【摘要】：目的探讨总结成人Henoch紫癜的螺旋CT影像特点。方法回顾性分析20例Henoch紫癜患者螺旋CT表现,对肠壁病变范围、肠壁形态、肠管外脂肪间隙及肠系膜改变、肠腔内外伴发征象、强化表现及腹腔积液情况等分析总结。结果 20例Henoch紫癜患者中,单一部位受累11例,多部位受累9例。胃受累3例,十二指肠受累6例,空、回肠受累13例,结肠受累8例。18例病变肠管管壁弥漫增厚,其中10例肠壁环形增厚,解剖层次清晰;8例增厚肠壁解剖层次模糊。15例浆膜外肠系膜侧脂肪间隙密度增高。3例腹腔少量积液。10例行CT增强扫描患者中,8例显示肠壁全层弥漫强化;2例肠壁分层强化。3例结肠肠腔内积血。肠管3~7天肿胀减轻8例;肠管7~14天基本恢复正常17例;3例1个月后恢复。结果 Henoch紫癜的基本CT征象包括弥漫或多节段肠管均匀全层或环形分层增厚,弥漫全层或环形强化及浆膜外渗出。CT检查是Henoch紫癜诊断和复查的有效手段。
[Abstract]:Objective to investigate the spiral CT features of adult Henoch purpura. Methods the spiral CT findings of 20 patients with Henoch purpura were retrospectively analyzed. Results among the 20 patients with Henoch purpura, 11 had single site involvement, 9 multiple site involvement, 3 gastric involvement, 6 duodenal involvement, 13 emptying and ileal involvement. 8 cases of colon involvement. 18 cases of pathological changes of intestinal wall diffuse thickening, 10 cases of intestinal wall ring thickening, The anatomical level was clear in 8 cases with thickening intestinal wall. In 15 cases, the density of fat space in extraserous mesenteric side was increased in 3 cases. 3 cases with small amount of peritoneal effusion. 10 cases with CT enhanced scanning. 8 cases showed diffuse enhancement of the whole layer of intestinal wall in 2 cases. In 3 cases, hemorrhage in colon lumen was enhanced by stratification, and swelling of intestinal duct was alleviated in 8 cases in 3 days. Results the basic CT signs of Henoch purpura included diffuse or multisegmental homogeneous full-layer or annular thickening of intestinal canal. Diffuse or ring enhancement and extraserous exudation. Ct is an effective method for diagnosis and reexamination of Henoch purpura.
