title: Endoscopic biopsy of a B-cell lymphoma involving the entire ventricular system: A case report.
abstract: A 62-year-old male suffering from vomiting and mild preceding nausea for 15 days was examined in the present case report. Magnetic resonance imaging revealed a homogeneously enhancing cluster-like lesion involving the lateral, third and fourth ventricles. An endoscopic biopsy was performed, and histopathological examination led to the diagnosis of a high-grade diffuse large B-cell lymphoma. To the best of our knowledge, the present study reports the first case of a primary lymphoma involving the entire ventricular system. Therefore, primary lymphomas should be considered in the list of ventricular tumors. An endoscopic biopsy requires minimal invasion to obtain an adequate tissue sample, and frequently leads to the correct diagnosis and subsequent treatment protocols.
