A 44-year-old woman was admitted to our hospital with altered mental status and weakness in the left upper and lower limbs. A brain magnetic resonance imaging indicated multiple cerebral infarctions in the bilateral frontal and parietal lobes and in the left occipital lobe. Magnetic resonance angiography indicated overall arterial wall irregularity and stenosis. An electrocardiogram showed negative T waves, troponin I was elevated at 0.60 ng/mL, and an echocardiogram showed severe hypokinesis, leading to a diagnosis of ischemic heart disease; however, no stenosis was found at cardiac catheterization. No other etiology for the angiopathy could be found. Whole-body computed tomography demonstrated an adrenal tumor and urinary catecholamine levels were elevated. Following excision of the adrenal tumor, a diagnosis of pheochromocytoma was made. Postoperatively, the patient's arterial stenosis and cardiac abnormalities improved. It was hypothesized that the patient's cardiomyopathy and vasospasm were secondary to excessive catecholamine secretion from the pheochromocytoma.
一名44岁女性因精神状态改变及左上肢和下肢无力入院。脑部磁共振成像显示双侧额叶、顶叶及左侧枕叶多发脑梗死。磁共振血管造影显示动脉壁整体不规则及狭窄。心电图显示T波倒置,肌钙蛋白I升高至0.60 ng/mL,超声心动图显示严重运动减弱,诊断为缺血性心脏病;然而,心导管检查未发现狭窄。未发现血管病变的其他病因。全身计算机断层扫描显示肾上腺肿瘤,尿儿茶酚胺水平升高。肾上腺肿瘤切除术后,诊断为嗜铬细胞瘤。术后,患者的动脉狭窄和心脏异常情况有所改善。据推测,患者的心肌病和血管痉挛继发于嗜铬细胞瘤分泌过多的儿茶酚胺。
