艾滋病合并腹部感染的影像学表现

The Imaging Feature of AIDS with Abdominal Infections

目的初步探讨艾滋病(AIDS)合并腹部感染的影像学特点。资料与方法经病理及实验室检查证实的6例AIDS患者分别为AIDS合并腹腔淋巴结核、脾结核、肠结核、腹膜后马尔尼菲青霉菌病、阿米巴肝脓肿、化脓性胆管炎,全部病例均有完整的CT影像资料。结果腹腔淋巴结核表现为腹腔内及腹膜后肿大淋巴结影,中心为低密度,边缘环形强化,脾结核患者脾内散在分布小结节状低密度病灶,肠结核表现为肠壁增厚,管腔狭窄。阿米巴肝脓肿患者肝内囊性病变,边缘强化,化脓性胆管炎患者肝内、外胆管扩张,管壁增厚,管腔内积气。马尔尼菲青霉菌患者腹膜后多组肿大淋巴结,局部融合成团块。结论影像检查是发现和评价AIDS腹部合并症的有效方法,可为早期诊断及时治疗提供依据,定性诊断有赖于穿刺活检及实验室检查。

Objective To collect cases of AIDS with abdominal infections,evaluate its features of imaging. Materials and Methods 6 cases of AIDS with abdominal infections were proved. There are 3 cases of tuberculosis, affected retroperitoneal lymph node, spleen and intestine respectively. Another 3 cases infection is hepatic ameba abbess, Penicilium marneffei of retroperitoneal lymph node and cholangitis. All patients had imaging, and analyzed by three of the radiologists, disa- greement among them was discussed and a consensus reached. Results Radiological manifestations of abdominal tuberculosis is enlarged lymph nodes peripheral rim enhancement with central low-attention, scattered low-attention in spleen and thickening of intestine wall. Ameba abbess, Penicilium marneffei and cholangitis manifested as cyst lesion with rim enhancement in the liver, enlargement retroperitoneal lymph nodes,thickening and distension of biliary tract respectively. Conclusion Imaging is valuable for diagnosis and differential diagnosis of AIDS with abdominal infections, and biopsy and Results of lab is needed to confirm the diagnosis.
