Abstract:
Objective To improve the recognition to synovial sarcoma in spine by discussing the imaging features of the disease.Methods The clinical and imaging data of 4 cases (2 cases of male,2 cases of female) with synovial sarcoma in spine were analyzed retrospectively, which were confirmed by surgery and pathology,the imaging features and surgical pathology were mainly analyzed.Results All the 4 patients underwent conventional CT and MRI examination,3 of which underwent CT and MRI contrast enhancement examination.On CT plain scan,2 cases showed equal density,2 showed slightly high density.After enhancement,3 cases showed inhomogeneous enhancement.On T1WI,2 cases showed low signal intensity,2 showed iso-signal intensity.On T2WI,1 case showed high signal intensity,1 showed slightly high signal intensity,and 2 showed mixed high signal intensity.On Fat suppression sequence image,2 cases showed hyperintensity,1 had mixed hyperintensity,and 1 had slightly hyperintensity.On DWI,4 cases showed obviously hyperintensity.On T1WI enhancement,1 case had significant enhancement,2 showed inhomogeneous enhancement.Conclusion The CT and MRI manifestation of synovial sarcoma in spine has certain characteristics.Combined with clinical manifestations, CT and MRI are significantly helpful to improve the cognition and diagnosis of synovial sarcoma in spine.
