Abstract Paraspinal intramuscular myxomas (IMMs) are exceedingly uncommon and may cause neurological symptoms due to mass effect on the spinal cord, although most present as large, painless masses. In this case, the patient is a 57-year-old female who presented with an incidental finding of a right paraspinal mass at the L4 level on routine magnetic resonance imaging (MRI). Using intraoperative navigation, an incision was made along the paraspinal muscles, and the tumor was removed with margins. The patient stayed for overnight observation and was then discharged the following morning with no complications and proper pain management. At 1-year follow-up, she was clinically doing well with no radiographic evidence of recurrence. This report demonstrates the 9th documented case of an IMM in the lumbosacral paraspinal musculature. IMMs are distinct from other myxoid tumors in that they have no recurrence rate if the tumor is resected in its entirety with appropriate margins; therefore, it is essential to consider this pathology prior to surgical planning to ensure maximal resection.
