A Case of Huge Infected Adrenal Pseudocyst associated with Acute Pyelonephritis and E. coli Bacteremia / 대한신장학회지

ABSTRACT

A 61-year-old woman was presented with fever and pain in both flanks. Computed tomography (CT) revealed a septated heterogenous giant mass suggesting a huge suprarenal cyst. Percutaneous drainage was performed. Escherichia coli was cultured in blood, urine and aspirated fluid from the cyst. Therefore, it was initially diagnosed as infected renal cyst with acute pyelonephritis. However, follow-up CT after drainage of the cyst and surgical findings revealed the cyst grew not from the kidney but from the adrenal gland. Postoperative finding and pathologic study confirmed it was originated from adrenal. We describe a case of E.coli infected huge adrenal pseudocyst misunderstood as an infected renal cyst because of indistinct anatomical boundary and association with acute pyelonephritis.
