Incidental finding or the incognito culprit? A case of Mounier-Kuhn syndrome.

Mounier-Kuhn syndrome, characterized by tracheal dilatation due to the loss of elastic fibers and smooth muscle cells, is a rare condition, often leading to recurrent respiratory infections from impaired mucociliary clearance.

A rare occurrence of isolated superior mesenteric artery dissection, a case image report.

Isolated spontaneous superior mesenteric artery (SMA) dissection is relatively rare. Often found incidentally on cross-sectional imaging, often managed non-operatively. We present a patient who presented with chest pain and was found to have a SMA dissection.

A Case of Incidental Left Ventricular Aneurysm.

Post MI left ventricular aneurysm (LVA) may be incidental, yet it presents potential risks such as heart failure, arrhythmias, thromboembolism. Monitoring and vigilant follow-up are essential to promptly identify LVA in patients with risk factors.

A Rare Case of Immunoglobulin G4-Related Constrictive Pericarditis Diagnosed Via Multimodality Imaging.

Constrictive pericarditis (CP) presents as a pathophysiological state where the pericardium becomes inelastic due to fibrotic changes, most commonly secondary to a protracted inflammatory process. The disease is characterized by compromised diastolic cardiac function due to loss of pericardial compliance. Immunoglobulin G4 (IgG4)-related disease, an entity marked by the insidious proliferation of IgG4-positive plasma cells and subsequent fibrosis within various organs, is an infrequent but recognized cause of CP. A case of a 55-year-old male patient with clinical manifestations of dyspnea and edema in the lower extremities elucidates the diagnostic complexity inherent to CP. Echocardiography revealed a constellation of signs, including annulus reversus, septal bounce, and a congested inferior vena cava; cardiac magnetic resonance imaging (MRI) demonstrated diffuse pericardial thickening with delayed gadolinium enhancement, suggestive of a long-term inflammatory state; and right heart catheterization confirmed the hemodynamic hallmark of CP-equalization of diastolic pressures across the cardiac chambers. The serological analysis elicited elevated serum levels of IgG4 and IgE, pointing to the differential diagnosis of IgG4-related disease. Given the nonspecific clinical presentation of IgG4-related CP, a heightened index of suspicion combined with a systematic approach to imaging and serological evaluation is paramount.

Carbohydrate Antigen (CA 19-9) Surge: Unraveling the Enigma of Elevated Levels in the Setting of Benign Etiologies.

Carbohydrate antigen 19-9 (CA 19-9) is widely recognized as a tumor marker primarily associated with pancreatic cancer. However, its elevation in benign pancreaticobiliary conditions complicates its diagnostic utility. We present the case of a 39-year-old male with no significant medical history who presented with symptoms of abdominal pain, nausea, vomiting, and diarrhea. The initial diagnosis suggested viral enteritis, but the subsequent worsening of symptoms led to further investigation. Elevated white blood cell counts, bilirubin levels, and liver function tests prompted magnetic resonance cholangiopancreatography (MRCP), which revealed dilated bile ducts and acute cholecystitis. Following endoscopic retrograde cholangiopancreatography (ERCP), significant hemobilia was observed, raising suspicions of cholangiocarcinoma. Despite extensive investigations, including CT angiography, MRCP, and repeat ERCPs, no malignancy was detected. Remarkably, the CA 19-9 level was elevated to 904 U/mL after the initial ERCP and uptrended to 7380 U/mL. These levels, however, normalized to 13 U/mL within two weeks of discharge. While CA 19-9 is a valuable marker in the diagnosis of pancreatic cancer, its elevation in benign pancreaticobiliary conditions necessitates cautious interpretation. In our case, choledocolithasis, cholangitis, and biliary manipulation appeared to have contributed to a transiently elevated CA 19-9. Clinicians must consider the entire clinical context when evaluating elevated CA 19-9 levels to avoid misdiagnosis and ensure appropriate patient management.

Unilateral renal fungus ball caused by Candida glabrata.

A 46-year-old diabetic woman with unilateral renal fungus ball was successfully treated with antifungal therapy, endoscopic extraction and ureteral stent placement. The patient was initially treated for a right staghorn calculus, thereafter developed urinary symptoms. Imaging revealed distal left ureter filling defects and a previous stent at the ureteropelvic junction. Urine culture confirmed Candida glabrata sensitive to Micafungin. Bilateral ureteroscopy facilitated the extraction of a left renal pelvis fungus ball. This case underscores the challenges in diagnosing fungal UTIs in patients with predisposing factors, and highlights a combined medical and surgical approach for effective treatment of renal fungus balls.

The Great Imitator: A Case of Lyme Carditis Mimicking ST Elevation Myocardial Infarction.

Lyme disease, caused by Borrelia burgdorferi and transmitted via Ixodes ticks, is a common vector-borne illness in the United States, with an estimated 476,000 annual cases. While primarily known for its neurological and rheumatological manifestations, Lyme disease can also involve the cardiac system, known as Lyme carditis, which occurs in about 4% to 10% of cases. This case report details a rare instance of Lyme carditis presenting as ST-segment elevation myocardial infarction (STEMI) in a 31-year-old female with no significant medical history. The patient exhibited symptoms of chest pressure and shortness of breath, with laboratory results showing significantly elevated troponin levels and other indicative markers. Notably, cardiac catheterization revealed no coronary occlusion, suggesting an alternative diagnosis to acute coronary syndrome (ACS). Further testing confirmed Lyme carditis through positive serological tests for Lyme-specific IgM antibodies. The case underscores the importance of considering Lyme myopericarditis in differential diagnoses for STEMI in Lyme-endemic areas and in patients without typical risk factors for coronary artery disease. This report aims to increase clinical awareness of this condition, highlighting the need for thorough investigation in atypical cardiac presentations.

Cocaine Gut: A Rare Case of Cocaine-Induced Esophageal, Gastric, and Small Bowel Necrosis.

Cocaine is an indirect-acting sympathomimetic drug that inhibits norepinephrine and dopamine reuptake in the adrenergic presynaptic cleft. Cocaine use has been associated with strokes, angina, arrhythmias, and agitation. Data on gastrointestinal complications such as mesenteric ischemia, bowel necrosis, ulceration, and perforation are scarce. Here, we present a rare case of cocaine-induced esophageal, gastric, and small bowel necrosis that contributes to the limited literature on this subject. Diagnosis of cocaine-induced gastrointestinal complications involves a combination of imaging studies, laboratory assessments, and histopathological examinations. Timely surgical resection, supported by intravenous fluids, antibiotics, and pain management, is the mainstay of treatment. The prognosis varies but is significantly influenced by the promptness and effectiveness of the intervention, underscoring the importance of vigilant clinical care in such cases.

Splenic Surprise: Investigating a Case of Splenic Infarct as an Isolated COVID-19 Manifestation.

Coronavirus disease 2019 (COVID-19) infection has been associated with a multitude of complications, one established complication being thromboembolism, a result of the proinflammatory state induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This prothrombotic state is a cumulation of many inflammatory pathways at work. Here, we present an interesting case of a 43-year-old female who did not present with the typical COVID-19 clinical picture. Instead, she presented with periumbilical pain, nausea, and vomiting. Upon further investigation, she was found to have a splenic infarct on a computed tomography (CT) scan. An extensive workup was performed to explore possible etiologies; however, it was concluded that her splenic infarct was secondary to her COVID-19 infection. With this case, we aim to add to the literature regarding the manifestations of the prothrombotic state of SARS-CoV-2.

Rare Case of Mycobacterium Avium Complex Peritonitis in a Patient with Multiple Myeloma Undergoing Peritoneal Dialysis.

Mycobacterium avium complex (MAC) infections can present as a variety of severe diseases. While it has a predilection for immunocompromised patients such as those with Human immunodeficiency virus (HIV), it can also affect immunocompetent patients as well. One of the rare yet severe diseases that MAC infections can present is MAC peritonitis. Often hard to distinguish from other causes of peritonitis, high clinical suspicion should be maintained for those who are susceptible. Here we present an 85-year-old female with a past medical history of end-stage renal disease on peritoneal dialysis who presented with nausea and vomiting. She was found to have tenderness around her peritoneal dialysis site and was noted to have mild ascites. Her labs were significant for several electrolyte abnormalities, leukocytosis, and ascitic fluid obtained during a previous admission, and serology was positive for acid-fast bacilli. It was further revealed that the species was Mycobacterium avium complex. Initially, she started on rifampin, isoniazid, pyrazinamide, and ethambutol (RIPE), subsequently antibiotics were changed to azithromycin, ethambutol, and rifampin after MAC identification in acid-fast bacilli culture. We aim to highlight this rare presentation of peritonitis secondary to MAC.

A symphony of anomalies: Isolated pulmonary artery agenesis meets congenital lung hypoplasia.

Isolated agenesis of pulmonary arteries with congenital lung hypoplasia is rare. It can be found in childhood or adulthood if asymptomatic. We present a patient with congenital right lung hypoplasia with an absent right pulmonary artery.

Sinistral Portal Hypertension Due to a Pancreatic Pseudocyst: A Rare Cause of Upper Gastrointestinal Bleeding.

Sinistral portal hypertension (SPH), also known as segmental portal hypertension, is a complication of pancreatic disorders and an extremely rare cause of upper gastrointestinal (GI) bleeding. SPH is observed in patients without cirrhosis and arises from splenic vein thrombosis. Unmitigated backflow of blood may cause gastric venous congestion and ultimately GI hemorrhage. Herein, we report a rare case of massive hematemesis due to SPH in a male patient with a history of chronic pancreatitis and pancreatic pseudocyst. Our patient was successfully treated with endoscopic necrosectomy followed by open splenectomy, distal pancreatectomy, and partial gastric resection.

Cranial Conundrum: An Unusual Case of an Epidermoid Cyst in the Prepontine Cistern.

We present a fascinating case of a patient who suffered from persistent headaches for three months due to an epidermoid cyst located in the prepontine cistern. Epidermoid cysts are a very uncommon type of intracranial tumor, known for their slow growth and gradual onset of neurological symptoms. In this particular case, our patient, a 35-year-old, experienced a headache that was accompanied by dizziness, photophobia, and pain when moving their eyes. Further imaging revealed a cystic lesion in the prepontine cistern, which had a mass effect on the pons. After confirming the lesion was likely an epidermoid cyst through an MRI, the patient underwent surgery to have it removed. We hope to highlight the rarity of this type of tumor and its unique features when viewed through imaging.

An Interesting Case of Asymptomatic Cholera in the Setting of Large Bowel Obstruction.

Vibrio cholerae is the culprit behind many endemics globally. Classically characterized by profuse diarrhea with a "rice water" description, cholera can be fatal if not treated promptly. However, infected individuals can present with little to no symptoms. These individuals allow for a carrier state and play a large part in the survival of an endemic. Asymptomatic patients can present in areas where Cholera is not endemic. Herein, we present an atypical case of vibrio chloerae infection without diarrhea in the setting of large bowel obstruction secondary to colon cancer. We aim to highlight the unusual presentation of a cholera infection.

A rare case of dual coronary cameral fistulae.

Key Clinical Message: Dual coronary cameral fistulae (CCFs) are rare abnormal connections between coronary arteries and heart chambers. Management of CCFs remains a topic of debate, emphasizing the need for individualized approach based on presentation. Abstract: We present a rare case of dual coronary cameral fistulae originating from the mid-left anterior descending (LAD) and the mid-right coronary artery (RCA) with drainage into the left ventricle, diagnosed incidentally during coronary angiography.

An Interesting Presentation of Pneumomediastinum Secondary to Hyperemesis Gravidarum in the Second Trimester.

We present a rare case of pneumomediastinum in the setting of hyperemesis gravidarum. Pneumomediastinum is a condition characterized by the presence of air leaking into the mediastinum. Often secondary to trauma, there remains the potential for it to develop spontaneously. This is a time-sensitive diagnosis that requires vigilance for effective treatment. A 21-year-old gravida 1 para 0 female at 15 weeks of gestation with no significant past medical history presented to the emergency department complaining of four weeks of daily nausea and vomiting and two weeks of chest pain, cough, and difficulty breathing. Computed tomography angiography of the chest revealed the presence of subcutaneous air in the mediastinum, and esophageal rupture was ruled out by a gastrografin esophagram. Due to extensive pneumomediastinum and severe metabolic derangements, the patient was admitted to the intensive care unit. A gastrografin esophagram was obtained, which showed no esophageal tear.No surgical intervention was performed, and she was managed with conservative treatment. This case illustrates some of the severe complications of pregnancy. Although pneumomediastinum secondary to hyperemesis gravidarum seen in this patient is rare (the incidence of pregnancy-related pneumomediastinum has been noted to be 1:100,000), it is an important adverse complication that the clinician should keep in mind in pregnant patients with hyperemesis gravidarum. Providing education to patients during the prenatal process can help identify the signs and symptoms of this condition to prevent potentially fatal consequences.

The Cancer Diaspora: A Rare Case of Pseudomyxoma Peritonei of Appendiceal Origin.

Pseudomyxoma peritonei (PMP) is a rare clinical entity characterized by widespread mucinous implants in the peritoneal cavity. Commonly seen in females in their 50s, PMP typically originates from ruptured appendiceal mucoceles that find refuge in the peritoneal space. Rarely, PMP may originate from the ovary, stomach, colon, or pancreas. Pseudomyxoma peritonei of colorectal origin is more malignant and has a lower survival rate. We report a case of a 59-year-old Hispanic woman with PMP who presented to the emergency room with a 3-month history of progressive abdominal distention. Pseudomyxoma peritonei was confirmed by computed tomography (CT) scan of the abdomen and pelvis and histopathology, and the patient underwent partial cytoreductive surgery. Given her Eastern Cooperative Oncology Group (ECOG) performance status of 1 despite extensive carcinomatosis, our patient may benefit from hyperthermic intraperitoneal chemotherapy (HIPEC) in the future.

An Interesting Case of Methicillin-Resistant Staphylococcus aureus Prostate Abscess in an Immunocompetent Patient.

Prostate abscess is a rare complication of prostatitis, typically observed in patients with conditions such as immunodeficiency, diabetes, urinary tract abnormalities, and chronic indwelling catheters. Gram-negative bacteria such as Enterobacteriaceae are the most commonly detected organisms in prostate abscesses. Methicillin-resistant Staphylococcus aureus (MRSA) infections are rarely reported. The unique aspect of our case involves MRSA bacteria, further complicated by an MRSA prostate abscess, in a 61-year-old immunocompetent male. The patient, with a past medical history of hypertension and diabetes, presented to the emergency department complaining of nausea and vomiting for four days, with an associated subjective fever and right-sided abdominal pain. A computed tomography (CT) scan of the abdomen/pelvis with contrast showed a prostatic abscess, with abscess/phlegmon extending bilaterally into the seminal vesicles. Urine and blood cultures were positive for MRSA. Initially, Piperacillin/Tazobactam and Vancomycin were initiated. Subsequently, the treatment was switched to Daptomycin. The patient also underwent cystoscopy with urethral dilation, transurethral prostate resection, and unroofing. Although MRSA is not a typical causative agent of prostatitis, it should be considered in the differential diagnosis, especially when clinical improvement cannot be achieved with standard empirical treatment. Timely identification and appropriate treatment (such as drainage and antibiotics) are crucial for both patient survival and the prevention of complications.

When a Tooth Pulls the Heart Strings: Takotsubo Cardiomyopathy Post-dental Extraction.

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy, is a temporary left ventricular dysfunction caused by a catecholamine surge under severe stress. It's characterized by chest pain, non-specific ECG changes, and left ventricular apical ballooning observed during catheterization. We present a case of a 59-year-old postmenopausal female with a past medical history of asthma who arrived at the ED complaining of chest pain following dental extraction. The patient's abnormal ECG findings and elevated cardiac enzymes required cardiac catheterization, which revealed normal coronary vasculature but demonstrated left ventricular apical ballooning. Transthoracic echocardiogram (TTE) showed septal left ventricular hypertrophy, decreased ejection fraction (EF), and akinetic segments consistent with takotsubo cardiomyopathy. Secondary takotsubo cardiomyopathy induced by stress in the setting of dental procedures like a tooth extraction for a periapical dental abscess is rarely described in the literature. Our case serves as a reminder of the potential for stress-induced cardiomyopathy in postmenopausal women, especially those with undiagnosed underlying anxiety disorders, even following minimally invasive procedures.

Managing Patent Foramen Ovale (PFO) in Adults With Cryptogenic Stroke and Lymphoma: A Multidisciplinary Perspective.

​​Cryptogenic strokes are strokes with no clear underlying cause. Patent foramen ovale (PFO) is believed to be one of the causes of cryptogenic strokes. To manage such cases, closing the PFO is usually considered an option. We report a case of a middle-aged male with lymphoma who presented with an altered mental status due to a stroke, which, on investigation, was found to be due to an underlying PFO. This report explores the factors that must be considered when making the decision to close the PFO and emphasizes the vital role of a multi-disciplinary team in determining the best course of action for patients with cryptogenic strokes.
