Ischemic infarction in 25 children with tuberculous meningitis.

Abstract

Twenty-five cases (38%) of ischemic infarction occurred among 65 cases of tuberculous meningitis in patients less than 14 years of age. The male:female ratio was 1.3:1. The most frequent clinical findings were meningeal signs, fever, alteration of consciousness, cranial nerve involvement, seizures, and focal neurologic deficit. Twenty-three patients had anterior circulation infarcts, and two more had infarcts in the vertebrobasilar territories. Distribution of infarcts in the anterior circulation was shown by computed tomography in the territories of the following arteries: lenticulostriate, 10 cases unilateral and 6 bilateral; middle cerebral, 3 cases; internal carotid, 1 case; multiple areas, 3 cases. Of the 25 ischemic infarction cases, 23 (92%) had hydrocephalus, 19 (76%) basal exudates, and 2 (8%) tuberculomas. Outcome was poor since no patient with infarction recovered completely. Six died and bilateral subcortical infarcts led to a considerably higher mortality than unilateral ones, whether cortical or subcortical.
