Abstract

Head and neck cancer ranks sixth among all cancers worldwide.LNs levels can be categorized and used for staging and treatment planning of tumors. Metastasis of the LN decreases survival from HNSCC by 50%.
Contrast-enhanced CT is considered a noninvasive method for metastatic cervical nodes detection, as it yields information about size, shape, and morphology with high anatomic resolution. PET/CT is more preferable than CT for evaluating cervical nodes metastasis because morphological criteria of CT for cervical lymph nodes metastasis diagnosis has limited value.
According to their size, shape, morphology, margins, arrangement, and distribution, abnormal LN are categorized. Metastatic disease can be diagnosed using a variety of criteria. If there is central necrosis or extracapsular dissemination, regardless of size, or if the shortest axial diameter in the jugulodigastric nodes is 11mm and 10mm in other cervical areas, the jugulodigastric LN are considered metastatic. Clustering sign is more common in head and neck carcinoma, primarily SCC.
