Space occupying lesion of brain: An unusual site for a common infection.

Filariasis is a public health menace and is a cause for concern due to its endemicity in tropical and subtropical countries of Africa, Asia, and Western Pacific. Even in endemic areas, it is rare to find filariasis in fluid specimens especially cerebrospinal fluid. Herein, we report a case of unsuspected filarial parasitic infection in an adult male admitted as a case of space occupying lesion in brain with suspicion of lymphoma/granulomatous disease on the basis of clinicoradiological details. To the best of our knowledge, such an extensive brain involvement by filariasis has not been reported before.
