[The isolated pulmonary nodule. Biopsy guided by x-ray computed tomography].
Transparietal CT-guided biopsy location can be successfully performed for isolate pulmonary nodules, defined as lesions with a maximal diameter of 3 cm, without any other parenchymal or mediastinal abnormality. A 21 G needle has been used according to an identical protocole in 64 cases (10 benign, 54 malignant). The biopsy was successful in 77.7% of the malignant cases. In relation to the diameter of the nodules, biopsy was successful in 66.7% of the nodules smaller than 2 cm and in 76% of the nodules ranging from 2 to 3 cm. The complications observed were rare (1 case of pneumothorax requiring drainage, 9 cases of pneumothorax without clinical signs and simply followed up, 4 cases of minor hemoptysis requiring no treatment and 5 cases of hematomas smaller than 5 cm on CT).
