Osteoid osteoma: an unusual cause of articular pain.

Abstract

Twenty-five patients who had histologically proved osteoid osteoma and whose major symptom was joint pain were studied. Retrospective study of clinical data and radiographs revealed that almost all of the lesions were located near the painful joint and that there had been significant delay in determination of the correct diagnosis. The delay was related to the nonspecificity of symptoms, the latency between the onset of symptoms and the appearance of the lesion on radiologic study, and the evaluation sequence used in some patients. The relative effectiveness of various diagnostic modalities is discussed. Radionuclide bone scanning, plain radiography, and guided tomography are the most useful diagnostic studies.

Arthroscopic Excision of Acetabular Osteoid Osteoma: Computer Tomography–Guided Approach

“…6 The radiolucent nidus is not reliably detectable if below 3 mm in size and thus is often overlooked. 15 MRI is generally accepted as the modality of choice for bone tumor exploration. 16,17 The signal intensity of MRI is dependent on the age, size, vascularity, and amount of calcification present.…”

Radiofrequency Ablation of Intra-articular Osteoid Osteoma of the Hip

“…4 The nidus will commonly not be identified on radiographs and scintigraphy may not show classical features. Intra-articular cancellous or subperiosteal osteoid osteoma must be differentiated from inflammatory, septic or tuberculous arthritis, 1,42 Legg-Calvé-Perthes disease, 43 Brodie's abscess 44 and intracortical chondroblastoma. 45 Intravenous gadolinium may enable further diagnostic refinement when subacute osteomyelitis is a possible differential diagnosis.…”

Intracapsular osteoid osteoma of the proximal femur: findings on plain film and CT.

“…Therefore, osteoid osteoma should be considered early in the workup of the patient with symptoms of hip pain, limp, or pain referred to the knee [3].…”

“…Sclerosis may be lacking [4], and the intracapsular periosteum is less likely to produce new bone than the extracapsular periosteum [3]. another institution and was of good quality, but lacked pinhole views.…”

“…A radiolucent nidus (with or without a central ossified focus) may be seen [1]. When located in a portion of the bone that is within the capsule of a joint, an osteoid osteoma may present with clinical findings that are more indicative of an inflammatory synovitis and with atypical radiologic findings such as lack of both sclerosis and periosteal reaction [2][3][4]. Chronic changes of bone remodeling, such as widening and foreshortening of the femoral neck and reduction in height of the capital femoral epiphysis, also can be seen if the diagnosis is delayed for more than 3 months [4].…”
