The purpose of this exhibit is: 1. To review the thoracic CT findings in severe drowning 2. To review the postmortem CT findings in drowning victims 3. To correlate the imaging features with the clinical presentation  

1. Definition and pathophysiology of drowning 2. Clinical evaluation of severity in drowning victims: a classification system of six grades 3. Thoracic CT findings after drowning - Lung opacities: reflect aspiration and pulmonary edema A. Diffuse ground-glass opacities (GGO) B. Air-space consolidation: seen in severe drowning C. Multiple lobular opacities: the most common pattern after drowning D. Interlobular septal thickening: reflects pulmonary edema - Pleural effusion: seen in severe drowning 4. Postmortem CT findings after drowning - Fluid collection in airways, pan-sinus fluid, mastoid cell fluid - Cardiopulmonary resuscitation (CPR) related findings (intravascular gas, rib fracture)　 - Postmortem changes (hypostasis, hyperattenuating aortic wall, and dilatation of the heart) 5. Pitfalls - Decompression disease - Immersion pulmonary edema (IPE) - Pulmonary edema due to airway obstruction
