A variety of benign cyst may occur in and around the ovary and broad ligament and may simulate serous cystadenomas. The majority of broad ligament and paraovarian epithelial tumors are serous neoplasms of low malignant potential and presented with a pelvic mass with or without ascites or pain, but without involvement of the ovary. Ovarian torsion and paraovarian serous cystadenoma are rarely reported.
We presented a case of giant paraovarian cyst in an 14-year-old girl, with characteristics of serous cystadenomas grossly and microscopically, and complicated with double adnexal torsion. A computed tomography scan showed large hypodense cystic mass (measuring 30 x 26 x 12 cm), occupying the whole abdominal cavity, with no adhesion to the surrounding organs.
Precise clinical data as well as pathological examinations based on immunohistochemical stainings were important in making the diagnosis. These rare cystic lesions of para/mesoovarian location in children and their unclear histogenesis might be a histopathological diagnostical problem.
多种良性囊肿可发生于卵巢及阔韧带内或其周围，可能类似浆液性囊腺瘤。大多数阔韧带和卵巢旁上皮性肿瘤为低恶性潜能的浆液性肿瘤，表现为盆腔肿块，伴或不伴有腹水或疼痛，但卵巢未受累。卵巢扭转合并卵巢旁浆液性囊腺瘤的报道较少。
我们报告了一例14岁女孩的巨大卵巢旁囊肿，大体及显微镜下均具有浆液性囊腺瘤的特征，并合并双侧附件扭转。计算机断层扫描显示巨大的低密度囊性肿块（大小为30×26×12cm），占据整个腹腔，与周围器官无粘连。
准确的临床资料以及基于免疫组织化学染色的病理检查对诊断至关重要。儿童中这些罕见的位于卵巢旁/中卵巢位置的囊性病变及其不明确的组织发生可能是一个组织病理学诊断难题。
