ABSTRACT
A patient with a history of breast cancer and known lung metastases was referred for a bone scan to investigate the cause of severe neck and right shoulder pain. The bone scan showed massive uptake of the radiopharmaceutical in the soft tissue surrounding the right shoulder. A review of the patient's history indicated that the patient had undergone radiation therapy to the right upper thorax and breast area 14 months previously and an acute radiation dermatitis of the proximal right arm and should had developed. This had long since resolved. Physical examination and plain radiographs of the right shoulder and humerus failed to demonstrate any abnormality.

A patient with cystic fibrosis and a previous cholecystectomy, underwent Tc-99m mebrofenin scintigraphy to rule out hepatobiliary disease. The scan revealed multiple focal collections of radiopharmaceutical within the liver parenchyma. This unusual pattern of multiple focal parenchymal activity may be specific for patients with cystic fibrosis. This is the first time this unusual pattern has been confirmed at autopsy.

A patient complaining of headaches and bone pain at multiple sites had Tc-99m MDP scintigraphy performed for possible bone trauma after a motor vehicle accident. Bone imaging revealed a small focal increase in tracer uptake in the area of the laryngeal cartilage. There was some reluctance to place a label on this abnormality because the findings were so unusual. The initial diagnosis was a probable fracture of the laryngeal cartilage. Computed tomography of the neck also demonstrated a fracture but correctly localized it to the thyroid cartilage.
