In a series of 125 patients examined ultrasonically for suspected abdominal aortic aneurysms, 15 patients (12%) had intraabdominal abnormalities unrelated to the aorta. In 12 of these patients, a retroperitoneal malignancy clinically mimicked an aneurysm. In the remaining three, other abnormalities were discovered in addition to an aneurysm. In one patient, a large uterine myoma was visualized; in another, large retroperitoneal lymph nodes subsequently proved to be lymphoma; in the third, enlarged lymph nodes in association with a carcinoma of the colon were discovered. Because of the high incidence of unsuspected findings, ultrasonography should become an essential part of the evaluation of this group of patients.
在对125例疑似腹主动脉瘤患者进行超声检查的系列病例中，15例（12%）患者存在与主动脉无关的腹内异常。其中12例患者，腹膜后恶性肿瘤在临床上酷似动脉瘤。其余3例患者，除动脉瘤外还发现了其他异常。1例患者可见巨大子宫肌瘤；另1例患者，后来证实肿大的腹膜后淋巴结为淋巴瘤；第3例患者，发现与结肠癌相关的肿大淋巴结。由于意外发现的发生率较高，超声检查应成为评估这类患者的重要组成部分。
