摘要：
马拉科普拉克（malacoplakia）是一种罕见的慢性肉芽肿性疾病，常与大肠杆菌感染相关。我们描述了一例伴有大肠杆菌尿路感染的膀胱和输尿管马拉科普拉克的增强CT和FDG PET/CT结果。增强CT显示在膀胱和左侧输尿管内出现多个强化的壁结节，大小从几毫米到3.1厘米不等。输尿管结节显示出明显增强的FDG摄取，SUVmax值为20.4，组织病理学显示组织细胞、淋巴细胞和浆细胞浸润。版权所有©2023 Wolters Kluwer Health，Inc. 保留所有权利。
Malacoplakia is a rare chronic granulomatous disease and frequently associated with Escherichia coli infection. We describe the contrast-enhanced CT and FDG PET/CT findings in a case of bladder and ureteral malakoplakia with E. coli urinary tract infection. Contrast-enhanced CT showed multiple enhancing mural nodules in the bladder and left ureter, ranging from several millimeters to 3.1 cm. The ureteral nodules showed significantly increased FDG uptake with SUVmax of 20.4, due to histiocyte, lymphocyte, and plasma cell infiltrates revealed by histopathology.Copyright © 2023 Wolters Kluwer Health, Inc.
