Mesenteric nodes are increasingly visualized as a result of multidetector volume acquisition and are most easily seen on coronal reformats.Īlthough 3 mm has previously been used as the upper limit for the short axis diameter of mesenteric lymph nodes, up to 39% of healthy normal patients have larger nodes than this. See the separate article: mediastinal lymph node enlargement. In the setting of lung cancer staging a sensitivity of 0.83 and a specificity of 0.82 are quoted for CT 5. This does not, of course, take into consideration the fact that all nodal metastases must start at microscopic size, and thus using only size criteria will miss micrometastases. In general 10 mm is considered the upper limit for normal nodes (short axis diameter) 3-5. See the separate article: cervical lymph node metastasis (radiologic criteria).

There are many (many) causes of lymph node enlargement which include: Only some nodes (including neck, axilla and groin) should ever be normally palpable and -when they are - should be soft and non-tender.
