Radiographs of the stomach showed narrowing of the antrum, caused by toxoplasmosis, in a patient with acquired immunodeficiency syndrome (AIDS). A biopsy specimen demonstrated numerous cysts containing Toxoplasma gondii and many free trophozoites. A subsequent brain scan, obtained with computed tomography, showed multiple enhancing lesions throughout the cerebrum, cerebellum, and basal ganglia that were characteristic of toxoplasmosis. Radiographic abnormalities of the stomach are not uncommon in patients with AIDS. They are associated with infections such as cryptosporidiosis and cytomegalovirus and neoplasms such as Kaposi sarcoma and malignant lymphoma. To the authors' knowledge, this is the first reported case of toxoplasmosis involving the stomach.
一名获得性免疫缺陷综合征（艾滋病）患者的胃部X光片显示，胃窦因弓形虫病而变窄。活检标本显示有许多含有刚地弓形虫的囊肿和许多游离的滋养体。随后通过计算机断层扫描进行的脑部扫描显示，大脑、小脑和基底神经节有多处强化病变，这是弓形虫病的特征。胃部的影像学异常在艾滋病患者中并不罕见。它们与隐孢子虫病和巨细胞病毒等感染以及卡波西肉瘤和恶性淋巴瘤等肿瘤有关。据作者所知，这是首例报告的累及胃部的弓形虫病病例。
