Multiple hepatic aneurysms in membranous nephropathy and autoimmune pancreatitis: appearances on contrast-enhanced ultrasound, ultrasound and angiography

Abstract

A 64-year-old man with histologically proven autoimmune pancreatitis and membranous nephropathy presented for evaluation of suspected liver metastases on computed tomographic abdominal scan. Ultrasound, contrast-enhanced ultrasound and visceral angiography demonstrated multiple hepatic artery aneurysms. Coil embolization of the largest aneurysm was undertaken successfully. The investigative findings indicate that necrotizing vasculitis was the underlying process, resulting in aneurysm formation. There is evidence that the smaller aneurysms have been effectively treated conservatively with immunosuppressive therapy.
