Introduction: Solid teratomas are relatively more common in infants and children (accounting for 15% of ovarian tumor). Though the peak age incidence is at second decade ^[1]. Metastatic implantation of glial tissue on surfaces of visceral or parietal peritoneum is called as Gliomatosis peritonei (GP) and its occurrence is very rare.

Case Report: A 10 year old girl presented with the complaints of vague abdominal pain and discomfort for two months. Ultrasonography of the abdomen showed a heterogenous solid cystic tumor of 12 X 15 x 10 cm noted in left side of the ovary adherent to the fallopian tube. Left salpingoopherectomy was done and histopathology show features of mature solid ovarian teratoma with Gliomatosis peritonei.

Conclusion: Gliomatosis peritonei is implantation of mature glial tissue on surfaces of peritoneum. It is often associated with ovarian teratoma of any grade. This is always present with massive peritoneal implantation, optimal resection is difficult. Although residual peritoneal disease can be totally quiescent over a long period, long-term follow-up is needed for patients with residual disease. A more conservative surgical approach may be carried out in patients with massive peritoneal spread.
