CTICasesHypertrophic Cardiomyopathy (HCM)

Imaging findings
Cardiac MRI revealed striking, mass-like myocardial thickening of 4.5-5 cm, predominantly involving the mid-cavity and apical septum of the left ventricle, with relative sparing of the base. Despite the severe hypertrophy, there was no systolic anterior motion (SAM) of the mitral valve or outflow tract obstruction. Prominent, diffuse hazy delayed enhancement was noted within the hypertrophied myocardial segments.
Key takeaways
Hypertrophic cardiomyopathy (HCM) can manifest with extreme myocardial thickening and varied distribution patterns, often showing prominent delayed enhancement. Screening of family members is crucial given the genetic predisposition and risk of sudden cardiac death.
