To describe the epidemiologic, clinical, and imaging features of cat-scratch disease (CSD) to facilitate prompt recognition and noninvasive diagnosis of this condition.
Eight otherwise healthy patients with pet cats presented with the subacute onset of epitrochlear, axillary, or groin masses. All underwent cross-sectional imaging with computed tomography (CT) (n = 1) or magnetic resonance (MR) imaging (n = 7). Five patients underwent radiography of the elbow.
In all patients, MR imaging and CT showed a poorly defined soft-tissue mass with extensive surrounding edema in an efferent lymphatic distribution. Radiography revealed only soft-tissue edema in two patients and an ill-defined soft-tissue mass with soft-tissue edema in three patients. Six patients underwent biopsy; the findings of all pathologic specimens supported the diagnosis of CSD. No patients underwent serologic evaluation. All patients were asymptomatic within 4 weeks of beginning antibiotic therapy.
CSD should be considered in all patients with upper extremity or head and neck adenopathy and a history of cat exposure. Although generally not required for diagnosis, cross-sectional imaging will reveal a mass with surrounding edema in an area of lymphatic drainage.
描述猫抓病（CSD）的流行病学、临床及影像学特征，以促进对此病的及时识别和无创诊断。
8名身体健康但养宠物猫的患者出现了滑车上、腋窝或腹股沟肿块的亚急性发作。所有患者均接受了计算机断层扫描（CT）（n = 1）或磁共振成像（MR）（n = 7）的横断面成像检查。5名患者接受了肘部X线摄影。
所有患者的MR成像和CT均显示出边界不清的软组织肿块，周围有广泛水肿，呈输出淋巴管分布。X线摄影仅显示2例患者有软组织水肿，3例患者有边界不清的软组织肿块伴软组织水肿。6名患者接受了活检；所有病理标本的检查结果均支持CSD的诊断。无患者接受血清学评估。所有患者在开始抗生素治疗后4周内均无症状。
所有上肢或头颈部淋巴结病且有猫接触史的患者均应考虑CSD。虽然诊断一般不需要，但横断面成像将显示在淋巴引流区域有一个伴有周围水肿的肿块。
