CTICasesDystrophic Calcification from Rhabdomyolysis and Pulmonary Interstitial Emphysema

Imaging findings
The patient developed rhabdomyolysis and a CT for hypoxia revealed extensive calcification in his chest wall musculature. He also presented with pulmonary interstitial emphysema, presumably from barotrauma due to intubation, with clear examples visible on CT appearing as septal lines. There was no associated pneumomediastinum yet.
Key takeaways
Pulmonary interstitial emphysema can decompress promptly into the mediastinum, leading to substantial pneumomediastinum via the Macklin phenomenon. This case features both dystrophic calcification from rhabdomyolysis and interstitial emphysema.
