Myelolipomas are uncommon benign tumors composed of mature adipose tissue mixed with hematopoietic elements; these tumors can occur in both the adrenal glands and extra-adrenal locations, the presacral region being the most frequent extra-adrenal site. We present a case of presacral myelolipoma diagnosed by fine needle aspiration (FNA) and core needle biopsy (CNB) in a 55-year-old woman with concurrent invasive ductal breast cancer. TC and RM imaging were consistent with the diagnosis of presacral myelolipoma. The lesion was discovered incidentally during the staging procedure for breast malignancy. The purpose of our work is to describe the FNA and CNB finding in combination with the imaging features of this uncommon lesion.
