title: Fat streak in the middle layer of the left ventricular myocardium in a patient with dilated cardiomyopathy: findings of multidetector CT and MR imaging.
abstract: We report a case of streaky fat deposition and late hyperenhancement in the middle layer of the left ventricular myocardium detected on computed tomography coronary angiography and cardiac magnetic resonance imaging in a patient with dilated cardiomyopathy. CT revealed multiple curvilinear streaks of hypoattenuating foci involving the middle layer of the LV myocardium, with a mean attenuation value of -70 HU, comparable to that of fat. Late mid-wall hyperenhancement foci were noted in the fatty deposition sites of the left ventricle wall on delayed contrast-enhanced cardiac MRI. However, an area of late mid-wall hyperenhancement was smaller than that of fat deposition.
