Sacral myeloid sarcoma involving multiple metastases to the brain: A case report.

The presentation of myeloid sarcoma (MS) in the bone is common; however, rarely does the tumor occur in the sacral spine, and in a normal patient with no history of acute myeloid leukemia. The present study describes the rare case of a previously healthy 24-year-old male patient, who presented with a history of six months of repeated pain in the right leg and hip and limping for less than a month, who was diagnosed with sacral MS. Despite receiving surgical management and chemotherapy promptly subsequent to the diagnosis and undergoing close observation following the treatment, the patient still developed metastases to multiple sites of the brain. Taking into account the similar presentation of this rare disease to other entities, the early and accurate diagnosis of MS is vital, and the condition should be considered as a threatening manifestation with the possibility of metastasis to other sites of the body.
