Abstract：Objective The imaging findings and pathological features of the solid hemangioblastoma ( SHB) in childhood were analyzed.Methods CT and MRI findings of eight patients (6 cases of male, 2 cases of female, age range 5~14 years old, mean 9.5 years old) with SHB proved by pathology were analyzed retrospectively.CT plain scan was performed in 7 cases, CT enhancement scan were performed in 6 cases, MRI plain and enhancement scan was performed in 8 cases.Results All patients of SHB located in the posterior fossa (3 cases in the left cerebellar hemisphere, 2 cases in the right cerebellar hemisphere, 3 ca-ses in the region of fourth ventricle) .In 6 patients, the tumor presented as a solitary, oval or rounded and well-defined mass with clear boundary, and in other 2 patients, the tumor was manifested as an irregular mass with lobulated margin.Plain CT showed iso-density and low-density, and plain MRI showed that on T1 WI the lesions was characterized by iso-intensity or slightly low-in-tensity signals and on T2 WI the lesions exhibited heterogeneous iso-intensity and hyper-intensity signals; the space-occupying effect was obvious with edema; multiple abnormal vessels were observed in tumor and peritumor; MRI enhancement scanning showed the solid tumors were significantly enhanced.Conclusion The incidence of the solid hemangioblastoma in childhood is very low, but CT and MRI performance is of characteristics.CT and MRI examination facilitates the tumor positioning and qualita-tive diagnosis.
