Significado clínico de la hipercaptación costal única en la gammagrafía ósea. A propósito de un osteoblastoma

Abstract

A case of a bone tumor located in the right sixth rib detected by means of the bone scan as a solitary lesion is presented. Although the chest X-ray and CT were normal, a low signal intensity on T1 images and high-intensity on T2 images were seen in the MRI. The post-surgical histological diagnosis was osteoblastoma. A review of the clinical significance of solitary rib lesions which appear with increased uptake on bone scan was performed. When a differential diagnosis is made of a solitary rib lesion that appears on a bone scan, osteoblastoma should be considered.
