title: Incidental Sclerosing Pneumocytoma Detected on Bone Scintigraphy.
abstract: Nonosseous uptake in Tc-hydroxymethylene bone scintigraphy should always be evaluated for any possibility of pathological changes. We share interesting images of a 60-year-old woman initially investigated for suspected osteomyelitis of the left femur but found to have an extraosseous uptake in the right hemithorax on bone scintigraphy. Plain chest radiograph followed by contrast-enhanced CT of the thorax revealed the presence of a lung mass in the right lower lobe with no lymphadenopathy. CT-guided biopsy yielded fibrocollagenous tissue, partly lined by benign pneumocytes. The F-FDG-avid lung mass was confirmed to be sclerosing pneumocytoma postlobectomy.
