Cat-Scratch Disease (CSD) is an infectious disease that predominantly affects pediatric patients, usually ages 4-9 years old. The annual incidence is estimated at 4.5 patients per 100,000 population. CSD is primarily caused by B. henselae, an intracellular gram-negative bacillus; it is transmitted via scratch, lick, or bite from a cat. It presents with lymphadenopathy proximal to the site of inoculation; most commonly, this is axillary, epitrochlear, cervical, or inguinal lymphadenopathy. While CSD can be diagnosed clinically and has objective findings on histopathology, the imaging findings are unclear and have been debated in the literature. As such, we sought to clarify the multimodal imaging findings associated with CSD. We performed a review of the literature to highlight the existing radiological consensus. We also contribute several of our own new cases from our institution.
