Abstract

A 69-year-old man with a history of COPD and small-cell lung cancer was referred for F-18 fluoro-2-deoxy-glucose (FDG) whole-body positron emission tomography (PET) with computed tomography (CT) fusion. The patient had chronic shortness of breath by history, and was noted to have heavy breathing with cough at the time of tracer injection. The PET scan shows marked F-18 FDG uptake in virtually all accessory muscles of inspiration, including the sternocleidomastoids, scalenes, intercostals, diaphragm, crura of diaphragm, and some abdominal wall muscles. In addition, these accessory muscles are noted to be hypertrophied on CT, which likely contributed to the degree of hypermetabolic activity seen on PET.
