Bilateral ovarian metastasis from distal common bile duct carcinoma developing after choledochal cyst excision

ABSTRACT

Ovarian metastases represent about 3-5% of all ovarian malignancies. Most of these tumors originate in the digestive tract and cholangiocarcinoma rarely involves the ovary. A 60-year-old woman was admitted for the investigation of abdominal distension that had lasted 1 week. One and a half years prior, the patient had undergone choledochal cyst excision, Roux-en Y hepaticojejunostomy and cholecystectomy. Computed tomography scans of the abdomen revealed a papillary mass in the remnant distal common bile duct and enlargement of both ovaries with a huge amount of ascites. An explorative laparotomy disclosed no peritoneal seeding with resectable cholangiocarcinoma and bilateral ovarian mass. Pylorus-preserving pancreatoduodenectomy and bilateral salphingo-oophorectomy with hysterectomy were performed. Histologically, it was a well-differentiated adenocarcinoma and all surgical margins were free of tumor. Both ovarian masses were consistent with metastatic adenocarcinoma from the common bile duct. The patient received six cycles of postoperative adjuvant systemic chemotherapy, dying after 10 months due to pulmonary embolism.
