Thoracic myelolipomas are extremely rare entities; only ~3% of myelolipomas are thought to occur in the thorax. When do occur in the thorax they can manifest as
- mediastinal myelolipoma: most occur in the posterior mediastinum
- intrapulmonary myelolipoma (much less common)
As with myelolipomas in general they considered a benign tumor composed of mature adipose tissue and normal hematopoietic cells 2.
Features can be variable dependent on location. CT may be able to identify fat components within the lesion. They generally tend to be small lesions (<5 cm 1). Pulmonary myelolipomas are mostly seen as small nodules,
