We describe the positron emission tomography-computed tomography (PET-CT) findings of a patient who presented to the emergency room with chest pain and palpitations and underwent a radical cystectomy 6 months earlier because of a squamous cell carcinoma of the bladder (SCCB). Cardiac catheterization ruled out coronary artery occlusion, but PET-CT showed multiple F-18-fluorodeoxyglucose-avid lesions involving multiple skeletal muscles and the heart, consistent with metastases. A CT-guided biopsy of 1 skeletal muscle lesion confirmed a metastasis with the same pathologic features as the SCCB. To our knowledge, this is the first reported case of an SCCB with metastases to multiple skeletal muscles and myocardium detected with PET-CT.
