Hydatid cyst of the pancreas mimicking choledochal cyst

Abstract

Primary hydatid cyst of the pancreas represents a rare clinical entity. The clinical presentation depends on the location of a hydatid cyst in the pancreas. A hydatid cyst located in the head of the pancreas usually manifests as obstructive jaundice due to the extrinsic compression of the common bile duct. A case of a hydatid cyst of the head of the pancreas in a 4-year-old female is reported. She presented with abdominal pain and jaundice. Contrast-enhanced computed tomography scan of the abdomen revealed a cystic mass at the lower end of the common bile duct, which mimicked a choledochal cyst. The diagnosis of hydatid cyst was made intraoperatively, with postoperative findings revealing a hydatid cyst at the head of the pancreas that was compressing the lower end of the common bile duct. After cystectomy, no recurrence was seen in follow-up.

“…The second route involves passage of cystic elements into the biliary system and then to the pancreatic canal and pancreas [3,10,14,27] . The third route involves passage of cystic elements into lymphatic channels through the intestinal mucosa and then to pancreatic tissue rich in lymphatic network [3,8,[10][11][12]14,20,27] . The fourth route is direct passage of larvae into pancreatic tissue, bypassing the liver, via pancreatic veins [20] .…”

“…Hydatid cysts located in the pancreatic head may cause obstructive jaundice or acute pancreatitis by either exerting external compression on or fistulizing into the common bile duct [4,10,12,15,20,23,[26][27][28][29][30]31,35,36] . Less commonly, they may lead to cholangitis, duodenal stenosis, or duodenal fistula [4,20] .…”
