Introduction: The frequency of drowning increases with the warming of the weather, especially in summer months. In this paper, the clinical features, radiological imaging and laboratory values of three patients who presented to the emergency department due to near-drowning are discussed comparatively. Case Report: In Case 1 and 3, advanced life support was applied at the scene and spontaneous circulation was restored. Case 2 presented with the complaint of dyspnea. Cases 1 and 3 died after being admitted to the intensive care unit, while Case 2 was discharged with full recovery. Conclusion: Diffuse ground-glass opacities were detected in the early thorax computed tomography imaging of all three cases. In addition, there were early increases in laboratory values in all three cases, with the highest increases being observed in aspartate aminotransferase, alanine aminotransferase and creatinine kinase values. This suggests that tissue perfusion disorder develops in the early period.
