Intracranial tuberculosis in children: CT appearance and clinical outcome.
We retrospectively evaluated the CT studies of 9 children who presented with intracranial tuberculosis during 1981-1987, and compared their radiographic appearance with the clinical outcome. The most common radiographic findings were: 1) ventriculomegaly (7/9) ,2) tuberculoma formation (6/9), and 3) infarction (4/9). Of 7 patients with ventriculomegaly, 3 required a ventricular shunt and 2 had spontaneous resolution of ventricular dilatation. Four children with ventriculomegaly were moderately or severely retarded, one had cognitive dysfunction, and one was neurologically normal. Four of six children with tuberculoma also had infarction and/or ventriculomegaly; of these four children, three were moderately or severely retarded. Two patients with tuberculoma as the only intracranial abnormality had complete resolution of the granuloma with normal neurologic outcome following antituberculous therapy. The four children with large vessel infarction also had ventriculomegaly; three had poor clinical outcome. The presence of tuberculoma alone is not necessarily predictive of poor neurologic outcome; age less than 20 months, infarct, and/or ventriculomegaly are usually associated with sequelae.
