【摘要】 观察46例证实的婴、幼儿结核性脑膜炎,对照临床病程分析各种CT表现的范围、积水程度以及随访所见。CT表现为脑积水、脑萎缩、脑膜结核瘤、边缘带反应、脑梗塞。后遗症包括脑积水、局限脑软化灶、脑膜钙化。脑积水是幼儿结核性脑膜炎最早的异常表现,通常先于基底池消失几周,脑积水积度与病程持续时间呈正比,与年龄大小呈反比,中、重度脑积水提示预后差。脑基底池血管周围毛刺状或串珠强化影,预示着脑梗塞的可能。更多还原

【Abstract】 Forty-six cases of tuberculous (TB) meningitis in childhood were examined regularly with CT during their hospitalization, and the CT imagings wer.e investigated and compared with clinical progression. The major pathological changes showed by CT imaging included hydrocephalus cerebral atrophy ,tuberculomas and cerebral infarction. The sequelae of TB meningitis included hydrocephalus, focal softening of brain and meningeal calcification. Hydrocephalus is the first abnormal manifestation and may precede the obliteratien of basilar cisterns by several weeks. The degree of ventriculomegaly associated with TB meningitis is directly related to the duration of the illness and inversely related to patient’s age. Hydrocephalus patients usually have poor outcome. Perivascular spiculated enhancement in the basal cisterns suggests perivascular inflammation and may predict subsequent infarction.更多还原
