Purpose : To evaluate the diagnostic value of CT-guided percutaneous biopsy of inflammatory and tumorous lesions of the spine and paraspinal soft tissue. Materials and Methods : Twenty-three patients underwent CT-guided percutaneous biopsy of the spine and paraspinal soft tissue. Tentative clinical diagnoses determined before biopsy were tuberculous spondylitis (n=5), pyogenic spondylitis (n=4), butterfly vertebra (n=1), old compression fracture (n=3), discitis (n=1), hemangioma (n=1), metastasis (n=7) and multiple myeloma (n=1). Biopsy was performed at the following levels: cervical-(n=1), thoracic-(n=9), and lumbar-spine(n=13). The approach to biopsy of the spine and paraspinal soft tissue lesions was posterolateral (n=11), posterior (n=2), or transpedicular (n=10). Results : Tissue considered adequate by the pathologist involved was obtained in 21 (91%) of the 23 cases. In 19 cases, pathologic findings supported the clinical diagnoses determined before biopsy. In two cases, patho-logic and clinical diagnoses differed. Complications such as severe pain, bleeding, infection, neurologic deficit or damage to internal organs were detected neither during or after the procedure. Conclusion : CT-guided percutaneous biopsy is a safe and reliable method of obtaining a diagnosis in many cases involving different spinal and paraspinal lesions. |
