The Lymph Node Size Chart provides information about the normal and enlarged sizes of lymph nodes in different locations of the body. Lymph nodes are small, bean-shaped structures that play a crucial role in the immune system. They help filter out harmful substances from lymph fluid and produce immune cells to fight infections. This chart includes various locations such as the cervical neck , axillary armpit , inguinal groin , mesenteric abdomen , mediastinal chest , supraclavicular above the collarbone , popliteal back of the knee , and occipital base of the skull lymph nodes. For each location, the chart specifies the normal size in centimeters and indicates when a lymph node is considered enlarged if it exceeds a certain size.

Diagram of lymph node regions as used in the Lugano and previously Ann Arbor lymphoma staging systems. The above normal node sizes are based on recommendations from the Royal College of Radiologists 1 , with the following additions:. The above normal sizes are guidelines only and must be interpreted in the context of clinical suspicion and pre-test probability. Updating… Please wait. Unable to process the form.

Figure 4. Rick Hodes. Optimisation of nodal assessment by imaging Metastases are frequently found in nodes that are not enlarged by conventional criteria [ 25 ].

Key Points. Evaluation of enlarged lymph nodes with ultrasound includes assessment of size, shape, echogenicity, borders, and vascularity. Abnormal lymph nodes are markedly hypoechoic, especially the hilum, and may have irregular borders, increased cortical thickness, and increased vascularity. In patients with enlarged cervical lymph nodes, a core-needle biopsy can be safely performed at the bedside using ultrasound guidance. Increased availability of portable ultrasound with advanced technology has allowed providers to safely perform more procedures at the bedside. In particular, use of ultrasound to evaluate and guide percutaneous needle biopsies of head, neck, axillary, and inguinal lymph nodes has become more readily available. This chapter focuses on evaluation of neck lymph nodes, but the basic principles described in this chapter can be applied to evaluation of lymph nodes in other parts of the body.

Lymphocytes are the smallest white blood cells in the human body. Specifically, it is responsible for two tasks. Externally, it resists the invasion of viruses and bacteria; internally, it monitors the canceration of cells in the body. Lymph nodes are the home of lymphocytes. There are about lymph nodes in the human body, like large and small safety fortresses. Lymph nodes are one of the main lymphoid organs in the body and are located almost everywhere.

Palpation of the lymph nodes provides information about the possible presence of a malignant or inflammatory process and the localization or generalization of that process. Saul Rosenberg is a Stanford University Emeritus Professor and a luminary in the research and treatment of Hodgkin's Disease and other lymphomas. He is also a skilled bedside examiner and has wonderful tips for examining the spleen and lymph nodes. Abraham Verghese interviewed Dr. Rosenberg about his career and inspiring life story. A complete lymph node exam includes an examination of the spleen.

For example, prostate carcinoma spreads via the lymphatics in the neurovascular bundles to the obturator, presacral, hypogastric and external iliac lymph nodes. Anatomic distribution of lymph nodes in the head and neck. Anticancer Res. Br J Radiol. MR imaging must cover the entire pathway of locoregional spread of the tumour being evaluated and the sequences used depend on the anatomic region assessed. This classifies tumours according to Tumour extent, Nodal involvement and the presence or absence of Metastases. Lymph node size does not correlate with the presence of prostate cancer metastasis. Saul Rosenberg is a Stanford University Emeritus Professor and a luminary in the research and treatment of Hodgkin's Disease and other lymphomas. Uterine cervical carcinoma: evaluation of pelvic lymph node metastasis with MR imaging. Site, size and tumour involvement of resected extrapulmonary lymph nodes in lung cancer. Diffusion-weighted MR imaging The image contrast on diffusion-weighted imaging is based on differences in the mobility of water protons between tissues, and reflects tissue cellularity and the integrity of cellular membranes. Noninvasive detection of clinically occult lymph node metastases in prostate cancer. The grade and other histologic characteristics of tumours have a bearing on the likelihood of nodal metastases; e.

Key Points. Evaluation of enlarged lymph nodes with ultrasound includes assessment of size, shape, echogenicity, borders, and vascularity.

Early reports using diffusion-weighted imaging to identify malignant nodes in patients with head and neck and cervical cancers have been encouraging. The most widely used CT and MR criteria to determine if a node is benign or malignant is nodal size. The drawbacks of ultrasound include significant intra- and inter-operator variability and it is unreliable for the evaluation of deep metastatic lymph nodes. Corresponding author. Eur Urol.

The image contrast on diffusion-weighted imaging is based on differences in the mobility of water protons between tissues, and reflects tissue cellularity and the integrity of cellular membranes. In some cases, we use Artificial Intelligence for formulating the statistics.
