Necrotic lymphadenitis (arrows) misdiagnosed as suppurative lymphadenitis in a teenager. Lymphadenitis is seen on the axial fat-suppressed T2-weighted image (a) and poor enhancement on the post-contrast T1-weighted image (c) compared with the pre-contrast image (b). ADC shows restricted diffusion (d). The finding was misinterpreted as suppurative lymphadenitis; however, at later time points, delayed enhancement is seen (e, f), ruling out suppuration. Surgery found necrosis, but no pus. Image modified from ref. [8]
