case_images: Brain magnetic resonance imaging (MRI) showed a cerebellar mass measuring 45 x 50 mm. The mass was hypointense on T1W sequence (a), hyper- and iso-intense on T2W sequence (b), and was heterogeneously enhanced on T1W postgadolinium (c).

case_images: Brain magnetic resonance imaging (MRI) showed a cerebellar mass measuring 45x50 millimeters [Figure 1].
case_images: The brain and spine MRI follow-ups showed no tumor remnant and metastasis at 1-year. 2-year, 3-year posttreatment.

case_images: The postoperative MRI of the brain and spine showed no tumor remnant and metastasis [Figure 2].
case_images: After a 4-year follow-up, brain computed tomography (a) illustrated a temporal mass, which was hyperdense on computed tomography. On MRI, it enhanced heterogeneously on T1W postgadolinium (b) and hyperintense on T2W sequence (c).

case_images: T1W sequence, hyperintense on T2W sequence, and enhanced heterogeneously on T1W postgadolinium [Figure 3]. The spine MRI showed no metastasis lesion.
case_images: The histopathological examination revealed germinoma. The immunohistochemistry staining was CD117 (+), PLAP (+), Ki67 (+), beta-hCG (-), AFP (-), LCA (-), S100 (-), Synaph (-), GFAP (-), and CK (-).

case_images: AFP (-), LCA (-), S100 (-), Synaph (-), GFAP (-), and CK (-) [Figure 4]. After that, the patient received 24 Gy CSI with a 16 Gy boost to the temporal region.
case_images: The 1-month (a), 6-month (b), and 1-year (c) postoperative MRI showed no tumor remnant.
