Diagnostic radiology of extranodal lymphomas
Summary. Positron emission tomography/computed tomography and contrast computed tomography are standard methods for diagnosing lymphomas, according to the Lugano classification (2014). Their integrated use is necessary in the initial diagnosis of lymphomas and in control studies at the stages of specific treatment. Magnetic resonance imaging is the standard method only for extranodal lymphoma with central nervous system damage. In this paper, aspects of CT-diagnostics of primary extranodal gastric lymphoma are defined, and the features of computer images that allow the diagnostician to suspect extranodal lymphoma are specified. Also the nuances of differential diagnosis of primary extranodal lymphoma of the stomach with other similar malignant processes are considered.
