A case of tuberculosis meningitis after allogeneic hematopoietic stem cell transplantation for relapsed Acute Myeloid Leukemia.

We report a case of tuberculosis (TB) meningitis after allogeneic hematopoietic stem cell transplantation (HSCT) for relapsed acute myeloid leukemia. The patient was 52‐year‐old woman who had relapsed leukemia with a remission duration of 7 months, and she received re‐induction with consolidation, allogeneic HSCT. After 4 days of engraftment, she had headache with fever and cerebrospinal fluid (CSF) analysis presented increased intracerebral pressure, white blood cell counts with dominant neutrophils, elevated glucose and protein level. Brain imaging showed diffuse leptomeningeal enhancement with scattered miliary TB lesions suggesting disseminated TB disease. Mycobacterium tuberculosis was detected in CSF and sputum anti‐TB medication was started. She was IGRA positive before transplantation but did not receive treatment for LTBI prior or during the transplant. Unfortunately, she expired because of intracerebral hemorrhage. TB meningitis is a rare but important complication of HSCT as it can cause serious neurologic sequelae, even death. So in transplant recipients having high risk of TB reactivation, LTBI treatment is recommended before or along with transplantation. If latent TB is not treated, vigilant suspicion and early diagnosis of TB meningitis could improve the transplant outcome. [ABSTRACT FROM AUTHOR]
