The clinical features, etiology, and neurological outcome in patients with primary intraventricular hemorrhage (PIVH) have rarely been reported. We retrospectively reviewed the clinical data, complementary examinations, outcome, computed tomography (CT) blood amount, and ventricle size of 13 patients (mean age 60 years, five men). We defined PIVH as hemorrhage detected by CT in the ventricular system only. The major symptoms included headache (n = 13), decreased level of consciousness (n = 9), and nausea/vomiting (n = 7). The cause was unknown in five patients; and was associated with arterial hypertension in five, vascular malformations in two, and tumor in one, although arteriography was performed in only five patients. Outcomes were death in three, asymptomatic in six, mild disability in three, and moderate disability in one. Prognosis was not related to clinical or CT data. Clinical features can suggest the diagnosis of PIVH, but cerebral CT is required for confirmation.

These results indicate that patients with basal ganglia calcifications frequently have a subcortical pattern of neuropsychological dysfunction and behavioral changes that are known to be associated with alterations of the frontal-limbic-basal ganglia circuits. The pattern of neuropsychological impairment is consistent with basal ganglia damage. However, poor performance in other neuropsychological tests suggest additional involvement of other connected networks.

The PI of the unaffected hemisphere may be a predictor of death in acute ICH. These findings suggest that intracranial hypertension is the most likely cause of death in most patients with ICH.

We describe 5 patients with vertebral haemangiomas treated by radiotherapy of 30-40 Gy, 2-3 Gy/day. The management of vertebral haemangiomas is discussed.
