title: The usefulness of the scan with 67Ga-citrate in the multicentric reticulohistiocytosis.
abstract: Multicentric reticulohistiocytosis is a rare systemic disease of unknown etiology. It is characterized by erosive arthritis and skin lesions. Diagnosis and treatment should be performed early to avoid sequelaes. We report the case of a 67-year-old man diagnosed with multicentric reticulohistiocytosis and left hip arthorplasty. The patient consulted for local pain in his left leg. Final diagnosis was left prosthetic dislocation. During admission, a bone scintigraphy with (99m)Tc-HDP and scintigraphy with (67)Ga-citrate was performed, showing no evidence of inflammatory activity in pelvis that contraindicating surgery. Besides it showed bilateral uptake in soft tissue of large joints compatible with persistent inflammatory activity secondary to multicentric reticulohistiocytosis. In this case scintigraphy with (67)Ga-citrate, is a useful tool to assess the recovery and extent of disease.
