The parotid gland is in intimate relation with the lymph nodes (seeImage.Lymph Nodes of the Head and Neck). This is the only salivary gland with 2 nodal layers, which drain into the superficial and deep cervical lymph system. Most nodes are located within the superficial lobe between the gl...

Imaging of lymph node metastases in the neck can have two major indications: (1) prognosis and assisting with choice of treatment; (2) staging and detection of clinically occult metastases in different levels of the neck. Both indications are discussed. The role and limitations of US and US-...
Background and objectives:Currently there are no recommendations for obtaining a preoperative neck ultrasound for patients with suspicious or indeterminate thyroid nodules. Because a preoperative surgical ultrasound can detect suspicious lymph nodes that could result in ultimately altering surgical management, ...
They were admitted for a high resolution neck ultrasound examination. Sixteen of 63 patients presented images suspicious for lymph node metastasis and/or for local recurrences (4 cases). Fine needle aspiration confirmed the suspicion of malignancy in 12 patients: only lymph node metastasis in 8 ...
During SLNB, local anesthesia with light sedation was administered to the patient, and a 99MTc-labelled colloid tracer was injected around the tumor, localization of sentinel lymph nodes was performed using a gamma detection system with a hand-hold probe, then the nodes were biopsied. If node ...
cervical lymph nodessurgerypathologyHigh-resolution sonography is becoming a method of choice for the detection and diagnosis of cervical lymph node metastasis in patients with papillary thyroid carcinoma (PTC). The purpose of this study is to assess the diagnostic accuracy of neck ultrasound (US) ...
Lymphatic drainage is important to understand due to the aggressive metastasis of some laryngeal cancers. Lymphatic drainage varies individually, but consistencies exist. Supraglottic structures drain lymph to the deep cervical lymph nodes, which can further subdivide into levels. Subglottic structures drain...
On ultrasound, malignant lymph nodes may be increased in size (>1–1.5 cm in greatest diameter) and may have lost their characteristic reniform shape, appearing more round in morphology. Malignant lymph nodes may show decreased internal echogenicity with loss of the echogenic fatty hilum.5 Size ...
