Abstract
A 71-year-old female presented with chronic shortness of breath and underwent routine examination at the emergency department. A plain chest radiograph revealed a large lobulated posterior mediastinal mass that was incidentally found to be unrelated to the main complaint. Further cross-sectional images were obtained to characterize the lesion, which revealed bilateral involvement of a prevertebral mixed attenuation large mass with minimal enhancement postcontrast administration. Images were not conclusive in which the patient underwent ultrasound-guided biopsy and further histopathological examination, which revealed a myelolipoma of the posterior mediastinum, a rare entity to be seen at that location. Here, we present the case of posterior mediastinal myelolipoma.
