Imaging Diagnosis of Nuchal-type Fibroma

Abstract

Objective: To study the CT and MRI findings of nuchal-type fibromas. Methods: Eight cases of surgically resected and pathologically confirmed nuchal-type fibroma were retrospectively analyzed. Results: All lesions were firm and located in the subcutaneous tissue of the sacrococcygeal region. Upon CT and MRI, local skin thickening was observed . The lesions were ill-defined and had irregular morphology. Moreover, the lesions showed slightly high density on CT, low signal intensity on T1WI and T2WI, and isosignal on DWI. Enhancement scanning was performed in two patients, with one mild and one moderate enhancement. Conclusion: The CT and MRI findings of nuchal-type fibromas have some characteristic features. Combined with medical history and clinical manifestations, these can assist in diagnosis
