本文回顾了295例胶质母细胞瘤的CT表现，并与其他脑肿瘤、转移瘤和脑脓肿的CT表现进行了比较。胶质母细胞瘤的CT表现多种多样。然而，花环状CT表现，代表一个亚组的环形病变，似乎是胶质母细胞瘤最典型的表现，因为在19%的环形胶质母细胞瘤中观察到，但在172个转移瘤中仅观察到1个，在我们的系列中没有II级星形细胞瘤或脓肿病例。根据CT表现、病史及临床资料，首次CT诊断符合率为69.8%，其中复发性胶质母细胞瘤41例。在12%的病例中，胶质母细胞瘤的存在在鉴别诊断范围内。这些结果导致的结论是，在许多情况下，额外的诊断方法，如连续脑血管造影和/或脑血管造影，需要一个可靠的鉴别诊断。
The CT patterns of 295 glioblastomas examined with pre- and postcontrast scans using an EMI scanner mark I (Matrix 160/160) have been reviewed and compared with the CT appearances of other brain tumors, metastases and abscesses. There is a great variety of CT patterns with glioblastomas. However, a garland-shaped CT appearance, representing a subgroup of ring-shaped lesions, seems to be most typical for glioblastomas since it was observed in 19% of ring-shaped glioblastomas but in only one out of 172 metastases and in no case of an astrocytoma grade II or an abscess in our series. The initial CT diagnosis, based on the CT finding, the patient's history and the clinical data, was correct in 69.8% of the glioblastomas, 41 recurrent glioblastomas included. In 12% of the cases the presence of a glioblastoma was within differential diagnosis. These results lead to the conclusion that in many cases additional diagnostic methods, such as serial scintigraphy and/or cerebral angiography, are required for a reliable differential diagnosis.
