Radiological features of germinoma arising from atypical locations - Three case reports

Abstract

Three cases of intracranial germinoma arising from atypical locations occurred in 13-, 22-, and 28-year-old males. The location of the tumor was the corpus callosum (2 cases) and the temporal lobe. Computed tomography and magnetic resonance imaging showed all three tumors had a largest dimension, including the internal cyst, of over 6 cm, and the cysts were larger than 2.5 cm. Radiotherapy and chemotherapy caused all tumors to disappear. Large tumor and large cyst are features of germinoma arising from atypical locations.
