A case of germinoma originating in the basal ganglia is presented. Preoperative MRI showed an area of a reticulated core of mixed signal intensity with a surrounding rim of low signal intensity in the right basal ganglia on T2-weighted image. This finding was reported to be characteristic of cavernous angioma, but the tumor was histopathologically identified to be a germinoma with old hemorrhage. The pitfall of MRI in diagnosing brain tumors is discussed.
