Brain magnetic resonance imaging of a 28-year-old woman with stage 2 tubercular meningitis and vasculitis. (a and b) Diffusion-weighted images show acute infarct (both perforators and cortical branches) in the left middle cerebral artery (MCA) territory involving the centrum semiovale, putamen (ischemic zone) and frontotemporal region. (c) Axial T1 postcontrast image shows basal leptomeningeal enhancement predominantly in the left MCA region (circle) and multiple enhancing cerebral tuberculomas. (d) Three-dimensional time-of-flight noncontrast angiogram shows luminal narrowing of the left MCA with attenuated distal cortical branches and luminal narrowing of the anterior cerebral artery-A1 segment (circle).
