Epoprostenol-induced hypersplenism in portopulmonary hypertension.

Portopulmonary hypertension (POPH) is a not infrequent but serious complication of liver cirrhosis. Continuous intravenous epoprostenol infusion is a treatment option for this condition. Progressive splenomegaly with pancytopenia (hypersplenism) is associated with epoprostenol use in POPH.

Bilateral renal artery dissection following extreme exertion.

Dissection of a renal artery is rare and is usually associated with underlying arterial disease. Bilateral renal artery dissection following extreme exertion is exceptionally uncommon, and thus presents a diagnostic challenge. We report a case of a middle-aged, otherwise healthy man who presented to the hospital with left flank pain after a long bicycling trip.

Incidental diagnosis of thrombus within an aneurysm on 18F-FDG PET/CT: frequency in 926 patients.

Unlabelled: Our objective was to evaluate the incidence of aneurysm and the frequency of thrombus within an aneurysm on unenhanced (18)F-FDG PET/CT studies.

Methods: We reviewed 1,540 PET/CT scans from 926 patients. A log recorded whether each case of aneurysm had a suspected thrombus.
