Overview of radiological and anatomical pathology of meningioma disease: a 3-year retrospective study

Abstract

BACKGROUND: Meningioma is a benign tumor of the meninges. It is the most common primary brain tumor in adults. The incidence in Indonesia is around 36% among brain tumor patients. It occurs often in women, and the incidence increases with age. Radiological imaging and histopathology of meningioma are very important to determine the incidence for epidemiological study. This study aimed to determine the demographic, histopathological, and radiological findings characteristic of meningioma at Dr. Wahidin Sudirohusodo Hospital, Makassar, Indonesia.METHODS: This was a descriptive study with retrospective analysis of data from 146 meningioma patients. Meningioma was diagnosed using physical examination, anatomical pathological tissue examination, and computed tomography imaging. Demographic characteristics, histopathological examination, and radiological imaging were assessed using hospital medical records.RESULTS: A total of 146 patients were diagnosed with meningiomas. The meningiomas were found more frequently in women (76%) and most often in the 41-to-50-year-old group (44%). The most frequent intracranial tumor locations were in the parietal lobe. The most common radiological imaging was meningioma with single, well-defined, isodense density with high-contrast enhancement, sometimes with moderate cerebral edema.CONCLUSIONS: The most common density type of meningioma was isodense. The majority of meningioma patients were female. Most occurred intracranially, with a solitary or single appearance and firm boundaries. On a non-contrast CT scan, most tumors had an isodense appearance, and with contrast, a strong shock was obtained. Most were accompanied by moderate cerebral edema and hyperostosis.
