Pheochromocytoma may rarely cause arterial dissection. Here the authors report a patient with pheochromocytoma complicated with vertebral artery dissection (VAD) and stroke.
A 48-year-old man presented with probable diagnosis of myocardial infarction. Following premedication with methylprednisolone for coronary artery angiography, he had unstable hypertension. Three days later, he had right cerebellar and left occipital lobe infarction in association with VAD. Urinary cathecolamines and MR scan of the abdomen suggested a diagnosis of phaeochromocytoma, which was later histopathologically confirmed.
This case is interesting in that there is no previous report of the combination of pheochromocytoma, VAD, and stroke. Awareness of the atypical clinical presentations of this tumor is important for definitive treatment.
嗜铬细胞瘤很少会导致动脉夹层。在此，作者报告一例患有嗜铬细胞瘤并伴有椎动脉夹层（VAD）和中风的患者。
一名48岁男性，初步诊断为心肌梗死。在冠状动脉造影术前使用甲泼尼龙进行预处理后，他出现了不稳定的高血压。三天后，他出现了与VAD相关的右小脑和左枕叶梗死。尿儿茶酚胺检查及腹部磁共振成像扫描提示嗜铬细胞瘤诊断，随后经组织病理学确诊。
该病例很有意思，因为此前尚无嗜铬细胞瘤、VAD和中风合并出现的报道。认识到这种肿瘤的非典型临床表现对于明确治疗很重要。
