Evaluation of cerebral arterial and venous system in tuberculous meningitis (original) (raw)

Central nervous system infection especially pyogenic results in cerebral venous sinus thrombosis. Tuberculous meningitis (TBM) although associated with infarctions but there is no comprehensive study evaluating the role of CVST contributing in infarction PURPOSE: To evaluate cerebral arterial and venous system using MR angiography (MRA) and MR venography (MRV) in TBM, and correlate with clinical and MRI findings. Consecutive patients with TBM were evaluated clinically and their consciousness was assessed by using Glasgow Coma scale.Cerebrospinal fluid analysis was done. Patients were subjected to MRI, MRA and MRV studies.The severity of TBM was categorized as grade I to III. Presence of infarction on MRI and its cause as arterial or venous was noted based on MRA and MRV abnormalities. 26 patients were included whose median age was 23 years. 7(26.9%) patients had stage I, 12 (46.2%) stage II and 7 (26.9%) stage III TBM. MRI revealed infarction in 13(50%) patients and were in tubercul...
