Feinstein Cervical lymph node metastases refer to regional nodal involvement by cancer in the head and neck, most commonly due to squamous cell carcinoma originating from the aerodigestive tract or skin. The presence of necrotic/cystic areas is also highly predictive of metastatic disease compared to benign nodes in patients with head and neck cancer 5. The deep cervical chain of nodes follows the internal jugular vein so, after contrast administration, lymphadenopathy can often be seen against the lucent (fatty connective) tissue surrounding the common carotid artery and internal jugular vein. The major difference between the two surrounds categorisation of a node measuring 3 cm or less with … Lymphatic drainage is multidirectional and initial lymph drainage is to perithyroid lymph nodes then onto prelaryngeal, pretracheal and paratracheal nodes (level 6 lymph nodes).

Various criteria have been proposed to predict metastatic involvement of a cervical lymph node on CT and MR: Some studies compared the relative value of these different features, finding that minimal axial (short-axis) diameter was a better classifier for metastatic disease than maximal axial (long-axis) diameter or longest coronal (longitudinal) diameter 1,5. Radiologic detection of cervical lymph node metastases is important for clinical staging and planning of surgery and radiotherapy. The internal jugular vein (IJV) is the major venous return from the brain, upper face and neck.. These named groups overlap with the cervical lymph node levels, which are numbered.

Shape Benign nodes are oval or elongated while malignant nodes are often described as rounded (see figure 1). 2. Although often considered nonspecific, cervical lymph node imaging features, in conjunction with clinical presentation and related head and neck imaging findings, can aid in determining the cause of the abnormality. The cervical lymph nodes are tiny glands located in the sides and back of the neck. Gross anatomy.

The midline of the trachea serves as the border between stations 1R and 1L. In addition, increase in size is not always pathologic; some nodes are bigger than others normally (e.g compare jugulodigastric nodes to mesenteric nodes), and reactive nodes are a healthy response and do not imply pathology of the node it… level Ia (submental nodes): anteromedial between the anterior bellies of both digastric muscles; level Ib (submandibular nodes): posterolateral to the anterior belly of the digastric muscles; Level II: upper internal jugular (deep cervical) chain. To estimate the accuracy of different radiologic criteria used to detect cervical lymph node metastasis in patients with head and neck carcinoma, seven different characteristics of 2,719 lymph nodes in 71 neck dissection specimens from 55 patients were assessed. In some cases, they may indicate cancer. Lymphadenopathyis quite common, and it can be very difficult to differentiate malignant lymphadenopathy from reactive nodal enlargement. Multiple enlarged cervical lymph nodes, affecting all neck groups, with preserved oval shape and central fatty hilum, in keeping with reactive cervical lymphadenitis.
