Clinicopathological insights of supratentorial embryonal tumor with medulloblastoma‑like histopathology in adulthood: A case report

Embryonal tumor with medulloblastoma-like histopathology (ETMH) is an embryonic-type malignancy originating from remnants of primitive embryonic cells. It is rarer in adults, especially those over the age of 40. Adult ETMH occurring in the supratentorial region is extremely rare and has atypical radiology manifestations. The present study reported a case of adult supratentorial ETMH misdiagnosed as glioblastoma preoperatively. By summarizing its clinical features, radiological manifestations, differential diagnosis, and treatment and reviewing relevant literature, the present study aimed to improve the understanding of the diagnosis and treatment of adult supratentorial ETMH.
