Dactylitis refers to a global swelling of a finger or a toe giving it a clinical sausage-shape presentation. It is an extremely suggestive symptom as it guides the rheumatologist towards a shortlist of diagnoses. However, radiologists are less familiar with dactylitis. The aim of this review is to detail and illustrate the main causes of dactylitis using standard X-ray imaging, ultrasound, computed tomography and magnetic resonance imaging in order to make radiologists more familiar with this symptom by illustrating the various conditions that are associated with dactylitis including infection, peripheral spondyloarthritis, sarcoidosis, microcrystalline deposition, osteoid osteoma, and sickle cell disease.
指（趾）炎是指手指或脚趾的全面肿胀，使手指或脚趾呈现出典型的腊肠样外观。这是一种非常具有提示性的症状，因为它可以帮助风湿病学家缩小诊断范围。然而，放射科医生对指（趾）炎的了解较少。本综述的目的是详细描述和说明使用标准 X 射线成像、超声、计算机断层扫描和磁共振成像诊断指（趾）炎的主要原因，以便通过说明与指（趾）炎相关的各种疾病，包括感染、外周脊柱关节炎、结节病、微晶体沉积、骨样骨瘤和镰状细胞病，使放射科医生更加熟悉这一症状。
