It is believed that in the diagnosis of the intracranial tumor, the different characteristics of CT features in the same intracranial tumor must be grasped besides the general characters of the different intracranial tumor.

The CT features of 100 cases of the intracranial tumor are analysed. It is believed that in the diagnosis of the intracranial tumor, the different characteristics of CT features in the same intracranial tumor must be grasped besides the general characters of the different intracranial tumor. The authors point out that the diagnosis of astocytoma with C T is limited to grade II,that as below grade II being judged as benign while that over grade II as malignant in contrast with operation and pathology. The correic rate of C T localization is 99% and that of determining the nature 本文对100例颅内肿瘤的CT表现作了分析。认为CT诊断颅内肿瘤,除了掌握各类型颅内肿瘤CT的共性外,还必须掌握同类颅内肿瘤CT表现的不同特性。并指出,CT对星形细胞瘤的定性诊断限于Ⅱ级为界,Ⅱ级以下为良性,Ⅱ级以上为恶性。本组资科与手术结果对照,定位正确率为99%;定性正确率为79%。 Abstract cases of adrenal myelolipoma as confirmed by open surgery and pathology were reported. The commen symptons were lumbar or supper abdominal pain,abdominal mass. The main method of diagnosis were ultrasonography and CT. The characteristic of CT finding was a sharply demarcated lowdensity suprarenal mass of-120~-12 HU with round or multiseptated streaks of soft tissue of 20~30 HU. There were no obvious change on plain and constrast scans. On ultrasonography tumor was appeared as a heterogeneous... Abstract cases of adrenal myelolipoma as confirmed by open surgery and pathology were reported. The commen symptons were lumbar or supper abdominal pain,abdominal mass. The main method of diagnosis were ultrasonography and CT. The characteristic of CT finding was a sharply demarcated lowdensity suprarenal mass of-120~-12 HU with round or multiseptated streaks of soft tissue of 20~30 HU. There were no obvious change on plain and constrast scans. On ultrasonography tumor was appeared as a heterogeneous and high echosignal. Therenal arteriography was valuable to differentiate it from renal tumor. Simple excision of tumor was in treatment. 报告9例经手术、病理证实的肾上腺髓性脂肪瘤.常见的临床症状有腰或上腹部疼痛、腹部肿块。诊断主要依靠CT和B超,CT的特征是肾上腺区接近脂肪密度的类圆形肿块,边缘光滑锐利,CT值在-120~-12HU,部分为团块状、条索状的软组织密皮,CT值为20~30HU,增强扫描无明显强化。B超显示肾上腺区不均质占位,声象图上为强回声反射.动脉造影在本病与肾肿瘤相鉴别时有较大价值.治疗仅需作单纯肿瘤切除。 Common CT Diagnosis with equal ISDH is difficult,it is easy to misunderstand diagnosis,result in delaying treatment. It is help to locating qllantity quality of diagnosis,when the scan is enforced. Thepapers reported that 45 slowing is observed by operation. The characteristic of CT diagnosis show on: (1)Ventricucl system moves to the opposite,followed by ventriculi lateral cannel disappear and sick cavitas subarachnoidealis close (2)Brain cannel and commissura moves to inside (3)Middle line structure... Common CT Diagnosis with equal ISDH is difficult,it is easy to misunderstand diagnosis,result in delaying treatment. It is help to locating qllantity quality of diagnosis,when the scan is enforced. Thepapers reported that 45 slowing is observed by operation. The characteristic of CT diagnosis show on: (1)Ventricucl system moves to the opposite,followed by ventriculi lateral cannel disappear and sick cavitas subarachnoidealis close (2)Brain cannel and commissura moves to inside (3)Middle line structure moving andsick ventriculi being pressed moving and ventriculi lateralis lightly enlarging. 等密度硬膜下血肿(简称ISDH)常规CT诊断较为困难,易于漏诊、误诊向延误治疗。增强扫描有助于定位、定量及定性诊断、本文报道经手术证实的45例慢性等密度硬膜下血肿,其CT诊断特征表现有;(1)脑室系统向对侧移位,伴有侧脑沟消失和病侧蛛网膜下腔闭塞。(2)脑灰白质向内移位。(3)中线结构移位病侧脑室受压移位及对侧侧脑室的轻度扩大。
