Atypical presentation of tuberculous vasculitis: dual large vessel occlusions leading to malignant ischaemic stroke.

Tuberculosis (TB) is a significant global health challenge, particularly in developing countries. One rare complication of TB is vasculitis, involving inflammation of the blood vessels by TB vasculitis typically results from the haematogenous spread of bacteria to the cerebral vasculature or extension from adjacent tuberculous lesions, such as tuberculomas. The pathogenesis includes direct invasion of vessel walls, leading to inflammation, luminal narrowing, thrombosis and ischaemic brain damage.
