Paget's disease of the thoracic rib with extension by multifocal contiguity: pathophysiologic paradox clarified by osseous SPECT / CT

Paget's disease of bone is defined by an acceleration of focused bone remodeling, bone hypertrophy and abnormal bone structure of mono, oligo or poly-ostotic distribution. The evolution of the disease is characterized by a progression of lesions in the bones already partially achieved, without extending bone to bone by contiguity. We report a case of Paget bone disease interesting the dorsal spine and extending in an atypical way to the adjoining ribs. This case illustrates an atypical radio- scintigraphy of Paget's disease with direct extension of the likely damage to bone on bone in the skeletal truncal bridge to know well. (N.C.)
