RESUMO
In two women with Hodgkin's disease, 36 and 34 years of age, the PET-scan showed increased FDG-uptake in regions where the CT-scan did not reveal any abnormalities. Integration of the PET-CT images visualised bone marrow localisations in both patients. One patient underwent a CT-guided bone biopsy that confirmed this localisation. In both cases, the results of the integrated PET-CT images altered the therapy that would have been given on the basis ofthe standard staging technique. Both patients underwent radiotherapy. After 6 months, one patient had no visible lesions. The other patient died due to progression ofthe disease. Integrated PET-CT images can play an important role, not only in the precise classification and staging of lymphoma but also at the start of therapy, as an initial scan, in the evaluation of the response to treatment, and in the early detection of recurrence.
