Abstract
Heterotopic glial nodule is a rare congenital non-neoplastic lesion that is characterized by ectopic brain tissue. It has occasionally been reported to affect areas such as the nose and face. The report presents a rare case of sacrococcygeal heterotopic glial nodule. Although teratomas are the most common neoplasms in this region, clinicians and radiologists should consider heterotopic glial nodule as a differential diagnosis, despite rarity and nonspecific imaging findings. Histopathology plays a crucial role in diagnosis, which intensely stains with glial fibrillary acidic protein and S-100.
