Axial non-contrast
Axial bone window

Sagittal C+ delayed
Non-contrast computed tomography (NCCT) images demonstrate a heterogeneous mass with dural attachment in the posterior fossa which causes obstructive hydrocephaly. In the bone window, the lesion erodes the skull base.
Contrast-enhanced CT (CECT) demonstrates heterogeneous enhancement and vascular structures within the lesion.
