title: Posterolateral hypertrophic cardiomyopathy: a rare, but clinically significant variant of hypertrophic cardiomyopathy.
abstract: Posterolateral hypertrophic cardiomyopathy (HCM) is a rare variant of HCM. Segmental HCM is seen in 12% of cases of HCM. Among the patterns of segmental HCM, posterolateral HCM is the least common type. Our case of an 18-year old male documents this unusual type of cardiomyopathy. In this form of HCM, left ventricular thickness and the extent of hypertrophy might be underestimated by 2-dimensional echocardiography. This case illustrates the echocardiographic and pathologic features of posterolateral HCM.
