Tuberculous peritonitis complicated by immunologic cerebral vasculitis.

A 53-year-old female was admitted with ascites for 3 weeks, decreased response, and weakness of right upper and lower limbs for 1 day. Peritoneal biopsy showed necrotizing granulomatous inflammation, and cartridge-based nucleic acid amplification test for tuberculosis (TB) of biopsy was positive without rifampicin resistance. Magnetic resonance imaging brain showed multiple foci of diffusion restriction in bilateral cerebral hemisphere and cerebellum, suggestive of acute infarcts. After ruling out the secondary causes of cerebral infarction by appropriate tests and demonstrating that there was no evidence for tuberculous meningitis or direct injury, it was concluded that the reason for multiple cerebral infarctions in this patient is likely to be immunologic injury secondary to TB. Multiple cerebral infarctions secondary to immunologic injury in TB were reported only once previously.
