case followed by six cases in 2020 (31.6%) and 3/16 cases in the first half of 2020 (15.8%). A higher REBOA usage in 2020 corresponded with blood products shortages during the COVID crisis.[Formula presented] Conclusions: Overall volume and complexity of peripartum hysterectomy are increasing. This trend is likely driven by an increased incidence of placenta accreta syndrome cases. Gynecologic oncologists are increasingly delegated as primary surgeons in many institutions. Fellowship training programs should strongly consider training in peripartum hysterectomy for trainees.
RESUMO
Case series: Extracorporeal membrane oxygenation (ECMO) use for severe acute respiratory distress syndrome due to coronavirus disease 2019 (COVID-19) patients has increased during the second wave of the pandemic. However, there are many complications associated with the management of ECMO in critically ill COVID- 19 patients. We report a case series of challenges and strategies for managing critically ill COVID-19 patients on ECMO support for severe ARDS. Seven COVID-19 patients required VV ECMO of which three were women and four were men of median age of 43 years. Among seven, three cases (42%) recovered. We experienced multiple challenges and complications in the management of the patients, being a non-ECMO centre with limited resources, in heavy workload during the second wave of the pandemic. All the patients required multiple invasive procedures like placement of invasive lines, frequent bronchoscopies for bronchial toileting. Displacement of both ECMO cannulas required repositioning under ultrasound guidance, four patients underwent percutaneous tracheostomy on ECMO. Three patients had ECMO-oxygenator failure that required the exchange of a new ECMO circuit. ACT was monitored for the management of anticoagulation. A challenging task is to achieve a balance between bleeding and thrombotic events, for which anticoagulation had to be stopped for the acceptable ACT, required transfusion of multiple blood products for correcting coagulopathy. One patient developed HIT antibodies and managed with bivalirudin for the management of anticoagulation which was challenging in titrating the drug dose and ACT. Two patients had an intracranial haemorrhage on ECMO support, managed conservatively despite anticoagulation. Pseudoaneurysm of femoral vein diagnosed and managed with ultrasound-guided thrombin injection. Four patients got decannulated from ECMO. One patient had unexplained severe haemolysis immediately after initiation of ECMO, unfortunately, he could not recover. Management of VV ECMO in resource-limited, non-ECMO centre in a pandemic is challenging. Mortality depends on various factors, despite expertise, advanced critical care management in COVID- 19 ARDS and ECMO. Increased use of VV ECMO during the second wave of pandemic reported significant changes in strategies for management of challenges, though further studies are still required for the best outcome.
RESUMO
Introduction: It is rare for pulmonary SCLC to present as a cavitating lesion unlike non-small-cell-cancer (NSCLC). Hence, if a cavitating lesion is found with histo-pathology showing SCLC, it is important to rule out alternate diagnosis e.g., infection [1]. Case: We present the case of a 41-year-old-male of Bangladeshorigin. He was referred on 2ww-pathway to UHL Glenfield hospital lung cancer team for haemoptysis. Clinical assessment (05/12/2019) revealed that he had 4kg weight loss/haemoptysis/anorexia/fatigue. He was a current smoker (10 pack-years) with no significant past/ family history. He worked in a restaurant. Clinical examination was unremarkable. Chest x-ray showed left-hilar-mass. CT scan revealed 3.2cm mass with peripheral cavitation and mild focal enhancement without calcification/mediastinal-lymphadenopathy. Differentials included cancer/rheumatoid arthritis/infection. Bloods including ANCA/ANA/rheumatoid factor and bronchial-washings microbiology/cytology were unremarkable. He was given antibiotics. He did not attend subsequent 2 out-patient-appointments. Repeat CT scan (March 2020) showed growing lesion with focally dilated vessel. CT-guided biopsy was advised but he declined it due to COVID19 pandemic. In May 2020, he agreed to undergo CT-guided biopsy. However, pre-procedure CT scan showed possible pseudoaneurysm. CT-guided biopsy was deemed high-risk and not attempted. Lung cancer MDT advised lobectomy given diagnostic dilemma. Patient declined surgery. CT in November 2020 showed progressive lesion. Patient still was not keen for surgery. He was admitted in June 2021 with haemoptysis. CT scan showed progressive cavitating disease with necrotic left hilar/mediastinal lymph nodes. He underwent EBUS-TBNA that confirmed SCLC. Given cavitating lesion and long history, left lower lobe lesion was deemed unlikely to be due to SCLC. He was referred to infectious disease (ID) clinic. Blood parasitology screen revealed positive Hydatid ELISA. He did not attend subsequent outpatient appointments in Oncology/ID clinics and has been discharged. Learning points: There were two pathologies: hydatid cyst (Fig. 1a);SCLC developed between November 2020 and June 2021 (Fig. 1b). 1) To look for cause of a cavitating lesion even if SCLC is diagnosed. 2) To consider hydatidcyst in lung-cavity differentials.(Figure Presented) Fig. 1
RESUMO
Background: We report a rare case of solitary peripheral pulmonary artery aneurysm in a patient who was evaluated for haemoptysis. Incidentally, his total antibodies were positive for Coronavirus 2019 infection. Patient underwent right lower lobectomy uneventfully. Peripheral pulmonary artery aneurysms arising from segmental or intrapulmonary branches are extremely rare. Untreated, the majority end fatally due to sudden rupture and exsanguination. The purpose of this article is to report our rare case and review the pertinent literature. Case Study: A 40-year-old man presented with an episode of haemoptysis. He had a history of intermittent mild grade fever, cough and dyspnea lasting for a month. He had no history of haemoptysis in the past. He had no pre-existing medical conditions or Coronavirus 2019 (COVID-19) infection. His clinical examination was unremarkable. Blood investigations were within normal limits. Reverse transcription polymerase chain reaction test was negative for COVID-19 infection, but his total antibodies test was elevated -117 (biologicalreference range <1.0). 2D Echocardiography was normal. Chest radiography showed a solitary pulmonary lesion in the right lower lung zone [Figure 1a].A computed tomography of the chest plain and contrast confirmed the presence of a 3.7 cm-3.6 cm, well-defined, circumscribed and densely enhancing lesion in apicoposterior segment of right lower lobe. It is seen along the course of descending branch of the right pulmonary artery. Areas of consolidation are also seen in apicoposterior segment. Postcontrast study shows heterogenous enhancement of this lesion suggestive of an aneurysm. The rest of lung parenchyma was normal [Figure 1b and c].The diagnosis of a solitary peripheral pulmonary artery aneurysm (PAA) was considered and right lower lobectomy was performed through posterolateral thoracotomy. Discussion: The estimated incidence of PAA is 1 in 14 000 autopsies, and these lesions can be central aneurysms and peripheral aneurysm. An aneurysm can be true or pseudo aneurysm. In this patient, an aneurysm is a true aneurysm and origin may be idiopathic or post-inflammatory with superadded fungal infection in thrombus, post-COVID-19 infection. Long-term follow up is required to observe the future course Conclusion: True solitary peripheral PAA is an extremely rare entity. A high degree of suspicion is needed for diagnosing PAAs on imaging. Intervention is mandatory as soon as the diagnosis is made, to prevent rupture and death. PAA has been managed most often by lobectomy but occasionally by pulmonary artery repair or endovascular approach.
RESUMO
Background: A pseudoaneurysm is an abnormal dilatation or outpouching of the artery which is lined only by the tunica adventitia. Pulmonary artery Pseudoaneurysm is very uncommon and associated with high mortality. Usually congenital but the acquired causes include trauma and infrequently infections mainly bacterial and fungal. Pulmonary mucormycosis is a rare opportunistic fungal infection seen in immunocompromised patients with diabetes, chronic renal failure, malignancies and is one of the most uncommon causes of pseudoaneurysm. Less than 30 cases have been reported worldwide for mucormycosis causing pulmonary artery pseudoaneurysm. Case 1: A 52 year old female who was COVID 19 positive 2 months back, admitted in RICU with recurrent hemoptysis and breathlessness. She is known Diabetic and Hypertensive. As her hemoptysis was persisting she underwent bronchoscopy and a soft mass was noticed in the right lower lobe bronchus which bleeds on touch. Bronchoalveolar lavage sent for microbiology confirmed Mucormycosis. CTPA done post bronchoscopy revealed pseudoaneurysm involving right descending pulmonary artery. Injection Amphotericin B started and surgical resection of right lower lobe done. Case 2: A 65 year old male, diabetic presented with cough and hemoptysis for 20 days with fever. CT thorax was suggestive of necrotising pneumonia in left lower lobe. As his hemoptysis was persisting Bronchoalveolar lavage was taken and the bronchoscopy showed a small swelling in the left lowerlobe bronchus. CECT Thorax was later done which confirmed descending pulmonary artery pseudoaneurysm. Treatment was same as for case 1. Discussion: Fungal pneumonia is a rare acquired cause of pulmonary artery pseudoaneurysm. The pseudoaneurysms are thin walled and easily ruptures producing massive hemoptysis. Infection accounts for 33% of the causes for pseudoaneurysms. Infective causes include pyogenic bacteria like S. pyogenes, S. aureus, Klebsiella and fungus like Mucor, and Aspergillus. Infection leads to chronic inflammation of vessel and leads to weakening of vessel wall which causes the internal layers to rupture. Mucor has the potential to cause direct invasion of the vessel wall leading to pseudoaneurysm. Conclusion: Pulmonary Artery Pseudoaneurysm and Pulmonary mucormycosis are individually uncommon clinical entities, but Pulmonary Artery Pseudoaneurysm due to underlying mucormycosis is a rare condition with a limited description in the literature. A high index of suspicion for both the clinician and radiologist is required and should be suspected in patients with underlying immunosuppression who develop hemoptysis. Pulmonary Artery Pseudoaneurysm can be successfully treated with embolization, but if mucormycosis is confirmed surgical resection is the only option.
RESUMO
Introduction: Pseudoaneurysm of the pulmonary artery (PAP) is a rare cause of hemoptysis with a wide array of aetiologies. This case report discusses our clinical experience of PAP associated with pulmonary mucormycosis (PM) in a COVID survivor. Case Report: A 58-year-old gentleman presented with a 1-week history of high-grade fever and progressive dry cough. Four weeks before his presentation, he was treated for mildly symptomatic COVID-19 infection with unusually high doses of steroids. On admission, a chest x-ray and CT chest showed a cavitatory lesion in the right lower lobe. He underwent a FOB with BAL and endobronchial biopsy, which were inconclusive. On day 5 of his hospital admission, he had an episode of massive hemoptysis leading to hemodynamic instability. CT showed an increase in the size of the cavity and a pulmonary angiogram showed the descending segmental branch of the right pulmonary artery traversing through the consolidative cavitating lesion with focal dilatation of the same measuring up to 1.5 x 1.9 cm. Consistent hemostasis couldn't be achieved after gluing an interlock coiling of pseudoaneurysm, hence he underwent video-assisted thoracic surgery for right lower lobectomy and stump ligation of the right lobar pulmonary artery. Lobectomy specimen on histopathology revealed large areas of necrosis with aseptate fungal hyphae. He responded well to antifungal therapy during follow on 4th week post discharge. Conclusion: Mucormycosis is characterized by angioinvasion, vessel thrombosis, and subsequent tissue thrombosis. Pseudoaneurysm formation is rarely seen in PM and can be associated with fatal hemoptysis. Irrational use of systemic steroids in the management of COVID makes the patient more vulnerable to an otherwise rare disease.
RESUMO
Background: Left ventricular (LV) pseudoaneurysm is a rare complication of myocardial infarction (MI) and difficult to diagnose. LV pseudoaneurysms form when cardiac rupture becomes contained within the pericardium. In those who survive the initial event, timely diagnosis is key as the condition often warrants emergency surgery. Case: A 78-year-old male with history of recent COVID-19 infection presented with pleuritic chest pain and near syncope. Chest computed tomography was notable for a large pericardial effusion as well as a hyperdense mass along the lateral aspect of the LV (Figure 1a). A transthoracic echocardiogram was performed;it showed significant wall motion abnormality of the lateral wall as well as a large, ill-defined pericardial or mediastinal echogenic dense mass impinging on the right atrium and ventricle. There was no evidence of tamponade physiology. Decision-making: Advanced imaging was required to further characterize the hyperdense mass. Cardiac MRI demonstrated a large, complex pseudoaneurysm emanating from the anterolateral wall of the LV with communication between the pseudoaneurysm and the pericardium (Figure 1b). MRI was also notable for full thickness delayed enhancement of the lateral wall consistent with infarction. Cardiac catheterization was notable for total occlusion of an obtuse marginal branch. Conclusion: This case highlights the importance of multi-modality imaging in detection of LV pseudoaneurysm, a potentially life-threatening complication of MI. [Formula presented]

RESUMO
Paradoxical intravascular bullet embolism involving the aortic arch (AA) is a rare and highly lethal condition. We describe an unusual case of a civilian gunshot injury to the neck. A bullet entered in the neck, injured the internal jugular vein (IJV), and then continued into the lumen of the common carotid artery (CCA). The bullet traveled under its own momentum and against the flow of blood, along the carotid and brachiocephalic vessels, finally lodging in the wall of the lesser curvature of the AA. The injury tract resulted in an arterial-venous fistula between IJV and CCA and a pseudoaneurysm of the AA. Open surgical repair of the neck and AA was complicated by secondary distal embolization of the bullet, requiring an embolectomy.
RESUMO
Pulmonary artery pseudoaneurysms (PAPs) are uncommon entities consisting of contained rupture of the pulmonary artery and are a potentially fatal cause of hemoptysis. We describe two index cases of left lower lobe PAPs and arterial ectasia post-COVID-19 pneumonitis and their endovascular treatment with Amplatzer vascular plug, coils, and glue.
