Parvovirus B19 infection associated with encephalitis in a patient suffering from malignant lymphoma.

A parvovirus B19 infection was established in a 58-year-old woman undergoing treatment for malignant lymphoma. Clinically, the patient displayed a variety of neurologic symptoms that could not readily be explained by the mere presence of lymphoblastic cells within the central nervous system. This is the first time parvovirus B19 DNA has been detected in the cerebrospinal fluid of a patient suffering from encephalitis.
