Surgical interventions for primary central nervous system lymphoma.
Early diagnosis is central to proper management of primary central nervous system lymphomas (PCNSLs). Surgical intervention hinges on initial entertainment of a diagnosis of a PCNSL, based on acute neurological presentation and neuroimaging findings. Unless there is an urgent need for surgical decompression, a biopsy to obtain a diagnosis of PCNSL is the first step in surgical management. Repeated biopsy may be necessary in patients who have received preoperative steroid therapy. Patients with PCNSL may also present with leptomeningeal involvement, resulting in the need for an Ommaya reservoir for intrathecal chemotherapy. In cases in which hydrocephalus develops, placement of a ventriculoperitoneal shunt may be necessary. Two case studies are presented to highlight the role of surgical intervention in PCNSL.
