A Rare Cause of Encephalopathy Post Renal Transplant: BK Polyoma Virus Encephalitis.

BK polyoma virus (BKV) belongs to Polyomaviridae family. It is a double-stranded DNA virus. Only a few cases of BKV-associated neurological disease in renal transplant recipients have been reported. BKV related central nervous system (CNS) infection may often remain unrecognized in immunocompromised patients. Here, we are reporting a case of BKV encephalitis post renal transplantation for the awareness of all physicians regarding this entity.
