CT Findings in Complications of Acquired Renal Cystic Disease

Renal neoplasms in patients with renal cystic diseases

“…They also noted that these patients had two significant complications, perinephric hemorrhage and renal tumor formation. ACKD is now a well-recognized clinical entity with the potential complications of renal cyst hemorrhage, cyst infection, matrix stone formation, renal cell carcinoma, and retroperitoneal bleeding [8][9][10].…”

“…The majority of patients with ACKD are asymptomatic [8][9][10]. The most common presenting complaint is flank pain due to spontaneous hemorrhage.…”

“…Hemorrhage into cysts probably occurs because unsupported sclerotic vessels in the cyst walls rupture. Bleeding may also be promoted by systemic heparinization during dialysis and platelet dysfunction due to uremia [9][10][11][12]. Bleeding may be confined to the cysts but can also extend into the renal collecting system or the retroperitoneum (Fig.…”

Uremic Acquired Renal Cystic Disease

“…These values are statistically signifi cant. As almost all renal cell tumors are diagnosed by screening tests which are able to detect small carcinomas, the prognosis for dialysis patients might be better than for those not on dialysis [7,26,53,74], However, the true biological activity of renal cell carcinoma in patients with acquired cystic disease as compared with that in the general population remains unknown.…”
