[Rare manifestations of axial skeleton gouty arthropathy].

Clinical manifestations of gouty arthropathy are usually acute inflammatory arthritis, bursitis and accumulation of urate crystals in the form of tophi. Manifestations on the axial skeleton are also known and have been described but occur infrequently and for this reason play a subordinate role in the awareness of rheumatologists. With dual energy computed tomography (CT) gout tophi can be detected even in unusual regions or regions that are difficult to access for puncturing. We describe two rare cases of gouty arthropathy of the axial skeleton in a 76-year-old male patient with spinal involvement and in a 53-year-old female patient with involvement of the sacroiliac joint. In both cases the diagnosis was achieved with dual energy CT.
