Angiography of cerebellar hemorrhage secondary to hypertension

In a patient with cerebellar hemorrhage due to hypertension, deterioration may be so rapid there is not sufficient time for radiographic studies prior to craniectomy. In the less critically ill patient, posterior fossa angiography is the procedure of choice and is highly accurate in localizing the mass lesion. Angiography is particularly helpful in the patient with an atypical presentation because an etiology of the hemorrhage other than hypertension may be demonstrated.

Cerebellar ectopia presenting in adult life

Three cases of cerebellar ectopia first producing symptoms in adult life are reported. This potentially remediable anomaly may not be suspected in adults, in whom associated congenital bony abnormalities of the skull and cervical spine are often absent. In these cases diagnosis depends on radiological contrast studies; in particular it is important to examine the cervical canal in the prone and supine positions.
