为了探讨超声显像对肾上腺嗜铬细胞的诊断价值,现将我院1993年6月以来,经超声检查并经手术及病理证实的3例报告如下。 使用仪器为Aloka SSO—650型实时超声显像仪,探头频率为3.5MHz,病人取仰卧、侧卧或俯卧位腰部冠状前倾切面,最易显示肾上腺区病灶。 例1,男性,48岁,因阵发性头晕,胸闷1年,伴左上肢麻木1月拟诊高血压,颈椎病而入院。BP 22/14KPa。B超检查:在下腔静脉后方,右肾中上部的前方,探及2.5×2.3cm边界清楚、质地均匀的低回声团块。手术所见:右肾上腺中部一2×2cm肿块,部分位于下腔静脉后,质韧界清,与周围组织无粘连。病理:右肾上腺嗜铬细胞瘤。 例2,男性,58岁,因突发性晕厥、反复发作15年而入院。BP 19×16.5KPa。B超检查:在右侧肾上腺区探及6.0×4.8cm包膜完整的混合性团块,液性部分大小为4.6×2.2cm。B超诊断:右肾上腺占位病变——嗜铬细胞瘤。手术和病理诊断同B超。
In order to discuss the diagnostic value of ultrasound imaging for adrenal chromaffin cells, we have reported three cases of ultrasound examination, and confirmed by surgery and pathology since June 1993 in our hospital. The instrument used was the Aloka SSO-650 real-time ultrasound imaging system. The frequency of the probe was 3.5 MHz. The patient took the supine, lateral or prone position of the lumbar coronal anteversion plane and showed the adrenal lesions most easily. Case 1, male, 48 years old, due to paroxysmal dizziness, chest distress for 1 year, accompanied by numbness of the left upper extremity in January, was diagnosed with hypertension and cervical spondylosis and admitted to hospital. BP 22/14KPa. B-ultrasound: Behind the inferior vena cava, in front of the right middle and upper part of the right kidney, explore 2.5×2.3 cm hypoechoic mass with clear boundary and uniform texture. Surgical findings: A 2×2 cm mass in the middle of the right adrenal gland, partially located behind the inferior vena cava, with a clear mass and toughness, and no adhesion with surrounding tissues. Pathology: Right adrenal pheochromocytoma. Case 2, male, 58 years old, admitted to hospital because of sudden syncope, repeated attacks for 15 years. BP 19×16.5 KPa. B-ultrasonic examination: In the right adrenal area, a 6.0×4.8 cm coated mixed mass was probed. The liquid part size was 4.6×2.2 cm. B-diagnosis: right adrenal mass lesions - pheochromocytoma. Surgical and pathological diagnosis with B ultrasound.
