BACKGROUND: Elastofibroma dorsi (ED) is a benign soft tissue tumor that classically presents as an ill-defined mass at the inferior pole of the scapula. Several studies have indicated the benefits of using magnetic resonance imaging (MRI) to identify ED. In this study, we calculate the sensitivity and positive predictive value (PPV) of MRI in the diagnosis of ED using histopathology as the gold standard diagnostic method. Clinical characteristics of ED and radiologic features of MRI as well as treatment options are discussed. MATERIALS AND METHODS: A systematic retrospective review was performed of all ED patients treated in our center between 1999 and 2009. MRI and histopathology samples were performed in all cases. The MRI sensitivity and PPV in the diagnosis of ED were calculated. RESULTS: A total of 15 patients who were treated within the study period were reviewed; of these, were 14 (3 men, 11 women) true ED cases. MRI scan results matched the histopathology in 14 of 15 patients; 1 false-positive patient was observed, and no false-negative patients (negative MRI and positive histopathology) were noted. The PPV and sensitivity of MRI scan in the diagnosis of ED were 93.3% (95% confidence interval, 68.0%-100.0%) and 100% (95% confidence interval, 75.2%-100.0%) respectively. CONCLUSIONS: MRI is a useful tool for assessment of ED and can potentially help avoid the need for unnecessary biopsy and surgery, especially in the asymptomatic patient.
