Primary mediastinal seminoma with 67Gallium total body scan: a case report

We describe a case in which radionuclide scanning was used for staging and assessing treatment of a germinal neoplasm. Primary mediastinal seminoma is an ectopic manifestation of the not infrequent germinoma. Controversy surrounds the histogenesis of this tumor. Management may include surgery, radiation therapy, chemotherapy or any combination of these. Because of the rather marked radiosensitivity of the tumor the prognosis generally is favorable. The radio-gallium scan was helpful in guiding and following treatment.
