Purpose

To review a series of consecutive image-guided percutaneous spine and paraspinal soft tissue biopsies with radiologic-pathologic correlation and present suggestions regarding sample acquisition in order to optimize pathologic evaluation and diagnosis.

Methods & Materials

A retrospective review of consecutive image-guided percutaneous spine and paraspinal soft tissue biopsies by a single operator was performed. A total of 83 cases from 2008 to the present were reviewed. Imaging guidance consisted of fluoroscopy or CT fluoroscopy. All disc biopsies were performed with fluoroscopy and all cervical, sacral and rib biopsies were performed with CT guidance. Coaxial technique was utilized for all procedures in order to facilitate multiple lesion sampling (in order to increase specimen yield) when technically feasible and increase procedure efficiency and safety. 12-gauge trephine needles (Elson; Cook Inc.) were used for bone biopsy, 14- to 16-gauge cutting needles (Temno; Cook Inc.) were used for soft tissue cores, and 18- to 22-gauge needles were used for fine needle aspiration. All available pathology reports were reviewed for the pathologistsâ
