Clinicoradiologic Profile and Outcome of Children With Tubercular Meningitis in a Tertiary Care Hospital in Bangladesh.

BACKGROUND

Children are most vulnerable to tubercular meningitis. Neuroimaging is an important initial investigation in tubercular meningitis.

OBJECTIVE

This study was done to describe the clinical profile, neuroimaging changes, and clinical outcome in children with tubercular meningitis.

METHODOLOGY: This was an observational cohort study on children with tubercular meningitis, between January 2012 and June 2018. Tubercular meningitis was diagnosed on the basis of clinical criteria, cerebrospinal fluid analysis, neuroimaging, and response to antitubercular drug treatment. Preferably magnetic resonance imaging (MRI) with contrast was done.

RESULT: Out of 79 pediatric patients, 17 patients were lost during follow-up; thus, a total of 62 patients were studied. Mean age at presentation was 7.040 (±3.99 SD) year, 51.6% children were male. Rural children were more affected. Twenty eight (45.2 patients had contact with a person with tuberculosis. Only 3 (4.8%) patients presented within 10 days of duration of illness. Most of the cases (67.7%) were in stage 2 at the time of diagnosis. The most common clinical feature was fever, seizure, and signs of meningeal irritation (all present in 12.9%). In neuroimaging most common findings were tuberculoma (50%), hydrocephalus (54.8%), and basal meningeal enhancement (33.8%). Regarding outcome, 6 (9.67%) patients expired and 47 (75%) patients had sequelae. The most common complications were hydrocephalus (30.64%) and intellectual disability (12.9 ). Hydrocephalus was the most common neuroimaging finding among the patients who expired (33%).

CONCLUSION

Hydrocephalus is the most common neuroimaging finding. Normal neuroimaging is associated with good outcome whereas all the patients who died had abnormal neuroimaging.
