Abstract

Objective To investigate the MRI findings of cerebellar hemangioblastomas. Methods The clinical data of 31 patients with cerebellar hemangioblastomas confirmed by surgery and pathology were retrospectively analyzed. All patients underwent MRI plain scan and enhanced scan. The imaging findings were analyzed. Results 23 cases of big cyst and small nodule type were quasi-circular cystic masses and the normal brain parenchyma had clear boundaries; The cyst fluid TI showed low signals while T2 showed high signals; Cyst wall TI showed equal signals while T2 high signals; There were high signal edemas around the masses in 14 cases; There were slightly higher signals on FLAIR. Enhanced scan showed that the intratumoral nodules were significantly enhanced and the cystic fluid was not enhanced. In 6 cases of solid type, 8 masses distributed in regular clumped shape and had no clear boundaries with normal brain parenchyma. There were edemas around the tumors; TI showed low signals while T2 showed high signals. There were high signals on FLAIR. Enhanced scan showed that the tumors were significantly enhanced and the cystic necrosis regions in the lesions were not enhanced. 2 cases were simple cystic type. TI showed equal signals while T2 showed low signals. There were equal signals on FLAIR. Enhanced scan showed no significant enhancement. Conclusion MRI is an important imaging method of clinical diagnosis of cerebellar hemangioblastomas and it has higher application value in qualitative diagnosis of disease.
