Abstract
A 46-year-old man with early gastric cancer at
the gastric antrum underwent an F-18 fluorodeoxyglucose
(FDG) positron emission tomography (PET)-computer
tomography (CT) scan for staging. No definite
abnormal FDG uptake of the stomach was shown.
Incidentally, variable FDG uptake at the bilateral serratus
muscles, abdominal muscles and muscles of both thighs
(Fig. 1) was observed. He had no significant past medical
history except recently diagnosed stomach cancer. On
personal interview, he described having had sexual
activity the night before the F-18 FDG PET/CT scan,
although he was aware of needing to avoid physical
activity before a PET scan. The F-18 FDG PET/CT scan
was done at 2:00 p.m. Therefore, the hypermetabolism of
individual skeletal muscles following sexual activity
lasted over 12 h. This case illustrates the hypermetabolism
of skeletal muscles following sexual activity as a normal
variation.
