Mucinous cystic neoplasms (MCN) of the pancreas are rare tumors that are almost exclusively located in the body or the tail of the pancreas. A 60-year-old woman with no history of pancreatic disease was referred to our hospital with a chief complaint of dull pain in the upper abdomen. Abdominal computed tomography showed a multilocular cystic mass of 7.0 cm in the head of the pancreas, and endoscopic retrograde cholangiopancreatography showed no communication between the cystic mass and the main pancreatic duct. A pancreatoduodenectomy was performed for the complete resection of the tumor, and an annular pancreas was discovered by accident. The pathological examination of the tumor led to a definitive diagnosis of MCN with ovarian-type stroma. To our knowledge this is the first documented case of MCN occurring in the head of the pancreas and associated with annular pancreas.
胰腺黏液性囊性肿瘤（MCN）是一种罕见的肿瘤，几乎仅发生于胰腺体尾部。一位 60 岁女性，无胰腺疾病史，因上腹部钝痛就诊于我院。腹部 CT 显示胰头部有一 7.0cm 的多房囊性肿块，内镜逆行胰胆管造影显示该囊性肿块与主胰管之间无交通。行胰十二指肠切除术以完全切除肿瘤，术中意外发现环状胰腺。肿瘤的病理检查明确诊断为 MCN，伴卵巢型间质。据我们所知，这是首例发生于胰头部并伴发环状胰腺的 MCN 病例。
