Analysis of CT and MRI Features of Adrenal Hemangioma
Objective To investigate and summarize the imaging features of adrenal hemangioma.Methods The CT or MRI findings of 10 cases of adrenal hemangioma confirmed by surgery and pathology were retrospectively analyzed.Results Ten cases of adrenal hemangioma(6 cases on the left and 4 cases on the right)were solitary,with a maximum diameter of 29-70mm.7 patients underwent CT examination,including 1 case of CT plain scan and 6 cases of CT plain scan and enhanced.Calcification was found in 5 cases.2 cases showed low density and calcification on plain scan,but no enhancement was found on enhanced scan.1 case had hemorrhage with peripheral calcification and no enhancement.1 case had calcification in the middle and periphery with mild enhancement.The other 2 cases showed isodense and isolow mixed density on plain scan,respectively.The enhancement showed marginal nodular enhancement in the arterial phase,which spread to the central area with time delay,but the central area was never enhanced.3 patients underwent MR Examination,and the signal was heterogeneous on plain scan.1 case of low signal in the middle of FS and DWI on T2WI and high signal in the forward and reverse phase on T1WI(hemorrhage).1 case showed bright hyperintensity on T2WI FS and hypointensity on DWI and T1WI(cystic change).The enhancement pattern of these two cases was marked peripheral nodular enhancement on arterial phase and spread to the center.The other case showed scattered patchy hyperintensity in T2WI FS,DWI hypointensity,and T1WI hypointensity,with slight peripheral enhancement and delayed central enhancement.Conclusion Adrenal hemangioma has certain CT or MR Signs,and familiarity with these features can improve its diagnostic accuracy.
