[Abstract]ObjectiveTo investigate the valueof magnetic resonance imaging（MRI）inthe diagnosis ofsoft tissue hemato masof thextremities.MethodsAretrospectiveanalysis wasperformedforthe MRImanifestationsandclinicaldataof14patientswith softtissue hematomasoftheextremities，andaliteraturereview wasalsoperformed.ResultsAmong thel4patients，there were 9 male patients and 5 female patients，with an age of 11-80 years.As for the location and distribution of le sions，there werel patients with intramuscular hematomaand 3 patients with subcutaneous hematoma，and there were 1l patientswithhematomainthelowerextremitiesand3patientswithhematomaintheupperextremities.Asforthemorphologyand sizeoflesions，therewere4patientswithspindleshapedlesions，6withoval-shapedlesions，and4withiregularshapesoflesions， and the hematomas showed the largest diameter of 14.4cm and the smallest diameter of 1.0cm ，with a mean diameter of 6.1cm Compared with the skeletal muscle，the main signal components of the 15 lesions in14 patients were short T1 and long T2 signals in 6 patients，mixed T1 and mixed T2 signals in 4 patients，isotropic T1 and long T2 signals in 1 patient，long T1 and short T2 signals in 1 patient，and long T1 and long T2 signals in 2 patients. Contrast-enhanced scan showed ring enhancement and marginal enhancement in 7 patients. Type I time-signal intensity curve（TIC） was observed inside the hematoma，while type I TIC was observedforthewallof thehematomas.ConclusionTherearediverseandcomplexMRIsignalsforsoft tisuehematomasofthe extremities，ndTCofdynamiccontrastenancedmagneticresonanceisof greatsignificanceinthediagnosisofsofttisuematomas of the extremities.
