A multi-panel medical image sequence documenting the progression and resolution of a right-sided pneumothorax. Panel A presents axial Thorax Computed Tomography (TCT) lung window slices showing a significant right pneumothorax, characterized by a large, dark, air-filled pleural space (radiolucency) causing collapse of the right lung toward the mediastinum; the left lung remains fully expanded with normal density. Panel B is a Posteroanterior (PA) chest X-ray taken after tube thoracostomy, showing the right lung successfully re-expanded with the chest tube in situ. Panel C displays a follow-up chest X-ray after removal of the chest tube on the fifth day, maintaining full lung expansion and clear costophrenic angles. Panel D shows a follow-up axial TCT image two weeks post-discharge, confirming complete resolution of the pneumothorax with bilateral symmetric lung expansion and normal lung parenchyma. This sequence illustrates the clinical management of a spontaneous pneumothorax in the context of COVID-19 infection, from acute presentation to complete recovery.

Educational clinical image set documenting a secondary pneumothorax in a patient with chronic hypersensitivity pneumonitis. Panel (a) is a posterior-anterior (PA) chest X-ray showing a large right-sided tension pneumothorax with significant mediastinal shift to the left and complete collapse of the right lung. Panel (b) is a follow-up chest X-ray post-thoracic drainage showing a visible chest tube and a persistent, mild residual pneumothorax cavity (indicated by yellow arrowheads) along the right lateral chest wall. Both radiographs reveal underlying diffuse reticular opacities consistent with interstitial lung disease. Panel (c) is an axial non-contrast chest CT scan (lung window) demonstrating extensive bilateral subpleural honeycombing and ground-glass opacities characteristic of advanced pulmonary fibrosis. The CT also captures the collapse of the right middle and lower lobes and an associated pleural air space. The series demonstrates the complication of intractable air leak in the context of advanced fibrotic lung disease.

This composite figure demonstrates diagnostic imaging findings of bullous lung disease and pneumothorax in a patient with COPD. Image A is a frontal chest X-ray on presentation showing multiple large, thin-walled, hyperlucent areas consistent with giant bullae, particularly prominent in the lower zones, and a concomitant mild left-sided pneumothorax identified by a peripheral lucency and lack of lung markings. Image B is a coronal reformatted CT scan of the chest, providing high-resolution visualization of the lung parenchyma. It reveals extensive emphysematous changes and multiple, well-defined, thin-walled air-filled bullae of varying sizes occupying significant portions of both hemithoraces, with clear demarcation between the bullae and remaining compressed lung tissue. Image C is a follow-up chest X-ray taken 10 days later, showing stable appearance of the giant bullae but interval improvement and resolution of the previously seen left-sided pneumothorax, with better expansion of the underlying lung. The series highlights the importance of distinguishing between giant bullae and pneumothorax in patients with advanced obstructive lung disease.

This composite educational image illustrates the genetic and radiological manifestations of Primary Ciliary Dyskinesia (PCD) in a pediatric patient. Panel (A) presents a family pedigree showing an autosomal recessive inheritance pattern. Panel (B) is an AgileMultiIdeogram showing a region of homozygosity (ROH) on chromosome 15. Panel (C) is a posteroanterior (PA) chest X-ray demonstrating a 'flat-waist sign' and a triangular retrocardiac opacity, classic indicators of left lower lobe (LLL) collapse. Panels (D) and (E) are axial CT chest scans in soft-tissue and lung windows, respectively. These diagnostic images reveal bilateral pathology, specifically highlighting subsegmental collapse in both the right and left lower lobes (indicated by red and yellow arrows). The images collectively demonstrate the secondary pulmonary complications of PCD, such as chronic atelectasis and lobar collapse, essential for clinical diagnosis and management in pediatric pulmonology and medical genetics.

This composite figure displays diagnostic imaging of chest pathologies. Image C is an anteroposterior chest X-ray demonstrating a significantly elevated left hemidiaphragm caused by multiple dilated, gas-filled bowel loops within the upper abdomen, consistent with an opioid-induced ileus. Monitoring leads and a central line are visible. Image D is an axial CT scan of the chest (lung window) showing a dense area of consolidation and volume loss in the left lower lobe, indicative of collapse and persistent pneumonia or aspiration. The right lung remains clear. These images illustrate common secondary pulmonary and gastrointestinal complications in trauma patients with spinal cord injuries, emphasizing the impact of abdominal distention on diaphragmatic position and the radiological presentation of lobar consolidation.

Frontal chest x-ray demonstrating multi-lobar pathology in the left lung with associated mediastinal changes. Key findings include a dense opacity in the left lower lobe consistent with atelectasis (indicated by red arrows) and reticular, net-like infiltrates throughout the left upper lobe (circled in red), suggesting an alveolo-interstitial pneumopathy. There is a noticeable ipsilateral shift of the mediastinum towards the left, signifying volume loss. The right lung appears hyperinflated, providing a compensatory response to the left-sided collapse. Additionally, the image shows evidence of extraskeletal calcification near the tracheal bifurcation and possible heterotopic bone formation in the right laterodorsal region. These findings are highly relevant for diagnosing complex systemic conditions manifesting with respiratory impairment and progressive ossification, such as fibrodysplasia ossificans progressiva (FOP).
