Elastofibroma dorsi: an under-diagnosed entity -clinical, imaging and pathological features

ABSTRACT

To report clinical, radiological and histopathological findings of elastofibroma dorsi.Thepurposeis to increase awareness among radiologists and clinicians of this under-diagnosed and interesting benign lesion. Retrospective review of 624 consecutive thoracic Computed Tomography [CT], 92 ultrasounds and 130 Magnetic Resonance Image [MRI] scans for detection of elastofibroma dorsi along with review of the clinical and histopathological findings. Three radiologists evaluated the imaging features using previously definedcriteria. A histopathologist reviewed the pathological findings. A tertiary level hospital and a specialized orthopedic center. Patients who were subjected to CT, Ultrasound and MRI scans of the thorax Interventions: CT, MRI, Ultrasound scans of the thorax and surgical excision. Detection of elastofibromasand their clinical, radiological and histopathologic findings. Only 50% of patients with elastofibrom a dorsicouldbe detected by all modalities though, on review, all lesions showed characteristic location, morphology, imaging as well as typical clinical and pathological features. Significant contrast enhancement of all lesions on MRI was an unusual finding in our study. An awareness of the radiological findingsand enhancement patterns on CT and MRI can help in the proper diagnosis of elastofibroma dorsi an entity often misdiagnosed in a high percentage of patients
