Background: Elastofibroma dorsi is a rare benign soft-tissue pseudotumor typically located in the infrascapular region, often discovered incidentally or during evaluation of a slow-growing mass. Case Presentation: We report the case of a 53-year-old woman who presented with a gradually enlarging, painless right infrascapular swelling of two years’ duration. Clinical examination revealed a soft, ill-defined mass. Magnetic resonance imaging (MRI) demonstrated bilateral infrascapular poorly circumscribed lesions, isointense to skeletal muscle, with alternating linear hyperintense and hypointense streaks, consistent with elastofibroma dorsi, no Diffusion restriction or enhancement after gadolinium injection. Conclusion: MRI findings are often pathognomonic, allowing diagnosis without biopsy. Recognizing this entity is important to avoid unnecessary invasive procedures.
