title: Intraarticular osteoid osteoma: sonographic findings in three patients with radiographic, CT, and MR imaging correlation.
abstract: OBJECTIVE
  Intraarticular osteoid osteoma often has subtle radiographic findings and nonspecific clinical features; further diagnostic workup of unexplained joint pain may involve musculoskeletal sonography. We describe the sonographic features of intraarticular osteoid osteoma in three consecutive patients with radiographic, CT, and MR imaging correlation.
  
  
  CONCLUSIONS
  The sonographic findings of painful cortical irregularity and focal synovitis should raise the possibility of intraarticular osteoid osteoma, prompting the search for characteristic findings on correlative imaging studies.
