The role of conventional radiography and CT in the assessment of initial thoracic and abdominal relapse in stage I-III Hodgkin's disease has been analysed in 43 patients. Lymph node involvement was seen in all patients, extranodal involvement in fifteen. The presence of thoracic relapse had been detected essentially by chest X-ray, but CT proved to be useful for definition of the topographic-anatomic extent of tumour manifestation. In the abdomen the presence and extent of any relapsing disease had been demonstrated mainly by CT. Additional lymphangiography was necessary in only one patient.
