First case report of tuberculous meningitis secondary to endometrial tuberculosis following a clandestine abortion.

Tuberculous meningitis (TBM) is a medical emergency: it is the most severe, lethal and disabling clinical form of tuberculosis. We report the case of a 44-year-old woman who had undergone a clandestine abortion six weeks before admission. One week later, she had abnormal vaginal discharge. Three weeks prior to admission, headache, hyperpyrexia and mental alteration were added. At admission, a transvaginal ultrasound showed abnormalities of the uterine cavity. Sepsis and endometritis were diagnosed, and a hysterectomy was scheduled. During preoperative evaluation, meningeal signs were found. The first lumbar puncture (LP) showed a lymphomononuclear pleocytosis, hypoglycorrhachia and hyperproteinorrachia. After five days treatment with ceftriaxone, vancomycin and dexamethasone, only partial recovery occurred. A second LP showed AFB and PCR confirmed Mycobacterium tuberculosis. The histopathology of endometrial biopsy confirmed endometrial tuberculosis. Therapeutic response to anti-tuberculous treatment and corticosteroids was excellent. No other cause of immunosuppression apart from pregnancy was found. To the best of our knowledge, this is the first report of TBM secondary to endometrial tuberculosis and highlights an unusual clinical scenario in which severe and disseminated forms of TB could be present. TBM during and after pregnancy is rare, but compared with TBM in non-pregnant women, it has a poorer prognosis. Early diagnosis and treatment can be lifesaving in this life-threatening disease.
