Autosomal Dominant Polycystic Kidney Disease (ADPKD) Complications: Berry Aneurysm on CT Scan, Diverticulitis on BE

Findings

• The CT demonstrates a berry aneurysm off the Circle of Willis.
• The BE demonstrates diverticulosis of the sigmoid with eccentric mass effect due to an intramural diverticular abscess i.e. diverticulitis.

Discussion

ADPKD is one of three major inherited cystic diseases of the kidney. The kidneys become markedly enlarged with cysts. These distort the calyces and renal outline and cause mass effect on surrounding organs. The kidneys are abnormal and frequently show dystrophic calcifications. The liver and pancreas frequently contain cysts. There is an increased incidence of diverticular disease of the colon. There is an increased incidence of cerebral artery aneurysms.
