Three patients presented with a non-thrombocytopenic purpuric rash on their upper and lower limbs, abdominal pain, diarrhoea, and arthralgia. Grey scale ultrasound showed abnormally thickened walls of the small bowel. Colour Doppler showed blood flow signals in the diseased bowel wall in all patients. Subsequent barium and endoscopic studies showed oedematous bowel loops with petechial lesions. Biopsy from the purpuric rash of the skin demonstrated vasculitis of subdermal small vessels. The clinical diagnosis of Henoch-Schönlein purpura was made in each case. This paper describes the efficacy of grey scale and colour Doppler ultrasonography in the assessment of the small bowel involvement of Henoch-Schönlein purpura.
三名患者出现上下肢非血小板减少性紫癜皮疹、腹痛、腹泻和关节痛。灰阶超声显示小肠壁异常增厚。彩色多普勒显示所有患者病变肠壁内有血流信号。随后的钡剂和内镜检查显示肠袢水肿并有瘀点病变。皮肤紫癜皮疹活检显示皮下小血管血管炎。每例均作出过敏性紫癜的临床诊断。本文描述了灰阶和彩色多普勒超声在评估过敏性紫癜小肠受累情况方面的有效性。
