The danger of percutaneous needle biopsy of the lung has been emphasized by the recent report of two additional fatal cases.' The authors review the published fatalities in the English literature, pointing out that they have occurred, except in one case,2 after the use of cutting needles.

Departamento de Cirurgia Torácica, Hospital Israelita Albert Einstein, Albert Einstein, São Paulo (SP) Brasil. A 56-year-old male patient underwent percutaneous biopsy of a nodule in the right lung apex (Figure 1A). The tip of a 19-gauge coaxial needle was positioned in the posterior ch...

The purpose of this study is to evaluate the risk factors for the severity of pneumothorax after computed tomography (CT)-guided percutaneous lung biopsy using the single-needle method. We reviewed 91 biopsy procedures for 90 intrapulmonary lesions in 89 patients. Patient factors were age, sex, history of ipsilateral lung surgery and grade of emphysema. Lesion factors were size, location and pl...

The merits of computed tomography (CT) guided percutaneous needle biopsy of lesions throughout the body have been well documented in the recent literature (1-4). Radiologists have employed this technique for sampling lesions involving the vertebral body and adjacent softtissues (5-7). This report describes a coaxial needle system (CoANS) which has several advantages over the tandem needle techn...

BACKGROUND AND OBJECTIVE With the development and refinement of guidance modalities for percutaneous biopsies, many investigators have reported studies supporting the role of guided core needle biopsy in the diagnosis of mediastinal lymphoma. The aims of this report are to evaluate the efficacy of findings at core needle biopsy of mediastinal masses on patient care and define the key determinan...
