A 22-year-old woman with acute lymphoblastic leukemia underwent FDG PET/CT to evaluate possible extramedullary disease. The patient experienced severe nausea and vomiting due to ongoing chemotherapy. The image demonstrated increased FDG uptake in multiple muscle groups, including intercostal, bilateral external oblique, internal oblique, transverse abdominal muscles, and psoas major. One week after the patient stopped vomiting, a repeated PET/CT showed much less muscle uptake.
