RESUMO
PURPOSE:
To report the experience of a radiology department in the use of computed tomography - guided cutting needle biopsy of pulmonary nodules, by evaluating diagnostic yield and incidence of complications.METHODS:
This is a retrospective analysis of 52 consecutive patients who underwent lung lesion biopsy guided by computed tomography, performed between May 1997 and May 2000. Thirty-five patients were male and 17 were female, with ages ranging from 5 to 85 years (median, 62 years). The size of the lesions ranged from 1.8 to 15 cm (median, 5.4 cm).RESULTS:
In a total of 52 biopsies of lung lesions, 51 biopsies (98.1 percent) supplied appropriate material for histopathological diagnosis, with 9 diagnosed (17.3 percent) as benign and 42 (80.8 percent) as malignant lesions. Specific diagnosis was obtained in 44 (84.6 percent) biopsies 4 benign (9.1 percent) and 40 (90.9 percent) malignant lesions. The sensitivity, specificity, and accuracy of the cutting needle biopsies for determining presence of malignancy were 96.8 percent, 100 percent, and 97.2 percent, respectively. Complications occurred in 9 cases (17.3 percent), including 6 cases (11.5 percent) of small pneumothorax, 1 (1.9 percent) of hemoptysis, 1 (1.9 percent) of pulmonary hematoma, and 1 (1.9 percent) of thoracic wall hematoma. All had spontaneous resolution. There were no complications requiring subsequent intervention.CONCLUSION:
The high sensitivity and specificity of the method and the low rate of complications have established cutting needle biopsy as an efficient and safe tool for the diagnosis of lung lesions. In our hospital, cutting needle biopsy is considered a reliable procedure for the evaluation of indeterminate pulmonary nodules
