Last revised by Daniel J Bell on 21 Apr 2023

Gliomatosis peritonei is very rare and is characterized by the implantation of benign mature glial tissue in the peritoneum, omentum, and/or lymph nodes. It is usually associated with ovarian teratoma, although has rarely been seen with other teratomas 1-4.

Rarely gliomatosis peritonei has also been described in the context of a ventriculoperitoneal shunt 5.

Bar a single case report from 2015, all adult cases of gliomatosis peritonei have been in females 6.
