小儿颅内肿瘤的CT诊断和鉴别诊断(附156例分析)

Diagnosis and Differential Diagnosis by CT Scan of Intracranial Tumors in Children(Analysis of 156 Cases)

分析156例15岁以下小儿颅内肿瘤,包括星形细胞瘤73例、颅咽管瘤25例、髓母细胞瘤23例、室管膜瘤13例、松果体瘤8例、脑膜瘤、垂体瘤、结核瘤各2例,其它肿瘤8例。幕上85例,幕下71例。小儿颅内肿瘤以星形细胞瘤多见。幕上以颅咽管瘤、松果体瘤最为常见;幕下以髓母细胞瘤、室管膜瘤为常见。CT对颅内肿瘤有较高的诊断价值,可以准确定位,为手术提供可靠的依据。同时通过病变部位、密度高低、病灶的大小、形态及与周围的关系可以推测病理诊断。此外,CT可以用于发现颅脑术后并发症。

CT scanning of 156 pediatrie cases (<15y) with mtracranial tumors was analyzed. All of the tumors included astrocytoma(73 cases) ,craniopharyngioma(25) ,medulloblastoma(23) ,ependymo-rna(13), pmealoma (8), meningiorna (2) ,pituitary adenoma (2) , mtracranial tuberculoma (2) , and other tumors (8); 85 tumors were in the supratentorium, 71 m the infratentorium- The most com-mon intracranial tumors in children were astrocytoma. Most of the craniopharyngioma and pinealo-ma were in the supratentorium. Most of the rnedulloblastoma and ependymoma were in the in-fidtentonum. CT scans could show the accurate location of intracranial tumors and therefore direct operations, The location.density,size and shape.s of li-sions of CT scan might offer the esliniation of pathologic.al changes of the tumors. CT scans could ..how intracranial complications after the operations.
