Imaging manifestations and pathologic features of splenic lymphangioma / 中华普通外科杂志

ABSTRACT

Objective To explore CT,MRI and 18F-FDG PET/CT features of splenic lymphangioma.Methods A retrospective analysis of 18 pathology proved splenic lymphangioma cases was made,including their clinical,imaging characteristics and pathological findings.15 cases with plain and enhanced CT scan,6 cases with plain and enhanced MRI scan and 1 case with 18F-FDG PET/CT examination.Results (1) 13 cases were single lesion,4 cases were multiple lesions and 1 case was lymphangiomatosis.The largest diameter was 15.8 cm,minimum diameter was less than 1.0 cm.(2) On CT imaging:cystic watery density and equal density interval was showed in 12 cases,in 3 cases as solid and slightly were showed lower density.Calcification was showed in 3 cases.On enhanced CT,internal septa was slightly enhanced and progressive inhomogeneous enhancement was shown in 3 cases.(3) On MRI imaging:cystic content was manifested as low signal on T1WI and high or highlight signal on T2WI,and there was a difference between the lesion and the splenic tissue on DWI.(4) One case underwent PET/CT imaging:18F-FDG uptake was not increased.Conclusions Preoperative CT,MRI and 18F-FDG PET/CT help establish a tentative diagnosis of splenic lymphangioma while final diagnosis relies on pathological examination.
