Imaging of granulomatous lesions of the neck in children

Cervical lymphadenopathy is the most common presentation of granulomatous inflammation of the neck in children and is usually caused by NTM infection. Although certain granulomatous infections have characteristic imaging features, there is considerable overlap in the imaging appearance of the various disorders. The diagnosis is usually based on a combination of clinical features, histopathologic examination, serologic tests, and culture results.
