A Rare Case of Adult Acute Ileocecal Ischemia Related to Henoch-Schönlein Purpura: MDCT Findings.

Henoch-Schönlein purpura (HSP) is a form of immune complex-mediated leukocytoclastic vasculitis involving the skin and other organs. It primarily affects children. The occurrence of HSP in adults is rare, and gastrointestinal (GI) involvement is one of its most common clinical manifestations.

Laryngopyocele.

An apparently healthy 31-year-old man presented with dysphonia. Laryngoscopy revealed a mass at the right side of epiglottis. He underwent a CT examination after intravenous injection of a iodinated contrast agent and this showed the presence of a paralaryngeal mass with rim enhancement.

Atypical retroperitoneal extension of iliopsoas bursitis.

We report two rare cases of iliopsoas bursitis extending into the retroperitoneal space. The first lesion contained much gas, mimicking a retroperitoneal abscess, and the second was responsible for atypical inguinal pain. The diagnosis was made by contrast-enhanced CT in both cases and arthrography in the first case.
