A case of germinoma in the septum pellucidum manifesting as amnesia and hemiparesis.
BACKGROUND
We report a rare case of germinoma mainly located in the septum pellucidum.


METHODS
A 19-year-old man presented with germinoma located in the septum pellucidum manifesting as amnesia and right hemiparesis. Magnetic resonance imaging demonstrated a heterogeneously enhanced mass in the septum pellucidum and abnormal T2-weighted signals in the left basal ganglia. An anterior transcallosal approach was performed to remove the mass in the septum pellucidum. The histological diagnosis was germinoma. Radiotherapy and chemotherapy were given. He was discharged with slight amnesia and right hemipareis.


CONCLUSIONS
Intracranial germinoma can arise from the septum pellucidum.
