Acute pancreatitis revealing adult lymphocytic leukemia in a patient with double cystic duct: a rare case report.

Chronic lymphocytic leukemia (CLL) is an indolent B-cell lymphoproliferative disorder often discovered incidentally through routine blood tests. Acute pancreatitis (AP) is a common abdominal emergency, typically of biliary or alcoholic etiology. We report an unusual case of a 63-year-old woman presenting with AP due to biliary lithiasis, which led to the incidental diagnosis of CLL. Notably, intraoperative findings revealed a rare anatomical anomaly: double cystic duct. This case underscores the importance of systematic etiological exploration in AP and highlights potential surgical implications of biliary anomalies in oncologic and inflammatory settings.
