Central nervous system germ cell tumor is a rare intracranial tumor lesion, accounting for 2% to 3% of all pediatric tumors. Due to its high sensitivity to radiotherapy and chemotherapy, early and accurate diagnosis and timely treatment are crucial for patient prognosis. The vast majority of patients can achieve clinical cure without surgery. Intracranial germ cell tumors are more common in the pineal region, suprasellar region, basal ganglia region, and other areas, and have certain characteristics in terms of age, gender, clinical manifestations, and imaging manifestations. This article summarizes the clinical and imaging features of intracranial germ cell tumors in order to further enhance the understanding of the disease among physicians.
