We present a case of a 77-year-old man who reported 5 months of syncopal episodes. He was found to have diffuse large B-cell lymphoma encasing the left internal carotid artery but not impeding blood flow. The syncopal episodes resolved after his first cycle of chemotherapy. Recurrent syncope in non-cardiac lymphomas and other head and neck masses is exceedingly rare and may be due to reflex syncope prompted by carotid baroreceptor activation. There are 11 previously described cases of recurrent syncope associated with non-cardiac lymphoma. In all cases, lymphadenopathy abutting the carotid artery was present and the syncopal episodes resolved with treatment. Our case illustrates that malignancy should be considered in patients with unexplained recurrent syncope.
我们报告了一例 77 岁男性,他自述有 5 个月的晕厥发作史。检查发现弥漫性大 B 细胞淋巴瘤包绕左侧颈内动脉,但未导致血流受阻。首次化疗后,晕厥发作得到缓解。非心脏性淋巴瘤和其他头颈部肿块导致的复发性晕厥极为罕见,可能是由于颈动脉压力感受器激活引起的反射性晕厥。此前已有 11 例与非心脏性淋巴瘤相关的复发性晕厥的描述性病例。在所有这些病例中,均存在紧邻颈动脉的淋巴结病,且晕厥发作在治疗后得到缓解。我们的病例表明,对于不明原因复发性晕厥的患者,应考虑恶性肿瘤的可能。
