Abstract
Realtime ultrasonography with general purpose sector transducer was used to guide 87 percutaneous biopsies on 82 patients with lesions suspected to be mediastinal masses on plain chest radiographs. In seven patients who had dyspnea the biopsies were done in erect or semi-erect sitting positions. Definitive diagnosis was obtained from 66 lesions (80.5%) where 46 (70.0%) were mediastinal and the remaining 20 lesions (30.0%) arising from the lung. Of the 46 mediastinal lesions where specific diagnosis were made, 42 (91.0%) were anterior and four (0.9%) posterior mediastinal lesions. The majority of these anterior mediastinal masses were lymphomatous nodes followed by germ cell tumours whereas all four posterior mediastinal masses were neurogenic. Of the lung lesions, 19 were primary malignancies. The remaining lung lesion which was located posteriorly was cryptococcus infection. One patient developed massive hemothorax, but subsequently recovered. No significant complications were encountered in the remaining patients. Surgery was carried on 11 patients. There is correlation between definitive diagnosis from percutaneous biopsy and final diagnosis after surgery in 80 % of patients. It is proposed that all percutaneous biopsies for thoracic masses which abut the chest wall and cause mediastinal widening on a plain chest radiograph be guided by ultrasound. It can be effectively accomplished with ease and safety even without the use of dedicated biopsy ultrasound probes or biopsy attachments, and on patients in erect or semi-erect positions. Key words: Mediastinal masses, ultrasound, percutaneous biopsy.
