A Rare Case of Granulomatosis with Polyangiitis-Related Periaortitis at the Ascending Aorta

Acute aortic syndrome including intramural hematoma is a life-threatening disease encountered in the emergency department with high in-hospital mortality even when a timely diagnosis is made. Therefore, accurate differential diagnosis of acute aortic syndrome and its mimics is important to determine the patient's treatment plan. Until now, a few pathologic diseases mimicking aortic intramural hematoma such as periaortic lymphoma and immunoglobulin G4-elated periaoritis have been reported. Here, we report a rare case of granulomatosis with polyangiitis-related periaortitis misdiagnosed as aortic intramural hematoma presenting to the emergency department with chest pain and similar radiologic findings.

Complication Following Ultrasound-Guided High-Intensity Focused Ultrasound for the Treatment of Uterine Adenomyosis: Case Report of CT Imaging Features

High intensity focused ultrasound (HIFU) is a non-surgical and non-invasive treatment option in patients with uterine myoma and adenomyosis. As the use of HIFU increases in the clinical practice, it is important to be aware of imaging findings related to ultrasound (US)-guided HIFU ablation and its potential complications. However, there are few reports on the imaging findings regarding complications of US-guided HIFU ablation. Here, we report a case of acute complication after US-guided HIFU ablation, surgically confirmed as thermal injury with necrosis of skin, subcutaneous tissue, anterior abdominal wall muscles, peritoneum and uterus.
