Abstract
INTRODUCTION:Seizures are the initial clinical symptom in 30 to 50 % of patients with brain tumors. With a high percentage, gliomas and meningiomas have been reported as tumors associated with epilepsy, these also being frequent tumors in Colombia. Currently in the country there are no studies that specify which are the most frequent brain tumors related to epilepsy, an investigation being necessary to clarify these data.
OBJECTIVE:To determine the most frequent brain tumors associated with epilepsy in patients at the Erasmo Meoz University Hospital in Cúcuta.
METHODS:Medical records were collected from all patients over 18 years of age who were admitted to the Neurosurgery service of the Erasmo Meoz University Hospital in Cúcuta with a diagnosis of brain tumor between 2015 and 2018.
RESULTS:220 patients were included, 56% were female. The mean age was 48 years; 98 cases (45%) presented with epilepsy. The most frequent brain tumor related to epilepsy were gliomas (46 cases). The glioma with the highest frequency of seizures was glioblastoma (27 cases). Low-grade gliomas had a higher percentage of epilepsy (82%) than high-grade gliomas (71%). In men, the most frequent tumor related to epilepsy was glioblastoma and in women, meningioma. The most frequent location was the frontal region (27%).
CONCLUSIONS:Gliomas are the most common type of brain tumor associated with epilepsy, with the most common tumor in this group being glioblastoma.
