Many pathological processes can affect lymph nodes including specific and nonspecific inflammation, further a number of benign reactive changes and primary and secondary tumour processes. Imaging and evaluation of lymph nodes as benign or potentially malignant is particularly important mainly in case of cancer staging and for patients with incidental lymphadenopathy. The work presents an overview of imaging methods used for the diagnosis of lymphadenopathy. We mention modern imaging method of contrast-enhanced
ultrasound that requires a microbubble contrast agent for evaluation of nodal perfusion. The method is supplied with pictorial documentation of ultrasound findings. Other methods are also listed – computed tomography and magnetic resonance imaging, including their limitations and currently rarely used conventional lymphography.
