A 59-year-old man with a history of abdominal non-Hodgkin lymphoma (NHL) was admitted for a slowly progressing confusional state and mood alterations. After radiation therapy for a relapse of abdominal NHL 2 years previously, adjuvant therapy with interferon alfa had been initiated.
On admission, the patient was disoriented to time and place and displayed psychomotor retardation and symptoms of depression. Otherwise, the results of neurologic examination were unremarkable, as were findings from an extensive laboratory workup for metabolic or toxic encephalopathy. Results of repeated cerebrospinal fluid studies were normal and not indicative of meningeal infiltration of NHL or encephalitis.
