摘要

Astrocytomas are tumors that arise from astrocytes—star-shaped cells that make up the “glue-like” or supportive tissue of the brain. Astrocytomas can appear in various parts of the brain and nervous system, including the cerebellum, the cerebrum, the central areas of the brain, the brainstem and the spinal cord. The main objective of this study was to detect the sensitivity of the CT scan in diagnosis of the brain astrocytoma, in patients who were confirmed as brain gliomas using computerized tomography of the brain versus brain tissue biopsy after surgery. One hundred and one patients were included in this study. Bio-data collected for these patients (age, gender), radiographic appearance, contrast enhancement and the site of the tumor, were statistically analyzed. Out of the 101 patients with brain gliomas, 52 (51.5%) were male whose ages ranged between 1 and 80 years, and 64 (63.4%) cases were diagnosed as astrocytoma by CT. This study concluded that the CT brain was sensitive in the diagnosis of brain astrocytomas.
