RESUMO
A 49-year-old male patient with a prior history of poor compliance with medical appointments was referred for an 18F-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) for the staging of a rectal squamous cell carcinoma. The PET/CT showed unilateral diffuse skeletal muscle 18F-FDG uptake as well as bilateral salivary gland uptake artifacts, suggestive of non-compliance with patient preparation instructions. The PET/CT nurse noted that during the 18F-FDG uptake phase, the patient appeared intoxicated, and she found two beer cans hidden in the waste disposal beside his chair just prior to imaging. The patient only admitted to eating a cookie approximately 30 minutes after the injection of 18F-FDG PET/CT and denied consuming alcohol during the uptake phase. We present the imaging findings of non-compliance with patient instructions during the uptake phase of 18F-FDG.
RESUMO
A 49-year-old woman with known Klippel-Feil syndrome had a CT scan for staging of stage IIIA invasive carcinoma of the left breast. She was found to have cervicothoracic spinal dysraphism with diastematomyelia. An F-NaF bone PET done as part of the metastatic workup showed the characteristic sagittal bone spur, and MRI demonstrated a complete split of the cervical and upper thoracic spinal cord, previously unknown to the patient.
