摘要

我们报告了一例 67 岁不吸烟女性的病例,她在 24 岁时被诊断出患有高血压,并伴有慢性肾病和高血压性心脏病。胸部 CT 意外发现腹主动脉旁有一个病灶(16x14x23mm)。最初怀疑是副神经节瘤,随后的核磁共振检查也没有排除这一可能性。尿液分析显示甲肾上腺素正常,嗜铬粒蛋白-A水平略有升高。在 VATs 手术过程中,发现降主动脉膈沟处的临膜层下方有 "隆起"。通过打开临膜,发现并切除了一个中心呈结节状的脂肪瘤病变。最终的组织病理报告证实了淋巴结的诊断,未提示肿瘤。目前,手术 12 个月后,患者在胸外科门诊接受监测,情况良好。尽管没有发现任何神经内分泌成分,但患者的动脉高血压有明显好转的临床症状。

An Unusual Location for a Lymph Node.

We report a case of a 67-years old non-smoking female diagnosed with hypertension when 24-years-old and complicated with chronic kidney and hypertensive heart diseases. On CT-Chest an incidental discovery of a lesion (16x14x23mm) adjacent to the abdominal aorta was made. Initially suspected to be paraganglioma, a hypothesis which the subsequent MRI did not exclude. Urine analysis showed normal Metanephrine with slightly elevated Chromogranin-A levels. During VATs-procedure "bulging" below the adventitial layer of the descending aorta at the level of the diaphragmatic gutter was identified. By opening the adventitia, a lipomatous lesion with a nodular, consistent center was identified and excised. Final histopathological report confirmed the diagnosis of lymph node not suggestive of neoplasia. Currently, 12 months after the surgery, the patient's condition is good being under surveillance in the Thoracosurgical Outpatient Clinic. Despite not having identified any neuroendocrine component, the patient had clinical signs of clear improvement of arterial hypertension.
