Acute epiploic appendagitis : ultrasound and computed tomography findings of a rare case of acute abdominal pain and the role of other imaging techniques

Purpose: Acute epiploic appendagitis (EA) is a relatively rare, benign and local inflammatory disease involving the epiploic appendices. Unlike its mimics, EA is generally a self-limiting inflammatory disease and can be treated conservatively. Case presentation: A 33-year-old Caucasian man presented to our emergency department with a sever and sharp left iliac fossa pain. He underwent abdominal X-ray, ultrasound (US) and computed tomography (CT) evaluations. Conclusion: We illustrate US and CT findings to increase the radiologists’ awareness of this condition and to avoid diagnostic delay and unnecessary use of antibiotics, hospitalization and surgery

Stent-Graft Repair of Concomitant Occlusion and Anastomotic Pseudoaneurysm in a Prosthetic Femoropopliteal Bypass

Both occlusion and pseudoaneurysm are complications of femoropopliteal bypass surgery. Open revision is the gold standard, but it is associated with high morbidity and mortality compared with endovascular treatment. Percutaneous stent-graft repair is a valid option either for recovering the patency of occluded prosthetic femoropopliteal bypass or for excluding anastomotic pseudoaneurysm. In this report, it is presented a case of occlusion concomitant to a pseudoaneurysm of the distal anastomosis in a previous prosthetic femoropopliteal bypass; a simultaneous endovascular treatment of both complications has been performed through self-expanding stent-graft (Viabahn) placement

COVID-19 integrated imaging: our experience and literature review

Purpose: To investigate the imaging features of emerging COVID-19 pneumonia on chest ultrasound, radiographs and computed tomography examinations performed at admission. In addition, we provide a review of the literature and compare our results with recent evidence regarding the imaging characteristics of this novel disease. Material and methods: From March 17, 2020 to April 25, 2020, 23 patients with real-time polymerase chain reaction (RT-PCR) assay confirmed COVID-19 were identified. All 23 patients were evaluated and admitted at San Giuseppe Moscati Hospital in Aversa, Italy. Multi-modality imaging findings were evaluated and compared. Literature research was conducted through a methodical search on PubMed. Results: Twenty-three patients were included in the study. Chest transthoracic ultrasound (US), chest X-ray (CXR), and computed tomography (CT) were performed respectively in 11, 16 and 21 patients. Chest US findings were consistent with diffuse B lines (91%), subpleural consolidations (45%), and thickened pleural line (18%). CXR showed prevalent manifestations of consolidations (50%) and hazy increased opacities (37%). Typical CT features are bilateral and multilobar ground-glass opacities (GGO). Indeed GGO were present in 100% of our patients. Consolidations were visible in 76% of our study population. Notably both GGO and consolidations had a peripheral distribution in all our patients. Other CT imaging features included crazy-paving pattern, fibrous stripes, subpleural lines, architectural distortion, air bronchogram sign, vascular thickening and nodules. Our literature review identified thirty original studies supporting our imaging chest findings. Conclusions: At admission, COVID-19 pneumonia can manifest in chest imaging as B-lines and consolidations on US, hazy opacities and consolidations on CXR, multiple GGO and consolidations on CT scan

Go-BACK catheter for treatment of iliac artery chronic total occlusion: A case report

The Go-BACK catheter is a novel device designed to be used for both intraluminal crossing or re-entry, into a vessel lumen from the subintimal space during subintimal angioplasty.It is reserved for cases where reentry has not been possible using conventional wire and catheter techniques. We report our experience in recanalization of the chronic total occlusions of the common iliac artery (CIA) using the Go-BACK catheter, in cases where other techniques were unsuccessful
