Abstract:
Objective To discuss CT,MRI features of fibrous hamartoma of infancy (FHI) compared with pathology.Methyls Cinical data,CT and MRI findings,as well as pathological results of 15 patients with FHI were retrospectively analyzed.Results Totally,there were 17 lesions of FHI in 15 cases,including 13 cases with single lesion and 2 cases with double lesions.The lesions manifesting as subcutaneous-,skin-and mixed-type on CT or MR images accounted for 58.82％ (10/17),17.65％ (3/17) and 23.53％ (4/17),respectively.The subcutaneous-and mixed-type lesions showed " cloud sign" (including "thin-cloud sign" and "thick-cloud sign").The thin-cloud sign lesions composed mainly of mature adipose tissue,while the triphasic composition ratio of adipose,fibrous and primitive mesenchymal cells were relatively consistent in the lesions with thick-cloud sign.The skin-type lesions showed "mountain-inverted sign",which composed mainly of immature mesenchymal component.Conclusion CT and MRI features of FHI are complex,yet have certain characteristics,which can preferably reflect the histopathological features of FHI.
