Presacral myelolipomas can occur in patients with a medical history of malignancy, steroid use, and\/or endocrine disorders including diabetes mellitus. A 65-year-old man with no specific medical history experienced temporal abdominal pain without bowel symptoms that lasted a few hours. By the time he visited a hospital, the pain had diminished. Computed tomography failed to detect any abnormality in the abdominal or pelvic organs that would have caused the abdominal pain but revealed a lesion 4\u2009cm in diameter in the frontal sacrum. Magnetic resonance imaging showed that the lesion contained fat elements with a high signal intensity on T1- and T2-weighted images, which was decreased on fat-suppression T2-weighted images. Computed tomography\u2013guided biopsy and imaging allowed a diagnosis of presacral myelolipoma. After 3\u2009months, hematochezia was observed, and follow-up examination revealed rectal carcinoma with multiple lung metastases. He died due to spread of the cancer despite chemotherapy, 6\u2009months after the cancer was found. Considering the possible association between presacral myelolipoma and cancer, presacral myelolipoma might be a cancer parasymptom. Checking for possible malignancy may therefore be warranted in patients with presacral myelolipoma, especially in those without diabetes mellitus.<\/jats:p>","DOI":"10.1177\/2036361318772124","type":"journal-article","created":{"date-parts":[[2018,4,23]],"date-time":"2018-04-23T03:24:45Z","timestamp":1524453885000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Presacral
