Splenic artery aneurysm: a rare complication of autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is an important cause of renal dysfunction. It is the most common genetic disorder leading to end-stage kidney disease requiring dialysis. ADPKD is a multisystem disease and is linked to several extra renal abnormalities. Splenic artery aneurysms are rare in the general population. ADPKD is associated with cerebral artery aneurysms. However, splenic artery aneurysms are not a well-recognised complication of ADPKD. We report an unusual case of a splenic artery aneurysm found incidentally on abdominal CT imaging of a woman with known ADPKD.
