[en] Very few papers have assessed Bone scan (BS) in patients with fibromyalgia syndrome (FS) The aim of this study is to assess BS value in patients with FS trying to find a possible BS pattern to help in the diagnose of this pathology, as happens in other rheumatic pathologies, helping also in the differential diagnose. 19 women (age 24-69 years) have been studied. 14 of them had a clinical diagnosis of FS and 5 clinical suspicion. All were performed a great number of diagnostic tests: laboratory blood tests, X-rays, electrocardiography, electro encephalography, electromyography, ultrasonography, computerized tomography, magnetic resonance imaging and BS. All BS showed abnormal polyarticular hyperuptake foci with variable degrees with a diffuse or punctual location. Blood pool scintigraphies were negative despite clinical examination was positive. There was no relationship between the location and intensity of hyper uptake foci and clinical existence of pain. We think that patients with FS could present a variable poly articular scintigraphic pattern in location and hyper uptake foci degree (Au)
