Abstract

Many different abnormalities, such as, neoplasm, infection, traumatic hematoma, or congenital or immune myopathy, may be found in the paravertebral muscles. However, neoplasms of paravertebral muscle are an uncommon cause of back pain. Such neoplasms may arise from local lesions or due to metastatic spread from a distant malignancy. The differential diagnoses of a primary soft tissue malignancy and metastatic spread from a skeletal muscle tumor are important. In cases of soft tissue sarcoma, histopathological findings and surgical margins are both related to local recurrence and metastasis, therefore, percutaneous needle biopsy may be helpful before surgical excision. A degree of surgical excision is decided based on considerations of muscular function and histopathological findings.
