The superficial anterior cervical lymph nodes that are situated adjacent to the anterior jugular vein.these nodes drain lymph from the infrahyoid region, isthmus of the thyroid gland,. These nodes lie within the retropharyngeal space, extending cranially from the upper edge of the first cervical vertebrae (massa lateralis) to the cranial edge of the body of the hyoid bone caudally (figure).

The identification and classification of cervical lymphadenopathy can be a challenging task for the general radiologist. From head and neck tumors. Patients with a wide range of clinical presentation and disease states are often referred for imaging, although evaluation and staging of head and neck cancer is the most common indication.
The American College Of Radiology (Acr) Appropriateness.
Although imaging findings can lack specificity, nodal characteristics and associated head and neck imaging findings can assist in determining the underlying cause. Select one of the two options and click 'accept'. For nearly four decades, the most commonly used classification for the cervical lymph nodes was that developed by rouvière [] in 1938.his work, and earlier works, precisely defined the anatomic location of the lymph nodes and mapped their drainage areas [2, 3].the landmarks used in those early classifications were those identified by palpation and those noted only at surgery or.
