Expert Opinion :
This child has been having fever on and off for the past 4 months with now continuous fever for the past 1 month. During those episodes of fever, she has had 2 episodes of convulsion which were labeled as febrile convulsion. Before diagnosing febrile convulsion (which is a diagnosis of exclusion), it is necessary to rule out other causes of fever and convulsion such as meningitis, brain abscess, and SOL. In this child, lumbar puncture showed 64 cells (10% polymorphs, 90% lymphocytes with normal sugar and protein suggestive of partially treated meningitis. Her CT brain was normal. Thus, this child had meningitis which was mistaken as febrile convulsion. The lesson is that every convulsion with persistent fever may warrant a CSF examination to rule out meningitis as one may miss the same clinically which may be detrimental in the long run.
