CT and MRI Diagnosis of Orbital Muscle Cone Hemangiopericytoma

Objective: To investigate the orbital muscle cone hemangiopericytoma(HPC) CT and MRI manifestations and pathologic characteristics, in order to improve the understanding of HPC. Methods: The literatures review, review findings, pathologic characteristics, treatment and prognosis of HPC images in 1 case proved by operation and pathology. Results: HPC CT showed soft tissue density, MRI performance with the T₁ signal, T₂ signal, see feature multiple small flow void signal, intraocular muscle and optic nerve were compressed, existence, fat gap ball after enhanced scanning lesions showed homogeneous enhancement. Conclusion: In depth understanding of CT and MRI manifestations and pathologic features of HPC, it has significant value in diagnosis, treatment and prognosis of HPC.
