FDC-PET image of a highly metabolically active malignant melanoma mass involving the oesophagus with no other sites of disease
The yield of whole-body CT scanning in discovering distant
metastases of primary cutaneous melanoma in asymptomatic
individuals is low.7 While fluorodeoxyglucose positron emission
tomography (FDG-PET) is of proven value in the detection of
metastases in these patients (changing planned clinical management
in up to 22% of patients) its utility in oesophageal melanoma is
unclear.8 FDG-PET imaging of our patient (Fig. 1) demonstrated
no evidence of adjacent nodal disease, however it is accepted that
micrometastases and lesions <10 mm may not be detected.
