Imaging findings
CT reveals a funny attenuation lesion with a surrounding ring of soft tissue attenuation in the anterior mediastinum, indenting the left lung parenchyma. This was initially thought to be a fat-containing anterior mediastinal tumor.
Key takeaways
Epipericardial fat necrosis is a benign inflammatory condition that can mimic a mediastinal tumor. It typically presents as a fat-containing lesion with a surrounding rim of inflammation. While often associated with pleural effusions, it may also present without one. Biopsy is typically definitive for diagnosis.
