目的:分析9例女性低位小肠间质瘤(SISTs)的临床资料,探讨其误诊原因和超声诊断价值。方法:对1998~2005年我院收治并经病理证实的9例女性低位SISTs进行回顾分析。结果:9例女性低位SISTs患者被误诊为卵巢肿瘤3例,子宫浆膜下肌瘤5例,漏诊1例,患者平均年龄55岁,下腹部超声有异常包块者8例,未见包块者1例。包块呈低回声,边界清但不规则,有分叶,包块大小为23mm×24mm×24mm~75mm×66mm×75mm,彩超常规增益下少见彩色血流信号,彩色能量多普勒模式下血流信号较少。术中发现肿瘤位于小肠的8例,回盲部1例。免疫组化表型CD117阳性7例(77.8%),CD34阳性6例(66.7%)。病理诊断SISTs交界性1例,恶性8例。9例均行根治手术切除。结论:SISTs的诊断有赖于临床特征、影像学检查、免疫组化及病理检查相结合,由于超声检查无创、价廉,只要掌握好鉴别要点,应该是一种很好的筛查方法。
Objective: To analyze the clinical data of 9 cases of female patients with small intestinal stromal tumors (SISTs) and investigate the causes of misdiagnosis and the value of ultrasonic diagnosis. Methods: Nine cases of low grade SISTs admitted to our hospital from 1998 to 2005 and confirmed by pathology were retrospectively analyzed. Results: Nine patients with low grade SISTs were misdiagnosed as ovarian tumors in 3 cases, uterine fibroids in 5 cases, missed diagnosis in 1 case, patients with an average age of 55 years old, lower abdominal ultrasound with abnormal mass in 8 cases, no mass In 1 case. The mass was hypoechoic, the border was clear but irregular, with lobes. The size of the mass was 23mm × 24mm × 24mm ~ 75mm × 66mm × 75mm. Under color supernormal gain, rare color flow signals were found. The color Doppler blood flow Streaming signal less. Tumor found in the small intestine in 8 cases, 1 case of ileocecal. Immunohistochemical phenotype CD117 positive in 7 cases (77.8%), CD34 positive in 6 cases (66.7%). Pathological diagnosis of SISTs junctional in 1 case, malignant in 8 cases. All patients underwent radical resection. Conclusion: The diagnosis of SISTs depends on the clinical features, imaging examination, immunohistochemistry and pathological examination. Because ultrasound examination is noninvasive and inexpensive, it should be a good screening method as long as the key points of identification are mastered.
