title: Recurrent osteoid osteoma: a case report with imaging features.
abstract: We present a case of a 14-year-old boy, who presented with pain in the left thigh region for 1 year. The pain exacerbated at night, waking up the child and was relieved by salicylates. On the basis of clinical history, conventional radiography, computerized tomography and bone scintigraphy, a diagnosis of osteoid osteoma was made. The tumor was completely excised, and there was complete remission of symptoms. Six months following surgery, the pain recurred in the same region. Conventional radiography revealed dense sclerosis at the surgical site. Three-phase skeletal scintigraphy showed a focal area of increased blood pool activity followed by intense focal uptake in delayed images, characteristic of osteoid osteoma. Computerized tomography confirmed the findings of skeletal scintigraphy.
