Abstract

Objective To study the MRI features of posterior fossasolid hemangioblastomas, in order to improve the diagnosis accurary. Methods The clinical data and MRI imaging of 15 cases with posterior fossa solid hemangiolbastomas proved were retrospectively reviewed, and summarize its characteristics. Results All of the 15cases occurred in the posterior fossa. 11 cases were solid tumors, and 4 cases were cystic-solid tumors. MRI on the solid part showed long T1 and long T2 signal, 15 cases showed the empty vessels around or in the mass with mild to moderate edema around . Enhanced scan in 11 cases of solid tumors was significantly enhanced, 4 cases of cystic- solid mass was obvious enhancement the solid part without cystic. Conclusion Certain MRI characteristics of posterior fossa solid hemangioblastomas were revealed,comprehensive analysis can improve its diagnosis accuracy.
