Background and Aim: Intramuscular myxomas are uncommon benign tumors that are rarely seen in the paraspinal musculature. They might present with neurological symptoms if situated near the spinal cord or may present with nonspecific symptoms such as back pain.
Case Presentation: The case of this study was a 46-year-old female presented with back pain that was exacerbated with movement. A thoracolumbar magnetic resonance imaging revealed a T2 hyperintense 35x25x85 mm mass that extends craniocaudally within the right-sided paraspinal muscles with heterogeneous contrast enhancement on T1 sequence images. Using a paramedian incision, paraspinal muscles were dissected, and a rubbery mass was palpated within. The tumor was mobilized in all quadrants and removed with its pseudocapsule. The tumor internally had a gel-like substance with rubbery margins. The patient was discharged without complications.
Conclusion: To our knowledge, this is the 16th case of paraspinal intramuscular myxoma in the literature. Even though it is a rare entity, one must be vigilant for pathologies within the paraspinal muscles in patients with back pain
