Role of Percutaneous Needle Biopsy Guided by Chest Sonography in Diagnosis of Peripheral Chest Lesions
Ayman Ahmed Fouad Mahmoud;
Abstract
One hundred patients, with peripheral thoracic lesions, were included in this study (70 males and 30 females) during the period between August, 1999 and August,
2000. These patients were admitted to chest department of Assuit University Hospital and submitted to complete history, clinical examination, X-ray chest P-A and lateral views, CT chest scanning, chest US, and other routine investigations. US-guided needle biopsy was performed among 50 patients, and its diagnostic accuracy was compared with that of CT guided needle biopsy in another 50 patients matched with the sonographic group as regards age, sex, and type of radiological abnormalities.
Ultrasound (US)-guided transthoracic biopsy is well suited for the sampling of those pleural, pulmonary, chest wall, and mediastinal lesions that provide an adequate acoustic window to the transducer. The chest wall, pleural and peripheral lung lesions are generally hypoechoic relative to their surrounding tissues. A special puncture /
transducer was used to perform US-guided biopsy with real-time visualization of the . .
biopsy needle and the lesion.
The sensitivity of chest US Ill evaluation of pleural, peripheral pulmonary, anterior mediastinal and chest wall lesions was 95%, 96.9%, 71.4% and 100% respectively while the specificity of US was 100% each. US only missed the air in the pleura in 2 cases of hydro-pneumothorax (out of 40 pleural lesions), while it did not demonstrated central pulmonary tumors associated with pleural effusion (out of 65 pulmonary lesions) and 2 cases of mediastinal lymphadenopathy associated with pleural effusion (out of 7 mediastinal lesions). No cases of chest wall lesions were missed by chest US.
The diagnostic yield of US-guided needle biopsy was 80%, 94%, 60% and
100% for pleural, pulmonary, mediastinal and chest wall lesions respectively. The overall diagnostic success of US- guided needle biopsy of different peripheral thoracic lesions was 88%. No complications were recorded among US-guided biopsy group while either pneumothorax or haemoptysis was reported in 2% of CT-guided needle biopsy. The peripheral nature of lesions accessed by US guidance accounts for the absence of complications.
