Neurological and systemic complications of tuberculous meningitis and its treatment at Auckland City Hospital, New Zealand

Mortality and serious long-term sequelae still occur in about 50% of patients with tuberculous meningitis. The frequency and the clinical features of neurological and systemic complications were determined in a retrospective review of 104 patients with tuberculous meningitis. Complications occurred in 81 patients (78%). The most common complications were: hyponatraemia 49%, hydrocephalus 42%, stroke 33%, cranial nerve palsies 29%, epileptic seizures 28%, diabetes insipidus 6%, tuberculoma 3%, myeloradiculopathy 3% and hypothalamic syndrome 3%. The most common iatrogenic complication was hepatotoxicity related to anti-tuberculosis treatment in seven patients. Twenty-three patients (22%) died. At last follow-up one patient (1%) remained in a persistent vegetative state, 14 patients (13%) had severe disability and 12 patients (12%) were moderately disabled. The most common complications in the 81 long-term survivors were cognitive impairment (12%) and epilepsy (11%). Neurological and systemic complications of tuberculous meningitis were common and were important causes of mortality and long-term morbidity.
