title: Thoracic CT-scanning follow-up of residual mediastinal masses after treatment of Hodgkin's disease.
abstract: Sequential thoracic CT-scanning was performed for 14 patients presenting with residual mediastinal masses on chest X-ray after treatment of stage I and II Hodgkin's disease (HD). Eleven patients initially presented with bulky mediastinal involvement. No mediastinal biopsy was performed. No local recurrence was detected at a 48 month median follow-up. Early evaluation by CT-scanning showed cystic degeneration in three cases. Sequential CT-scans on longer follow-up demonstrated continuous regression of residual masses in six cases and no or limited volume reduction in six other cases. In two patients, part of the residual mass remained stable and the other part showed reduction in size. In addition, late calcifications developed in four cases. The results of sequential CT-scanning suggest that residual mediastinal masses do not generally represent active disease. Hence additional, potentially toxic, therapy can be avoided.
