Background: Despite the relative success of surgical
resection followed by proton, proton/photon, or
conventional radiotherapy in terms of recurrence-free
survival, chordomas are still associated with a high
rate of recurrence. To our knowledge there are only
very few reported cases of this rare tumor detected
by F-18 FDG-PET. Materials and Methods: In this case
we show the significance of F-18 FDG-PET/CT in
detection of recurrent Chordoma in a 38 year old
man with a history of the disease and a newly
detected cervical lymphatic mass. Results: The fused
PET/CT images manifested the presence of two
abnormal foci of tracer uptake corresponding to a
retroclavicular and an infrajugular Lymph node
proved to be metastases of the previous chordoma in
histopathology. Conclusion: Further employment of
F-18 FDG-PET/CT in this rare tumour type might
eventually define and establish its value in staging of
chordoma. Iran. J. Radiat. Res., 2012 10(2): 109‐110
