Lumbosacral Paraspinal Intramuscular Myxoma: Case Report and a Brief Literature Review

Myxoma is a tumor of mesenchymal origin with a slow-growing behavior and an unknown etiology, occurring in a variety of locations. It mostly affects the heart's chambers, but large skeletal muscles may also harbor these neoplasms (i.e., intramuscular myxoma [IM]) at a lower frequency. Lumbosacr...

Description
Summary:Myxoma is a tumor of mesenchymal origin with a slow-growing behavior and an unknown etiology, occurring in a variety of locations. It mostly affects the heart's chambers, but large skeletal muscles may also harbor these neoplasms (i.e., intramuscular myxoma [IM]) at a lower frequency. Lumbosacral paraspinal IM is very rare, and only five cases have been reported worldwide, with none in the Brazilian population. We present the first Brazilian case: a 38-year-old woman complaining of increased volume and pain in the right lumbosacral region in the last two months without radiculopathy and without focal neurological deficits. Imaging showed a large paraspinal lumbosacral tumor from the second lumbar vertebra to the second sacral segment. This was completely removed by a posterior approach. Histopathological revealed an intramuscular myxoma. Surveillance imaging for four months after surgery revealed no recurrence and the patient was doing well. Literature on the topic was reviewed.
