Oligodendroglioma cístico e positividade das reações para cisticercose relato de caso

Abstract

A case of a 32-year old male patient with complaints of frontal headache progressive decrease in visual acuity, altered behaviour, and positive results of immunological tests for cysticercosis performed on the cystic and cerebrospinal fluids is presented. After several clinical and surgical proceedings, the frontal craniotomy was indicated and a multi-lobulated cystic tumor was excised. Biopsy material revealed an oligodendroglioma invading the degenerated membrane of cystic wall. Some aspects related to the possible mechanisms involved in the association of oligodendroglioma with neurocysticercosis in the presented case are discussed. Three different types of conclusions may be reached: (1) neurocysticercosis may have acted as an oncogenetic factor for the oligodendroglioma; (2) the glycoprotein nature of the antigens of gliomas and cysticercosis and the similarity in the molecular weight range of their polypeptides may be responsible for the positivity of the reactions for cysticercosis in the cystic fluid; or (3) the association of oligodendroglioma with cysticercosis may be a simple coincidence. The present study strengthens the opinion that other pathologies should be looked for when clinical treatment of cysticercosis does not follow the expected course.

Association between Cysticercosis and Neoplasia: A Study Based on Autopsy Findings

“…Cysticercosis is a chronic parasitic inflammatory disease caused by the larval form of the Taenia solium parasite that elicits inflammatory reactions in both the tissues surrounding the parasite and distant tissues [ 1 , 2 ]. Cysticercosis is prevalent in several regions of Asia, Africa, and Latin America owing to poor sanitary conditions and socioeconomic conditions [ 3 , 4 ].…”
