Radiological Study of Skeletal Desmoplastic Fibromas(A Report of 6 Cases) / 实用放射学杂志

ABSTRACT

Objective To explore the clinical and radiological findings of skeletal desmoplastic fibromas.Methods Radiographs of six patients with desmoplastic fibromas proved by pathology were retrospectively reviewed.Results Two tumors arose in femur,two in tibia,one in radius and one in humur.In plain radiography,these lesions were always metaphyseal and expansile lytic with a reactive bony rim(n=6).They often had a trabeculated or honeycomb appearance into lesion and four tumors invaded adjacent soft tissue.Conclusion Desmoplastic fibromas of long bones are nearly always metaphyseal.Radiographs disclose a expansile lytic lesion with a sclerotic rim and a trabeculated apperance into it.And the "root hair"sign is fairly characteristic for this tumor.No calcification and periosteal reaction can be seen.
