Contrast enhancement of cerebellar infarction on computed tomography

The author analyzed the appearance on computed tomography after infusion of contrast medium of cerebellar infarction in three patients, whose diagnosis was made on the basis of clinical presentation, cerebral angiography, and sequential computed tomographic scans. Their computed tomographic appearance was not always the same as seen in the supratentorial counterpart, in showing reminiscence of an arteriovenous malformation, a leptomeningeal dissemination of a tumor or meningitis, or a neoplasm, respectively. For these reasons, it was concluded that it is important to notice the contrast-enhanced computed tomographic appearance in cerebellar infarction, when making a differential diagnosis between various pathologies in the posterior fossa.
