患者,男性,32岁,于1996年12月10日因左额脑瘤二次术后而第三次入院。患者于四年前曾因发作头痛9年半间断性抽搐2年而来我科就诊。当时神经系统查体无阳性体征,而头部CT发现左额叶内有2×3.5×3cm大小低密度病变;MRI左额病灶呈长T1长T2信号强度不均。诊断为左额星形细胞瘤而于1992年10月23日在全麻下经左额入路行左额部肿瘤肉眼全切术。术中见肿瘤实质性,约2×3.5×3cm大小,血运不丰富。切除后的标本镜下观察可见星形胶质细胞核圆形或卵圆形,大小较一致,很少见到胞浆,核染色质均匀,瘤细胞弥漫排列,较正常脑胶质细胞分布略密,未见核分裂,此外可见少量薄壁血管,无
The patient, male, 32 years old, was admitted to hospital for the third time on December 10, 1996 for a second postoperative left brain tumor. Four years ago, the patient was treated for headache for 9 and a half years due to intermittent seizures for 2 years. Neurological examination was no positive signs at the time, while the head CT found in the left frontal lobe with 2 × 3.5 × 3cm size of low density lesions; MRI left forehead lesions were long T1 long T2 signal intensity uneven. Diagnosis of left frontal astrocytoma and on October 23, 1992 under general anesthesia by the left frontal line total left eye tumor macroscopic excision. See intraoperative tumor substantive, about 2 × 3.5 × 3cm size, blood supply is not rich. Microscopically, the astrocytes showed round or oval nucleus after resection. The size of the astrocytes was more uniform than that of the astrocytes. The cytoplasm was rare, the chromatin was uniform, and the tumor cells were arranged diffusely, slightly more than normal glial cells , No nuclear fission, in addition to a small amount of visible thin-walled vessels, no
