title: A case of paranasal sinuses osteoma detected on bone SPECT/CT.
abstract: We present a 51-year-old woman with a history of colectomy for colon cancer who was referred to our department for bone assessment. Planar image revealed a focus of increased uptake of Tc-99m methylene diphosphonate in the nose root. According to the images of SPECT combined with low-dose CT, the abnormal radiotracer uptake at the site of left frontal sinus was considered to be osteoma. We conclude that SPECT/CT provides an accurate evaluation of the localization of the lesions and supplies anatomic information that can be valuable for diagnosis of nonmalignant bone diseases.
