Clinical,imaging and pathological analysis of children with myofibroma
Objective To investigate the clinical,imaging,and pathological manifestations of myofibroma in children.Methods The data of 31 patients with myofibroma confirmed by pathology were analyzed retrospectively,and the imaging features were observed.Results Among the 31 cases,28 cases were treated with subcutaneous painless mass.There were 28 cases of single lesions and 3 cases of multiple lesions.There were 5 cases with calcification,13 cases with cystic degeneration,and 12 cases with capsules.The enhanced scan showed mild to moderate progressive enhancement in 8 cases,obvious uniform/uneven enhancement in 11 cases(obvious peripheral enhancement in 5 cases),and no obvious enhancement in 2 cases.Among them,26 cases were subcutaneous type,mainly manifested as subcutane-ous round mass,with uniform or uneven density/signal,and the enhancement was mainly mild to moderate progressive enhancement or obvious enhancement.There were 3 cases of intraosseous type,mainly manifested as expansive bone destruction,without periosteal reaction and sclerotic edge,with uniform density/signal and obvious enhancement.There were 2 cases of visceral type,mainly with obvious uneven mass enhancement.Conclusion The imaging findings of myofibroma are characteristic,especially the subcutaneous and intraosseous types,which are highly consistent with pathology.Preoperative imaging examination can clearly show the size,number,enhancement and visceral involvement of the lesions.
