case_images: Preoperative images. (a) Sagittal T2 image demonstrating a heterogeneous posterior fossa lesion with compression of the cerebellum and enlargement of the supratentorial ventricles. (b) Contrast-enhanced axial T1 image of the posterior fossa lesion demonstrating avid contrast enhancement. (c) Axial T2 MRI showing significant heterogeneity within the lesion with effacement of the fourth ventricle

case_images: Magnetic resonance imaging (MRI) was obtained, which revealed a very large dural-based extraaxial mass along the dorsal aspect of the posterior fossa [Figure 1].
