• 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. Ultrasonographic features of mature teratomas with GP. A‐B. A mature teratoma with well‐defined boundaries manifested as heterogeneous internal echoes containing punctate calcifications (arrowhead), slightly hyperechoic regions and cystic areas (arrow). C. The colour Doppler sonogram showed feeding arteries of the tumour originating from the left ovarian artery. D. Several miliary nodules (white circle) were identified in the peritoneum, and massive ascites (arrow) was detected in the abdomen and pelvis.
