Tuberculous meningitis manifesting with neuroregression in a eleven month child.

Tuberculosis (TB) is a disease of diverse manifestations. In children, neurotuberculosis is the severest form, which when left untreated can have deleterious consequences. There has been reports on pediatric TB meningitis manifesting with fever and seizures, altered sensorium or focal deficits. There are reports on TB meningitis presenting with cognitive decline in adults. We are reporting a eleven month old girl child who presented with acute regression of attained developmental milestones of one month duration as the only presenting complaint and MRI brain revealed basal exudates with hydrocephalus which nailed the diagnosis of tuberculous meningitis. CSF (Cerebro Spinal Fluid) tested by CBNAAT (Cartridge Based Nucleic Acid Amplification Testing) for TB was negative, but gastric aspirate tested for the same, came positive. Tuberculin skin testing was also positive. Chest X-ray was normal. The child had not received BCG (Bacillus Calmette Guerin)vaccine, thereby increasing her risk of complicated TB. The contact couldn't be traced. The child was started on ATT (Anti Tubercular Treatment) as soon as the diagnosis was made and she improved, thus signifying the better outcome with early initiation of ATT. This case reporting is intended to highlight the unusual presentation of TB meningitis in children, which when clinicians are aware of will lead to early treatment and better prognosis.
