Giant cell myocarditis in a middle-aged male: features in CMR.

Giant cell myocarditis (GCM) is a rare, rapidly progressive inflammatory cardiomyopathy that often presents with fulminant heart failure. We report a 52-year-old male with acute chest pain and cardiogenic shock, with cardiac MRI and biopsy confirming GCM. Early recognition and timely immunosuppressive therapy were critical to management and improving clinical outcomes.
