Ultrasound guided percutaneous biopsies of suspected mediastinal lesions.

چکیده
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.

Percutaneous needle biopsy of the mediastinum: review of 94 procedures.
BACKGROUND A number of reports of radiologically guided percutaneous biopsy of mediastinal masses have been described but techniques have varied, particularly the type of needle used. In this study mediastinal biopsies with fine aspiration needles and cutting needles have been compared, sometimes in the same patient. The results are reviewed with particular emphasis on the choice of biopsy need...

Biopsies of thoracic lesions guidance. 22 of the 1 12 lesions were mediastinal and 83 were pleuroparenchymal. A large-bore 14-gauge Tru-cut needle was used in all patients. Adequate specimens for histologic examination were obtained in 98%. The overall accuracy was 91 % with 9% false negative and no false positive diagnoses. Despite the large size of the needle, the total number of complic...

BACKGROUND Lesions detected by positron emission tomography-computed tomography (PET-CT) during the analysis of thoracic tumours are often impalpable at physical examination, and subsequent ultrasound (US) may aid in finding these lesions for pathologic evaluation. OBJECTIVES The success rate of percutaneous US-guided biopsies of palpable and non-palpable lesions and the impact on tumour stag...

PURPOSE We aimed to explore the value of contrast-enhanced ultrasonography (CEUS) in guidance of percutaneous biopsy of anterior mediastinal lesions. METHODS Ninety patients with solitary anterior mediastinal lesions (55 males, 35 females; mean age, 46±4 years) were included. Patients were randomly divided into CEUS group (n=45) and conventional ultrasonography (US) group (n=45). Real-time US...
