Abstract

Objectives: To describe the image of brain bleeding on MRI with cavernous cerebral angiomas at Bach Mai Hospital from August 2018 to August 2019. Subjects and methods: A cross-sectional descriptive. Results: Study was performed on 45 patients, ratio of male to female was 1/1, the average age of the study subjects was 43.6. Most of the lesions were less than 30mm (96.2%). On MRI, most of the lesions, showed mixed signal on T1W pulse (55.6%), mixed signal on T2W pulse (53.3%), decreased signal on T2* (100%) and hemosiderin border around it (92.3%). After contrast injection, there was almost no enhancement (92.9%). Bleeding inside the lesion was mostly in multistage (55.8%), usually without bleeding outside the lesion (82.7%). Conclusion: Cavernous angiomas can occur in both sexes at any age. Most of the lesions were less than 30mm. The typical image on MRI is a mixed-signal on both T1 and T2-weighted images, hypointense on T2 and surrounded by a hemosiderin border. After injection of magnetic contrast, there was almost no enhancement (92.9%). Bleeding inside the lesion was mostly multi-stage (55.8%), usually without bleeding outside the lesion (82.7%).
