Ultrasonically guided percutaneous biopsy of peripheral pulmonary masses.
Ultrasonically guided percutaneous biopsy and aspiration of solid and cystic structures in the abdomen, neck, and pericardial space are common practice. The technique may be utilized for biopsy of peripheral pulmonary masses in contact with the chest wall, in order to assure accurate placement of the needle in the center of the mass, reduce the risk of pneumothorax, and eliminate the exposure to radiation that occurs with fluoroscopic guidance. Four patients had successful biopsies in this manner, without complications. Histologic studies revelaed malignant neoplasms in three and lipoid pneumonia in one.
