Hypertrophic cardiomyopathy--two atypical forms diagnosed by cardiac CT.

Hypertrophic cardiomyopathy is a relatively common genetic disease (prevalence of 0.2%), with a clinical spectrum that ranges from absence of symptoms to presentation as sudden cardiac death. Atypical forms are a diagnostic challenge and recent cardiac imaging techniques, such as cardiac CT and magnetic resonance imaging, can make an important contribution. We present a review of this disease based on two case reports.
