Gross hematuria: Renal cell carcinoma mimicking a renal arteriovenous malformation.

The differential diagnosis between renal arteriovenous malformations (AVM) and cancer may be a challenge, due to the similar clinical and imaging findings. Herein, we report the case of an 80-year-old male patient presenting gross hematuria, initially diagnosed and treated with embolization for a renal AVM. Due to the recurrence of hematuria and rapid progression and changes of the vascular lesion with detection also of an intralesional solid nodule, a radical nephrectomy was performed revealing the presence of a renal cell carcinoma (RCC). Renal cell carcinoma and renal AVM can be difficult to differentiate from one another, for this reason a short-term follow-up should be carried out in patients diagnosed and treated for renal AVM to confirm the resolution of AVM or to assess any changes, such as atypical neovascularization or intralesional renal masses, which may increase the suspect of a hidden renal tumor.

Radiation exposure and clinical outcome in patients undergoing percutaneous intradiscal ozone therapy for disc herniation: Fluoroscopic versus conventional CT guidance.

PURPOSE: To compare technical success, clinical success, complications and radiation dose for percutaneous intradiscal ozone therapy in patients with lumbar disc herniation using fluoroscopic guidance versus conventional computed tomography (CT) guidance. MATERIALS AND METHODS: Between March 2018and March 2021, 124consecutive percutaneous intradiscal ozone therapies wereperformedon111 patients with low back pain (LBP) and/or sciatic pain due to lumbar disc herniation, using fluoroscopic or conventional CT guidance, respectively in 53 and 58 herniated lumbar discs, with at least 1-month follow up. Dose area product (DAP) and dose length product (DLP) were recorded respectively for fluoroscopy and CT, and converted to effective dose (ED). RESULTS: Fluoroscopic and CT groups were similar in terms of patient age (p-value 0.39), patient weight (p-value 0.49) and pre-procedure Oswestry Disability Index (ODI, p-value 0.94). Technical success was achieved in all cases. Clinical success was obtained in 83.02% (44/53) patients in fluoroscopic group and 79.31% (46/58) in CT group. Mean DAP was 11.63Gy*cm2 (range 5.42-21.61). Mean DLP was 632.49mGy-cm (range 151.51-1699). ED was significantly lower in the fluoroscopic group compared toCT group (0.34 vs. 5.53mSv, p = 0.0119). No major complication was registered. Minor complications were observed in 4 cases (2 in fluoroscopic group; 2 in CT group). CONCLUSIONS: Compared to conventional CT guidance, fluoroscopic guidance for percutaneous intradiscal ozone therapy in patients with lumbar disc herniation shows similar technical and clinical success rates, with lower radiation dose. This technique helps sparing dose exposure to patients.

Nephrobronchial fistula a case report and review of the literature.

Nephrobronchial fistula is an extremely rare complications of renal infections. We present a case of nephrobronchial fistula in a middle age immunocompetent woman who complained cough and weight loss, with underlying asymptomatic nephrolithiasis. She underwent a chest X-ray that showed left lower lobe infiltrate and abdominal ultrasound. Abdominal ultrasound showed a complicated pyonephrosis ; CT of chest-abdomen-pelvis with intravenous contrast was performed in order to stage and define the extension of the pathology. At CT, a suspected diagnosis of stage III xanthogranulomatous pyelonephritis complicated with pyonephrosis and a nephrobronchial fistula was formulated. A nephrostomy tube was placed, and the patient was treated with antibiotics. Follow up CT, performed after 15 days, showed the healing of the fistulous connection between the perinephric abscess and bronchi; the patient underwent nephrectomy with no airway complication during intubation. Histopathological diagnosis confirmed the presence on complicated xanthogranulomatous pyelonephritis.

Malignant Gastric Outlet Obstruction Caused by Duodenal Cervix Metastasis in a Young Woman: Rendezvous Technique.

Background: Malignant gastric outlet obstruction (MGOD) is an extremely rare expression of advanced extra-gastrointestinal cancer, such as squamous cell carcinoma (SCC) of the cervix, and only sixcases are described in the literature.Because of the short life expectancyand the high surgical risk involving these patients, less invasive approaches have been developed over time, such asthe use of an enteral stent or less invasive surgical techniques (i.e., laparoscopic gastrojejunostomy). However, MGOD could make it difficult to perform an endoscopic retrograde cholangio-pancreatography (ERCP) for standard endoscopic drainage, so in this case a combined endoscopic-percutaneous technique may be performed. This article, therefore, aims to highlight the presence in the doctor's armamentarium of the "rendezvous technique", few case reports of whichare described in the literature, and, moreover, this article aims to underline the technique'sfeasibility. Case Presentation: The case is that of a 38-year-old woman who presented with MGOD three years after the diagnosis of SCC of the cervix, who successfully underwent the rendezvous technique with the resolution of duodenal obstruction. Endoscopic enteral stenting treatment with the placement of a metal stent (SEMSs) represents the mainstay of MGOD treatment compared withsurgery due to its lower morbidity, mortality, shorter hospitalization and earlier symptom relief. However, in patients with both duodenal and biliary obstruction, a combined endoscopic-percutaneous approach may be necessary because of the difficulty in passing the duodenal stricture or in accessing the papilla through the mesh of the duodenal SEMS. Conclusion: The rendezvous procedure is a technicallyfeasible and minimally invasive approach to the double stenting of biliary and duodenal strictures. It achieves the desired therapeutic result while avoiding the need to perform more invasive procedures that could have a negative impact on the patient'sprognosis.

Recovery of a broken PICC migrated in cardiac chambersan endovascular approach.

Complications related to the placement of a peripherally inserted central catheter are a common phenomenon and they can lead to acute complications which must be treated in an emergency regime. The aim of this study was to describe cases in their most practical and technical aspect, especially in complicated conditions. This was a descriptive case report of a 64 years old female patient who presented with a fractured peripherally inserted central catheter, migrated into the right heart chambers and inferior vena cava, and how the team arranged for its recovery by endovascular technique, in a frail patient who could not undergo to open surgery.The procedure was completed without any complications. The use of the endovascular technique allows a recovery of the foreign body in a short time, essential for a life-saving procedure; the interventional radiological approach allows less invasiveness in fragile patients and shorter hospitalization times.

Application of a personal Santini technique in the resolution of a complex celiac trunk aneurysm - endovascular treatment.

Aim Vascular pathologies have been already explored for the most of their aspects. It is a group of pathologies with unclear ethology and with an evolution in time not easy to forecast. Treatment guidelines are conflicting. The aim of this study was to describe cases in their most practical and technical aspect, especially in complicated conditions. Methods This was a descriptive case report of a patient with a hepatic artery aneurysm complicated by a dissection leading up to the splenic artery, and how the team had invented a planned treatment for the patient using a minimally invasive approach. The experience was born with the intention of showing how the endovascular approach is at least as safe as the traditional one despite the complexity of our case. Results The procedure was completed without any complications. After a stay in long day surgery, the patient returned home. Conclusion Using a minimally invasive technique allows to reduce the patient's post-operative suffering and the economic burden on the health system.

Ultrasound Signs in the Diagnosis and Staging of Small Bowel Obstruction.

Ultrasound (US) is highly accurate in the diagnosis of small bowel obstruction (SBO). Because the indications for and timing of surgical intervention for SBO have changed over the past several decades, there is a widespread assumption that the majority of patients with simple SBO may be conservatively managed; in this scenario, staging SBO is crucial. This study evaluated the association between morphological and functional US signs in the diagnosis and staging (simple, decompensated and complicated), and the associations and prevalence of US signs correlated with clinical or surgical outcome. The US signs were divided into diagnostic (dilated bowel loops and altered kinesis) and staging criteria (extraluminal free fluid, parietal and villi alterations). We performed a retrospective, single-center cohort, observational study examining the prevalence of morphologic and functional US signs in the staging of simple, decompensated and complicated SBO. The most significant US signs were dilated bowel loops (100%), hypokinesis (90.46%), thickened walls (82.54%) and free fluid (74.60%). By linear regression, free fluid was positively correlated to US staging in both univariate and multivariate analysis; that is, the more advanced the stage of SBO, the more probable the presence of free fluid between the bowel loops. In univariate analysis only, we found a positive correlation between US staging/thickened walls and the prominence of valvulae conniventes. Additionally, the multivariate analysis indicated that parietal stratification and bowel jump kinesis were negative predictors for US staging in comparison to other US signs. In addition, we found significant associations between conservative treatment or surgery and hypokinesis (p = 0.0326), akinesis (p = 0.0326), free fluid (p = 0.0013) and prominence of valvulae conniventes (p = 0.011). Free fluid in particular was significantly less present in patients that were conservatively treated (p = 0.040). We conclude that the US staging of SBO may be crucial, with a valuable role in the initial diagnosis and staging of the pathology, saving time and reducing total radiation exposure to the patient.

Ultrasound diagnosis of typhlitis.

PURPOSE: Typhlitis, also known as neutropenic colitis, is a rare inflammatory condition and a potentially life-threatening disease process that typically involves the cecum. Delay in diagnosis may lead to a fatal prognosis with a death rate of 21-48%. Ultrasound evaluation of right lower quadrant may lead to an accurate and rapid diagnosis. METHODS: We describe the case of a 59-year-old female with advanced Churg-Strauss syndrome treated with cyclophosphamide, with acute right lower quadrant pain. RESULTS: Ultrasound was the first diagnostic step in the diagnosis of typhlitis. Sonographic findings were comparable to CT imaging. CONCLUSIONS: Bowel bedside ultrasound evaluation in emergency settings may lead to a prompt and definitive diagnosis. Although CT is considered the gold standard in the diagnosis and staging of neutropenic colitis, ultrasound was able to identify the pathology accurately. Ultrasound findings of typhlitis are highly characteristic, showing circumferential wall thickening with predominant submucosa.
