Brown adipose tissue represents about 1% of the adult body mass and decreases with age. Under variable circumstances, this amount changes, for example, with age or environmental conditions. Pathological states with hypersecretion of catecholamines can induce hypertrophy and hyperplasia in mature brown adipocytes. Consequently, this response can have imaging representation as pseudonodules, a pitfall in imaging interpretation, and may be confused with neoplastic involvement. A case of pheochromocytoma with brown fat stimulation and catecholamine cardiomyopathy is presented.
棕色脂肪组织约占成人体重的1%,并随年龄增长而减少。在不同情况下,这一数量会发生变化,例如随年龄或环境条件而改变。儿茶酚胺分泌过多的病理状态可诱导成熟棕色脂肪细胞肥大和增生。因此,这种反应在影像学上可表现为假结节,这是影像学解读中的一个陷阱,可能会与肿瘤累及相混淆。本文报告一例伴有棕色脂肪刺激和儿茶酚胺性心肌病的嗜铬细胞瘤病例。
