Abstract
Peritoneal and nodal gliomatosis is a rare disease condition characterized by implants of mature glial tissue on the peritoneum and lymph nodes. It is typically associated with teratoma and has no adverse effect on prognosis. We present a case of 22-year-old woman who underwent FDG PET/CT for the staging of ovarian immature teratoma. PET/CT revealed mildly increased FDG uptake in the peritoneal cavity and increased FDG uptake in the internal mammary and cardiophrenic angle lymph nodes, which were histopathologically diagnosed as peritoneal and nodal gliomatosis. This case suggests that PET/CT findings of peritoneal and nodal gliomatosis could mimic metastasis.
