胃癌术后切口异位骨化的超声诊断与病理对照分析

Ultrasonic diagnosis of heterotopic ossification following surgery for gastric carcinoma and its correlation with pathological findings

目的探讨胃癌术后切口异位骨化的声像图特征及与病理组织学的关系.方法对14例胃癌术后切口异位骨化患者的声像图进行回顾性分析,并将诊断结果与手术及病理结果进行对比分析.结果14例患者中,3例为Ⅰ期病变,超声显示为较均匀的低回声肿块;6例为Ⅱ期病变,超声显示为不均匀低回声,内部可见环状强回声,形似肋骨;3例为Ⅲ期病变,超声显示为不规则结节状强回声,伴有明显声影.2例超声首次检查误诊,后经手术病理或超声随访证实Ⅱ期和Ⅲ期病变各1例.3期病变各有不同的病理改变.结论超声有助于对本病的诊断及鉴别诊断,能为临床选择治疗方案和评估预后提供依据.

Objective To investigate the gray scale and color Doppler imaging of heterotopie ossification in patients undergoing surgery for gastric carcinoma and its histopathologic correlation, Methods The ultrasound findings of 14 patients with heterotopic ossification following surgery for gastric carcinoma were retrospectively analyzed , The results were compared with the surgical or pathological findings . Results Among the 14 cases, 3 were classified as typeⅠ, revealing homogeneous hypoechoic masses on ultrasonography; 6 were as type Ⅱ , showing heterogeneous hypoechoic masses with costa-shaped calcification ; and 3 were as type m, showing irregular ossified heterogeneous echogenic masses with obvious shadow. The remaining 2 cases were initially misdiagnosed and subsequently diagnosed as type II （ 1 case） and type Ⅲ （ 1 case） by pathology or follow-up ultrasound. The 3 types had different pathological variations. Conclusions Ultrasonography is helpful for the diagnosis and differential diagnosis of this disease. It can also provide evidence for selection of the clinical therapeutic regimen and predict the patient＇ s prognosis.
