ROSALES OLIVAREZ, Luis Miguel et al. Evaluation of transpedicular percutaneous biopsy guided by CT. Coluna/Columna [online]. 2012, vol.11, n.3, pp.209-213. ISSN 1808-1851.

OBJECTIVE: To evaluate the usefulness of percutaneous transpedicular biopsy guided by CT together with systematic studies such as diagnostic tests of the etiology of vertebral destruction. METHODS: Case series, prospective and crossover study of 21 patients who underwent percutaneous transpedicular biopsy guided by CT and laboratory tests and radiological studies from March to July 2011, to evaluate its usefulness in the diagnosis of vertebral destruction. RESULTS: We analyzed 21 patients, 14 men and 7 women, mean age 59.2 years, whose most affected levels were L1, L2, and L3. The biopsy report had diagnostic accuracy of 90.4%. In 2 patients the clinical correlation between biopsy and systematization of diagnostic studies was carried out. CONCLUSION: CT-guided biopsy is a simple, useful, inexpensive, and effective technique for the study of vertebral destruction; the systematic studies allow us to corroborate the diagnosis made by biopsy.
