FDG PET/CT revealed hypermetabolic enlarged lymph nodes in bilateral neck (largest in left supraclavicular (47 mm x 36 mm SUVmax 10), axillae (right 22 mm x 34 mm SUVmax 11.4), and mediastinum (largest right paratracheal 44 mm x 30 mm SUVmax 10) [Figure 1a-i]. There were also multiple hypermetabolic deposits in muscles of the neck, shoulders, and both pectoral regions and hypermetabolic skin lesions over the right anterolateral chest wall and sternal (SUVmax 10.5) regions [Figure 1a-i].
