The impact of 18F-FDG PET-CT scanning for staging and management of Merkel cell carcinoma: Results from Westmead Hospital, Sydney, Australia Rebecca Concannon, B Med (Hons), FRACP, George S.

Fig 1 A and B, This 66-year-old Caucasian woman presented with a left axillary nodal mass (arrowhead), found to be Merkel cell carcinoma. No obvious primary was detected. PET-CT demonstrated a 5.5cm soft tissue metastasis with intense FDG uptake (SUV max 12) in the right posterior chest wall (arrow). C, Given the patient's obesity and lack of overlying skin changes, this was missed on initial clinical assessment. The patient's disease was upstaged from III to IV, and radiotherapy field and treatment intent were modified.

Fig 2 This 81-year-old Caucasian man underwent PET-CT for suspected relapse. He had been given radiotherapy to the primary site (nose) and presented with a lump on the left side of the neck, thought to be a nodal metastasis. It was planned to administer hemi-neck radiotherapy. PET-CT demonstrated uptake in this node, but also in a contralateral cervical lymph node (arrows), which was biopsy proven to represent metastatic disease. Therefore radiotherapy was delivered to both sides of the neck after bilateral lymph node dissection.
