Gastric diffuse large B cell lymphoma presenting as paraneoplastic cerebellar degeneration: Case report and review of literature

Paraneoplastic cerebellar degeneration (PCD) is a type of paraneoplastic neurological disorder (PND) that is associated with many solid tumors, Hodgkin’s lymphoma (HL) and very rarely with non-Hodgkin’s lymphoma (NHL). We report a case of PCD associated with gastric diffuse large B-cell lymphoma (DLBCL) in a patient who presented with acute onset of giddiness and double vision and had complete remission of the gastric lesion and marked improvement of cerebellar syndrome with rituximab-based combination chemotherapy. A brief review of the literature is also presented.
