Lymphographic classification of malignant lymphoma.

In an attempt to raise the diagnostic accuracy of lymphography in malignant lymphoma, especially in early stages, the disease were radiographically classified into 3 groups such as atypical, typical and advanced group mainly based on the lymphographic findings. The findings showed characteristic features corresponding to the stages of the disease. Atypical group showed the following findings: small filling defects, increased number of lymph node and visualization of the marginal sinus. The findings were regarded as those of early stages of malignant lymphoma.
