Letter to the Editor

Dear Editor,

Progressive multifocal leukoencephalopathy (PML) is a severe demyelinating disease of the central nervous system (CNS), fatal in some cases, and JC virus (JCV) is the usual cause [1].

BK virus (BKV) is a ubiquitous virus and its primary infection is generally asymptomatic. It occurs in childhood [2] and, as well as JCV, belongs to the Polyomaviridae family. Both viruses are associated with a clinical disease in the setting of immunosuppression: JCV commonly in association with PML, while BKV with nephropathy and hemorrhagic cystitis [2].

Here we report a rare case of BKV-associated PML in a patient with systemic lupus erythematosus (SLE).

Case report

A 60-year-old female, with a history of SLE since the age of 40 (on treatment with azatioprine and medrol for 2 years), developed a confusional state, weakness of lower extremities and personality change. She was admitted to the neurology department and underwent brain MRI (Fig.  1 )showing findings highly consistent with PML....
