Fig 1.
A 54-year-old male patient with right tongue base oropharyngeal squamous cell carcinoma and necrotic nodal metastasis.
(A) T1-weighted, (B) fat-suppressed T2-weighted, and (C) contrast-enhanced fat-suppressed T1-weighted MRI images show an enlarged necrotic lymph node (arrow) in the right neck level IIA with irregular walls and central complex fluid-like content. (D) Contrast-enhanced fat-suppressed T1-weighted MRI three months after completion of chemoradiotherapy shows a residual necrotic node (arrows). Subsequent echo-guided fine needle aspiration cytology yielded metastatic carcinoma. The patient also experienced lung metastasis at a later date.

A 46-year-old male patient with left tongue base oropharyngeal squamous cell carcinoma and cystic nodal metastasis.
(A) T1-weighted, (B) fat-suppressed T2-weighted, and (C) contrast-enhanced fat-suppressed T1-weighted MRI images show an enlarged cystic lymph node (arrow) in the left neck level IIA with a thin, well-defined smooth margin, and central homogeneous fluid content. (D) T1-weighted MRI three months after completion of chemoradiotherapy shows regression of the neck node. The patient was disease-free during three years of clinical and imaging follow-up.
