Gliomatosis peritonei (GP), almost exclusively linked to mature or immature ovarian teratoma, is a very rare disease. To the best of our knowledge, reports on the complete clinical course and imaging features of ovarian mature teratoma with GP are extremely rare. We present a case of ovarian mature teratoma with GP in a 9-year-old girl admitted to the emergency department for a 2-month history of a large abdominal mass found accidentally. Carcinoembryonic antigen and cancer antigen 125 levels were elevated. CT scans suggested a large mass with mild enhancement, and an immature teratoma derived from the left ovary with ascites was diagnosed by ultrasound. Subsequently, left ovarian tumor resection and omentectomy were performed, and a solid cystic mass accompanied by massive ascites and numerous white to grayish nodules was identified on the left ovary. The pathology results revealed a mature teratoma with GP. The patient had good postoperative recovery, and her serum tumor marker levels decreased to normal at the 3-month follow-up.
腹膜胶质瘤（GP）几乎仅与成熟或不成熟卵巢畸胎瘤相关，是一种非常罕见的疾病。据我们所知，关于伴有 GP 的成熟卵巢畸胎瘤的完整临床病程和影像学特征的报告极为罕见。我们报告了一例 9 岁女孩的病例，该患者因偶然发现的 2 个月大的巨大腹部肿块而被收入急诊科。癌胚抗原和癌抗原 125 水平升高。CT 扫描提示存在轻度增强的巨大肿块，超声诊断为来源于左侧卵巢的伴腹水的未成熟畸胎瘤。随后进行了左侧卵巢肿瘤切除术和网膜切除术，在左侧卵巢上发现了一个伴有大量腹水和许多白色至灰白色结节的实性囊性肿块。病理结果显示为伴有 GP 的成熟畸胎瘤。患者术后恢复良好，在 3 个月的随访时其血清肿瘤标志物水平降至正常。
