This composite figure displays a series of thoracic and abdominal imaging modalities illustrating Situs Inversus Totalis (SIT) and postoperative pulmonary complications. Image A is a preoperative posterior-anterior chest X-ray clearly demonstrating dextrocardia. Images B and C are coronal sections of a contrast-enhanced thoracoabdominal CT scan. Image B shows the heart apex pointing to the right (dextrocardia), with the liver in the left hypochondrium and the stomach in the right hypochondrium, diagnostic of SIT. Image C, a posterior coronal section, reveals bilateral posterobasal consolidations, basal atelectasis, and incipient bilateral pleural effusion. Images D and E are postoperative serial chest X-rays. Image D, taken 48 hours post-conservative management, shows significant but incomplete improvement with a persistent right-sided pleural effusion causing basal opacity. Image E is a follow-up X-ray showing full resolution of the atelectasis and pleural effusion, with clear lung fields and sharp costophrenic angles. The series provides an educational overview of the radiological presentation of complete organ transposition and the progression/resolution of secondary pulmonary atelectasis and effusion.

A multi-panel medical comparison chart featuring longitudinal chest X-rays (a, c, e) and corresponding axial chest computed tomography (CT) scans (b, d, f) illustrating the clinical progression and resolution of polyserositis associated with Meigs’ syndrome. Panel (a) shows a posteroanterior chest X-ray with cardiac enlargement and a right-sided pulmonary nodule (arrow). The adjacent CT scan (b) confirms a significant, large-volume pericardial effusion. Panel (c) demonstrates clinical progression on X-ray with a large right-sided pleural effusion and blunting of the left costophrenic angle, indicating bilateral involvement. The corresponding CT scan (d) shows a partial decrease in the pericardial effusion but reveals accompanying pleural effusions. Panels (e) and (f) display follow-up imaging eight months after surgical removal of an ovarian fibroma, showing complete resolution of the cardiomegaly, pleural effusions, and pericardial fluid. This clinical series highlights the diagnostic hallmarks of Meigs’ syndrome, characterized by the triad of benign ovarian tumor, ascites, and pleural/pericardial effusions that resolve following tumor excision.

This composite educational image illustrates the progression and partial resolution of pulmonary pathology in a patient with COVID-19 ARDS and secondary fungal infection. Panel 1 (Day 1) shows an axial chest CT scan section demonstrating localized ground-glass opacities (GGOs) primarily in the posterior aspect of the left lower lobe. Panel 2 (Day 8) is an anteroposterior (AP) chest X-ray revealing significant disease progression, characterized by extensive bipulmonary confluent densities and signs of a slight bilateral pleural effusion, consistent with peak Acute Respiratory Distress Syndrome (ARDS) manifestation. Panel 3 (Day 22) is a follow-up AP chest X-ray showing slight regression of the bilateral confluent opacities and a reduction in the volume of the left pleural effusion. This temporal comparison highlights common radiological patterns in viral pneumonia, including the transition from focal ground-glass findings on CT to diffuse consolidation on X-ray, and subsequent monitoring of treatment response or secondary complications.
