Intracranial Capillary Hemangioma in the Posterior Fossa of an Adult Male

Figure 2

Axial (a) and coronal (b) CT angiography (CTA) of the head in the arterial phase demonstrates unchanged hemorrhage in the region inferior right cerebellar peduncle, likely intraparenchymal, with extension into the fourth ventricle without evidence of aneurysm or vascular malformation. The right posterior inferior cerebellar artery (PICA) is not well seen (arrow in (b) indicates the normal left PICA) and may be compressed by surrounding hemorrhage, involved with vasospasm or thrombosed.
