【摘要】:顱內(nèi)皮樣囊腫是一種少見的先天性良性腫瘤,其臨床表現(xiàn)取決于病灶的位置、大小、生長速度、有無破裂與感染等,無特征性癥狀/體征。典型的皮樣囊腫在CT上表現(xiàn)為邊界清楚的低密度影,CT值多為負(fù)值,周圍水腫缺如,在MRI上,T1、T2加權(quán)以高信號為主,囊腫多不被增強(qiáng),而囊壁可有條索狀強(qiáng)化。確診需行病理學(xué)檢查。治療首選開顱顯微鏡下手術(shù)切除。大多數(shù)患者預(yù)后良好,但也可復(fù)發(fā)、惡變、并發(fā)無菌性腦膜炎和腦積水,所有患者都應(yīng)長期隨訪。
[Abstract]:Intracranial dermoid cyst is a rare congenital benign tumor. Its clinical manifestation depends on the location, size, growth rate, rupture and infection of the lesion, and has no characteristic symptoms / signs. On CT, typical dermoid cysts showed low density with clear boundary, negative CT value and absent peripheral edema. On MRI, T _ 1 T _ 2 weighted images were mainly hyperintense, most cysts were not enhanced, and the cyst wall could be enhanced in stripe shape. Pathological examination is necessary for diagnosis. The first choice of treatment is craniotomy under the microscope. Most patients have a good prognosis, but can also relapse, malignant change, accompanied by aseptic meningitis and hydrocephalus, all patients should be followed up for a long time.
