Cardiac positron-emission tomography images with an amyloid-specific tracer in familial transthyretin-related systemic amyloidosis

摘要

We report the case of a 32-year-old man who had suffered from orthostatic syncope and body weight loss since he was 27 years old. As years passed by, he also showed muscle weakness and abnormal sensations in both legs, hyporeflexia in 4 limbs, and autonomic failure (impotence, urinary and fecal incontinence, and edema in lower limbs) suggesting the presence of peripheral somatic and autonomic poly neuropathy. His mother, mother's father, and mother's paternal aunt also had similar symptoms.
