An Uncommon Variant of an Uncommon Disease: A Caucasian Adolescent with Apical Hypertrophic Cardiomyopathy Diagnosed with Myocardial Perfusion Imaging.

Apical hypertrophic cardiomyopathy (ApHCM) is a subtype of HCM. This variant is more common in the Asian population when compared to North American patients. Patients may present with arrhythmias, heart failure, myocardial infarction, chest discomfort, fatigue, and presyncope or syncope.

Implications of unexpected diffuse lung uptake on a 99mTc-sestimibi parathyroid scan.

Diffuse (99m)Tc-sestimibi uptake in the lungs is a sign of serious pathology and merits further work-up. We present a case in which diffuse lung uptake was incidentally found on a parathyroid scan.

18F-FDG PET assessment of Lewy body dementia with cerebellar diaschisis.

Alzheimer disease and Lewy body dementia are the 2 most common causes of dementia. Each disease has distinctive regional metabolic reduction patterns on (18)F-FDG PET. In this report, we present a rare case of an elderly man with dementia whereby (18)F-FDG PET clearly showed Lewy body disease with crossed cerebellar diaschisis.
