Splenic artery aneurysm in a patient of autosomal dominant polycystic kidney disease: beyond tenuous concomitance!

Splenic artery aneurysm (SAA) is rare, with risk of rupture especially if diameter is >2 cm. It is usually asymptomatic and detected incidentally on imaging either in young pregnant women or elderly cirrhotic patients. Extracranial vascular abnormalities known to be associated with autosomal dominant polycystic kidney disease (ADPKD) include ascending aortic aneurysms, dissections of coronary and vertebral arteries and rarely SAA. We describe a rare case of incidentally detected SAA in a patient with end stage renal disease due to ADPKD during evaluation of persistent gross haematuria, with no evidence of cranial or other extracranial aneurysms. © BMJ Publishing Group Limited 2019.
