Positive 57Co-bleomycin scintigraphy in silent mediastinal metastases of malignant melanoma

Abstract

A case with an intense accumulation of 57Co-bleomycin in lymph node metastases of malignant melanoma in the mediastinum as a casual finding is reported. The patient had undergone a 57Co-bleomycin scintigraphy because of a peripheral lesion on the chest X-ray, in which a pathological diagnosis was impossible to obtain. This lesion showed no uptake of the radiopharmaceutical.
