鞍上-脚间池肿瘤较少见,手术切除较困难。自1990年以来我们均经额下-翼点入路在手术显微镜下切除肿瘤4例,效果满意,报告如下。 1 临床资料 4例中男3例,女1例,年龄25～56岁。其中颅咽管瘤3例,脊索瘤1例。1例女性病人以停经、泌乳入院;3例男性病人均以视力障碍入院。4例均行CT和MRI检查,肿瘤直径3～7Cm。CT扫描可见肿瘤为混合密度影,边界清晰,肿瘤自后床突向后生长,直达脚间池。MRI在3例实体肿瘤可见混合信号,1例囊性肿瘤除混合信号外,瘤囊的T1为等信号,T2为高信号。MRI可清楚地显示肿瘤的部位和周围结构的关系,对肿瘤的切
Saddle - foot pool cancer is rare, surgical removal more difficult. Since 1990, we have undergone forehead-wing point approach under the surgical microscope to remove the tumor in 4 cases, the results are satisfactory, the report is as follows. 1 clinical data in 4 cases, 3 males and 1 female, aged 25 to 56 years. Among them, 3 cases were craniopharyngioma and 1 case was chordoma. One female patient was admitted to hospital for menopause and lactation. Three male patients were admitted with visual impairment. 4 patients underwent CT and MRI examination, tumor diameter 3 ~ 7Cm. CT scan shows mixed density of tumor shadow, the boundary is clear, the tumor from the back of the bed sudden growth, direct access to the foot pool. MRI showed mixed signals in 3 cases of solid tumors, 1 case of cystic tumors in addition to the mixed signal, tumor capsule T1 is equal signal, T2 is high signal. MRI can clearly show the relationship between the tumor site and the surrounding structure, the tumor cut
