Correlation between Sex Hormone Binding and Peritumoral Edema in Intracranial Meningiomas

Abstract: Estrogen and progesterone receptor binding activity was measured in 22 intracranial meningioma surgical specimens. None of the tumors was estrogen receptor-positive, whereas 19 were progesterone receptor-positive. Of these 19 patients, all demonstrated significant computed tomographic (CT) evidence of peritumoral edema. None of the 3 patients who lacked progesterone receptor binding had CT evidence of peritumoral edema (P less than 0.005). Peritumoral edema associated with intracranial meningiomas seems to be … Show more

“…A frequência de edema perilesional em meningiomas descrita na literatura é variável (de 17 a 92%) [10][11][12] , com a maioria das séries referindo entre 40 a 80% dos tumores (Tabela 3). Essa grande diferença entre os diversos estudos provavelmente relaciona-se aos critérios adotados para considerar a presença de edema perilesional significativo.…”

“…Em outras séries, não foi estabelecida relação entre o tamanho dos meningiomas e edema peritumoral 12,16,19 . O crescimento do meningioma pode levar à compressão do parênquima adjacente produzindo isquemia local e compressão das veias de drenagem 10,22 .…”

“…23,30 Some authors, however, have reported increased edema in angioblastic and meningothelial meningiomas. 11,23,27,[30][31][32] The most important contributing factor of peritumoral edema is based on the attenuation of the vascular network present in the tumor. 11,23 In our study, calcification was not a dominant feature in RM.…”

“…The pathophysiologic mechanisms at the base of its formation 1,2 are related to ischemia caused by compression of the tumor, 3 stasis followed by venous congestion, 4 and excretory-secretory phenomena. [5][6][7][8] Although the pathogenesis of the edema differs according to whether the tumor is intraaxial or extra-axial, ultrastructural studies have shown that, in both cases, the edema is vasogenic. 9 The advent of functional MR techniques such as diffusion and perfusion imaging and spectroscopy has opened the door to in vivo dynamic and metabolic assessments.…”
