Venous angioma CT: No abnormality or small, slightly hyperdense zone prior to contrast administration. Contrast enhancement seen in a slightly prominent vein draining a collection of small veins. MRI: On postcontrast T1-weighted images, venous angiomas are seen as a gadolinium contrast-enhancing transcortical vein draining a collection of small medullary veins (caput medusae). The draining vein can be seen as a signal void on T2-weighted images. Considered an anomalous venous formation typically not associated with hemorrhage; usually an incidental finding except when associated with cavernous hemangioma.
High signal is seen on the axial T2-weighted MRI (b) and FLAIR MRI (c). ) Intra-axial lesions in the posterior cranial fossa (infratentorial) Lesions Medulloblastoma (primitive neuroectodermal tumor of the cerebellum) ▷Fig. 82a–d CT Findings Comments Juvenile pilocytic astrocytoma, subtype: CT: Solid/cystic focal lesion with low to intermediate attenuation, with contrast enhancement. ▷Fig. 80 MRI: Low to intermediate signal on T1-weighted images, high signal on T2-weighted images, usually with prominent gadolinium contrast enhancement.
