CTICasesCocaine-Induced Pulmonary Hemorrhage
Imaging findings
Chest radiograph and CT show bilateral, central, confluent ground-glass opacities and alveolar consolidations with relative subpleural/peripheral sparing, which cleared within 24 hours with supportive care.
Key takeaways
Smoking cocaine ('crack lung') can cause acute lung injury and diffuse alveolar hemorrhage. The classic imaging presentation is central consolidative opacity with peripheral sparing, which improves rapidly with supportive management. In contrast to cardiogenic edema, patients typically have normal troponin levels and cardiac function.
