Purpose Generally, cervical lymphadenopathy is a benign, self-limited, and reactive process that is frequently encountered, especially in the pediatric population. However, when present in the setting of a neoplastic process, cervical lymphadenopathy is an important prognostic factor that can alter patient management. Determining the etiology of cervical lymphadenopathy is as essential as its detection. Etiologies include infection, granulomatous disease, malignancy, autoimmune disorders, iatrogenic causes, and miscellaneous or unusual conditions. Careful attention to clinical history and laboratory findings and the use of appropriate radiological imaging is crucial to obtaining the correct diagnosis. A variety of cases, including benign and malignant processes, will be presented along with explanations that emphasize the relevant features, imaging findings, and management (when appropriate) for each entity. Rare entities including but not limited to Rosai-Dorfman Disease, Kikuchi-Fujimoto Disease, Kimura Disease, and amyloidosis, as well as more common entities such as mononucleosis, sarcoidosis, leukemia/lymphoma, and metastatic pharyngeal mucosa and thyroid tumors will be presented in this exhibit. Materials and Methods - To highlight key imaging features of entities that can result in cervical lymphadenopathy. - To review the categories of conditions that can lead to cervical lymphadenopathy. - To emphasize the relevant clinical history and ancillary imaging findings that may aid in making the correct diagnosis.
