We describe a patient with an unusual cause of internal carotid artery occlusion resulting in a stroke.
A 41-year-old woman presented with a typical acute right middle cerebral artery territory infarct. Her hematological and cardiological status was assessed, including all extracranial vessels. Carotid angiography and a biopsy were performed of the occluded right internal carotid artery and demonstrated a myxoma. Cardiac investigations to determine the source of the myxoma, including transthoracic and transesophageal echocardiograms, CT and yo-yo CT scans, and MRI of the heart, were normal. No residual tumor or potential source of the tumor was found.
The cause of stroke was a myxomatous occlusion of the right internal carotid artery. An entire cardiac tumor may have embolized with no detectable residual tumor in the heart; alternatively, a myxoma may have originated as a primary tumor in the carotid artery. To our knowledge, no primary myxoma has been reported to have originated in a blood vessel.
我们描述了一例因颈内动脉闭塞导致中风的不寻常病因的患者。
一名41岁女性出现典型的急性右大脑中动脉供血区梗死。对其血液学和心脏状况进行了评估，包括所有颅外血管。对闭塞的右侧颈内动脉进行了颈动脉血管造影和活检，结果显示为黏液瘤。为确定黏液瘤的来源进行的心脏检查，包括经胸和经食管超声心动图、CT和螺旋CT扫描以及心脏MRI，均正常。未发现残留肿瘤或肿瘤的潜在来源。
中风的病因是右侧颈内动脉黏液瘤性闭塞。整个心脏肿瘤可能已经发生栓塞，而心脏中未检测到残留肿瘤；或者，黏液瘤可能起源于颈动脉的原发性肿瘤。据我们所知，尚未有原发性黏液瘤起源于血管的报道。
