BackgroundLung auscultation and bedside chest radiography are routinely used to assess the respiratory condition of ventilated patients with acute respiratory distress syndrome (ARDS). Clinical experience suggests that the diagnostic accuracy of these procedures is poor.MethodsThis prospective study

Comparative Diagnostic Performances of Auscultation, Chest Radiography, and Lung Ultrasonography in Acute Respiratory Distress Syndrome

Lung ultrasound can be routinely performed at the bedside by intensive care unit physicians and may provide accurate information on lung status with diagnostic and therapeutic relevance. This article reviews the performance of bedside lung ultrasound for diagnosing pleural effusion, pneumothorax, alveolar-interstitial syndrome, lung consolidation, pulmonary abscess and lung recruitment/derecruitment in critically ill patients with acute lung injury.

Clinical review: Bedside lung ultrasound in critical care practice

Role of thoracic ultrasound in the assessment of pleural and pulmonary diseases

Fine-needle aspiration (FNA) biopsy findings are presented in three cases of localized fibrous tumor of pleura (LFTP). Clinically, two of the tumors behaved benignly, although one showed frequent mitoses and foci of necrosis. The third tumor exhibited local aggressiveness as evidenced by rib destruction. Cytologically, these tumors exhibited a wide range of cellularity, composed mainly of small, bland oval to spindle cells with moderate numbers of stripped nuclei. Small bits of collagen were seen in the smears. In all cases, cell blocks were instrumental in making the diagnosis. Previous cytologic descriptions of the tumor are briefly reviewed and the cytologic differential diagnosis is discussed. The peripheral location of this uncommon tumor makes it an ideal target for FNA biopsy.

The value of sonography in lung diseases such as sarcoidosis is not established. Twelve patients with pulmonary sarcoidosis and eight control subjects underwent a sonographic examination using a high frequency probe (7.5 MHz). The normal lung surface showed smooth and regular hyperechoic patterns, respiratory motions, and occasionally minute interruptions with comet tails. All patients with sarcoidosis showed various surface abnormalities, which appeared irregular and rough with coarse interruptions, producing an increase of artifacts. Nodular patterns were found in nine of 12 patients (75%). Sonography also revealed abnormalities not diagnosed by chest radiographs (n = 2). These findings could offer an complementary approach for evaluating sarcoidosis.

Sonographic lung surface evaluation in pulmonary sarcoidosis: preliminary results.

Fifty patients of pleural effusion were subjected to radiological and ultrasonic examinations The results of both examinations were compared and presented here The study was undertaken to assess the comparative efficacy of ultrasonography in diagnosing pleural effusion
