Apart from T2-weighted imaging, T1-weighted imaging (T1WI), diffusion-weighted imaging, susceptibility-weighted imaging, fluid-attenuated inversion recovery, and postcontrast T1WI, time-of-flight (TOF) MRA and postcontrast MRV were done in all the patients. MRV was done after intravenous administration of gadolinium-based contrast agent followed by postcontrast T1WI. MRA and MRV findings were analyzed.<\/jats:p>\n<jats:p>\n<jats:bold>Results<\/jats:bold>\u2003Mean age of the patients was 33.13\u2009\u00b1\u200914.93 years. Duration of symptom was 34.90\u2009\u00b1\u200933.82 (range: 10\u2013150) days. Out of 30 patients, 11 were categorized as definite TBM and 19 probable TBM. Eighteen (60%) were grade I, 7 (23%) grade II, and 5 (16%) grade III TBM based on severity. MR abnormalities were in varying combinations of leptomeningeal enhancement in 24 (80%), pachymeningeal in 2, both in 3, tuberculomas in 13 (43.3%), ventriculitis in 1, hydrocephalus in 16 (53.3%), and infarcts in 10 (33.3%) patients out of which the tubercular zone infarct in 9 patients. TOF MRA showed arterial abnormality in 13 patients. Anterior cerebral artery and middle cerebral artery have commonly involved vessels. Dural sinus thrombosis was noted in two patients. Both were female. One patient had subacute thrombus in the posterior part of superior sagittal sinus, left transverse sinus, and proximal right transverse sinus. The second patient had a filling defect in the transverse sinus.<\/jats:p>\n<jats:p>\n<jats:bold>Conclusion<\/jats:bold>\u2003In TBM, there is predominant arterial involvement causing infarcts which are usually seen in the tubercular zone. However, occasionally, there may be venous involvement causing cerebral venous sinus thrombosis.<\/jats:p>","DOI":"10.1055\/s-0042-1748175","type":"journal-article","created":{"date-parts":[[2022,6,8]],"date-time":"2022-06-08T22:52:36Z","timestamp":1654728756000},"page":"529-536","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Vascular
