Vanishing splenic cyst- visible on ultrasound but non-detected on MRI.

This paper ilustrates the imaging aspect of a rare pathology- aorto-mesenteric compression syndrome (Wilkie's disease). In this disease acute angulation of the superior mesenteric artery will lead to compression of the duodenum and of the left renal vein. Duodenal compression may lead to delayed gastric emptying and to nutcraker syndrome when left flank pain and hematuria may be present.
