Primary central nervous system lymphoma revealed by multiple intraventricular mass lesions
A 71-year-old man was admitted in our institution with a 1-month history of vertigo, vomiting, and weight loss. He had no relevant medical history. On admission, the patient was significantly disoriented and we observed a severe impairment of short-term memory. He was able to walk without aid. He needed help to wash and get dressed. Cranial nerves, motor, sensory, and cerebellar examination was normal.
Blood tests including basic metabolic panel, liver function panel, thyroid studies, markers of inflammation, vitamin B12, and folate were all normal, and infectious serum tests including HIV were negative. The patient had no immunodeficiency. He underwent contrast-enhanced brain magnetic resonance imaging (MRI) demonstrating multiple homogeneously enhancing intraventricular mass lesions, involving the whole ventricular system (Fig. 1). Cerebrospinal fluid (CSF) analysis showed lymphocytic pleocytosis (115 cells/mm³; N ≤ 5) with increased protein (5.6 g/l; N: 15–45) and...
