本文报告了146例幕上星形细胞瘤的CT 表现,并依病理分类情况分析了不同间变程度星形细胞瘤CT 所见,最后讨论了星形细胞瘤的鉴别诊断问题。幕上星形细胞瘤是一种侵润性生长的恶性肿瘤,好发于颞叶。病理上,肿瘤大体及镜下表现具有很大差异,这主要取决于细胞间变程度,细胞数量、新生血管、钙化及退行性变即囊变、出血和坏死等。 This article reports 146 cases of supratentorial astrocytoma CT manifestations, and according to the pathological classification of different degrees of ascites CT findings, and finally discussed the differential diagnosis of astrocytoma. Supratentorial astrocytoma is a invasive growth of malignant tumors occur in the temporal lobe. Pathologically, the gross and microscopic appearance of tumors varies widely depending on the degree of intercellular change, cell number, neovascularization, calcifications and degenerative changes, ie, cystic degeneration, hemorrhage and necrosis.
