Pleural nodularity in lung ultrasound refers to the abnormal appearance of small, circumscribed lesions or lumps on the pleural lining. These nodules can be indicative of various underlying medical conditions, including inflammation, infection, or malignancy, such as metastatic disease or mesothelioma. Their detection is crucial for early diagnosis and treatment planning in respiratory medicine. Ultrasound…

Malignant pleural effusion (MPE) is a common complication of advanced cancer, where cancerous cells spread to the pleura, leading to fluid accumulation around the lungs. Ultrasound plays a crucial role in diagnosing MPE by identifying specific findings. Key malignant effusion findings on lung ultrasound include the presence of complex, septated effusions, nodularity or thickening of…

Chest wall invasion, in the context of lung pathology, refers to the extension of a primary lung tumor or metastatic disease directly into the surrounding chest wall structures. This critical finding indicates a more advanced stage of disease and can significantly impact treatment planning and prognosis. Ultrasound can play a role in assessing the extent…

Ultrasound can effectively identify rib fractures, particularly in the context of lung assessment. Key sonographic findings include cortical disruption, hematoma formation, and irregularity of the bony cortex. Visualization often reveals a step-off deformity or discontinuity, with associated overlying soft tissue swelling. When evaluating the lung, rib fractures can be a crucial finding as they may…

A lung recruitment maneuver (LRM) in medical and ultrasound contexts refers to a therapeutic intervention aimed at opening collapsed alveoli in the lungs, improving oxygenation and respiratory mechanics. Ultrasound monitoring plays a crucial role in real-time assessment during LRMs, allowing clinicians to visualize lung aeration changes, diaphragm movement, and pleural line characteristics, thereby optimizing the…

The "double lung point" in lung ultrasound is a critical sign indicating a resolving pneumothorax. It refers to the simultaneous visualization of both the absent lung sliding (indicating air in the pleural space) and the reappearance of lung sliding at different points on the same scan line. This dynamic finding signifies that the lung is…

Ventilator-induced changes in lung ultrasound (US) refer to alterations in lung tissue and pleura observed during mechanical ventilation. These changes, such as lung consolidation, atelectasis, or pleural effusions, can indicate complications like ventilator-induced lung injury (VILI) or barotrauma. Lung US is a rapid, non-invasive tool for monitoring these changes at the bedside, aiding in early…

"White lung" in medical imaging, particularly chest X-rays and ultrasound, refers to a diffuse, opaque appearance of the lung fields. This significant finding indicates widespread fluid accumulation or consolidation within the lung tissue, often seen in conditions like severe pneumonia, acute respiratory distress syndrome (ARDS), or pulmonary edema. It highlights a critical reduction in air-filled…

Post-thoracentesis evaluation in lung ultrasound is a crucial step to assess for potential complications after a thoracentesis procedure. This involves re-examining the pleural space for residual fluid, which could indicate incomplete drainage or reaccumulation. Additionally, it is vital to check for the presence of a pneumothorax, a common and potentially serious complication, by observing for…
