Abstract:
Objective To evaluate the CT features and its diagnostic value in tuberculous meningitis(TBM).Methods Forty patients who had clinically proved TBM and each was performed with CT scans and enhanced CT were retrospective studied.Results CT scans showed abnormalities consistent with TBM in 36 cases(90%) whereas others(4 cases)were normal.Abnormalities were visualized on CT scans included basal exudate in 22 cases,hydrocephalus 36 cases,infarcts 11 cases and tuberculomas 9 cases.Conclusion The most characteristic findings with TBM are exudates in the basal cisterns and Sylvian fissures.It is essential in studying CT scans of TBM to make a note of the associated changes such as hydrocephalus,infarction and tuberculomas.These factors have a bearing on the plan of treatment.Surgical intervention should be considered after a conservative treatment if the tuberculoma consistent exists,or progressive ventricular enlargement are identified on CT.
