Abstract

Objective: To investigate the characteristics of tumor magnetic resonance imaging in glioblastoma patients at National Cancer Central Hospital. Subjects and methods: Cross-sectional tissue study on 34 glioblastoma patients who underwent surgery, magnetic resonance imaging and combined chemotherapy and radiotherapy at K Central Hospital, Tan Trieu campus from 01 2019 to December 2020. Results: Most of the tumors were in one hemisphere, usually appearing in frontal lobes (26.5%), temporal (17.6%), mixed (41.2%). The average tumor diameter is 5.0 ± 1.6 cm, mainly tumors with unclear boundary (55.9%), heterogeneous signal (94.1%), mixed tumor (94.1%). Other features associated with the tumor such as cerebral edema accounted for 82.4%; ventricular compression accounted for 67.6%; Calcification accounted for 2.9%; necrosis - hemorrhage accounted for 55.9%; More than 97% of tumors captured contrast after injection. More than 60% of patients have midline deviation due to tumors. Conclusion: Glioblastoma is usually large, compresses the midline, is located on one side of the brain, is common in the frontal and temporal lobes, and often has unclear tumor boundaries, mixed structure, usually intratumoral necrosis or peritumoral cerebral edema.
