It would be intermittent at first and later become continuous, making it difficult for him to walk, and swelling was observed in that area. The treatment consisted of nonsteroidal anti-inflammatory drugs (NSAID), initially ibuprofen, which was replaced by diclofenac, but there was no improvement. He had no history of injury, fever or constitutional symptoms, or manifestations affecting any other peripheral or axial joint or enthesitis. He had been diagnosed with guttate psoriasis at the age of 10 years, with occasional episodes until he was 13, and was treated with topical glucocorticoids; however, he had no family history of psoriasis, psoriatic arthritis, ankylosing spondylitis or inflammatory bowel disease. Physical examination revealed muscle atrophy in distal thigh and swelling in right infrapatellar region, which was warm, and he had a limitation in last few degrees of flexion, but with no signs of joint effusion. The results of laboratory tests, including biochemical analyses, complete blood count and acute-phase reactants (erythrocyte sedimentation rate 6<span class="elsevierStyleHsp" style=""></span>mm/h, C-reactive protein 2.31<span class="elsevierStyleHsp" style=""></span>mg/dL) were normal. Human leukocyte antigen (HLA) typing revealed the presence of Cw6, DR4 and DQ8 haplotypes, but not B27, and the patient was negative for rheumatoid factor and antinuclear antibodies. Plain radiography of the knees showed a sclerotic area in the upper third of right tibia (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>A and B), which, according to computed tomography (CT), corresponded to an osteolytic lesion measuring 5<span class="elsevierStyleHsp" style=""></span>mm in diameter in anterior tibial tuberosity, with a “nidus” formed by an ossified matrix, compatible with OO (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>B and C), with extensive sclerosis of the medullary bone and a solid periosteal reaction in the adjacent cortical bone. Magnetic resonance revealed intense contrast uptake in and around the lesion, as well as in the surrounding bone edema and the Hoffa fat pad (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>C and D). Bone scintigraphy disclosed hyperemia and a focal increase in the osteogenic response in the proximal epiphysis of right tibia, with no other significant changes. The patient underwent CT-guided radiofrequency ablation, and the pain disappeared a few days after the procedure, and he recovered complete mobility 1 month later, although he had mild persistent muscle atrophy.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><p id="par0015" class="elsevierStylePara elsevierViewall">Osteoid osteoma is a relatively common, benign bone neoplasm that constitutes between 10% and 12% of benign bone tumors.
