“…1). At least one water-sensitive pulse sequence should be included to visualize the reactive edema surrounding the lesion, which can be marked especially in younger patients [7]. Consideration of the presence of an osteoid osteoma should be made, especially in the setting of undefined bone marrow edema pattern in a young patient.…”

“…Prostaglandin-induced peritumoral abnormalities associated with OO of the femoral neck and trochanters are: (1) synovitis of the hip joint, (2) bone marrow edema and (3) juxtacortical soft tissue edema. MR imaging is the most sensitive diagnostic tool in detecting peritumoral soft tissue abnormalities induced by prostaglandins [8,9,[12][13][14]29].…”

Magnetic resonance imaging findings of osteoid osteoma of the proximal femur

et al. 2004

Osteoid osteoma (OO) is a benign bone tumor whose main radiological finding is nidus. OO of the proximal femur can also result in non-specific findings such as hip joint effusion, perinidal bone marrow edema and soft tissue mass. Since the nidus may be difficult to identify with MR, these non-specific findings can lead to erroneous diagnosis. Therefore, MR imaging technique should be optimized in order to identify nidus. Since MR imaging has assumed increasing importance in the evaluation of disorders of the hip, radiologists must be aware of the spectrum of findings of OO of the proximal femur. The aim of this pictorial review is to show the MR imaging findings of intra-articular and extra-articular OO of the proximal femur.

“…Prompt diagnosis is important to reduce the duration of symptoms and the risk of structural spinal deformity. Magnetic resonance imaging (MRI) features of appendicular OO are well described in the literature [4,5]. We describe the characteristic imaging features of spinal OO in 13 cases and underline the importance of considering this diagnosis in patients referred for MRI with vague symptoms of back pain in whom OO is unsuspected.…”

A retrospective evaluation of the imaging of 13 patients with a diagnosis of osteoid osteoma (OO) of the spine was undertaken. Available imaging included radiographs (n=10), computed tomography (CT) (n=13), bone scintigraphy (n=5) and magnetic resonance imaging (MRI) (n=13). MRI features evaluated were pattern of neural arch and vertebral body oedema and the presence of an identifiable nidus. MRI features were correlated with other available imaging. There were seven males and six females with an age range of 8-59 years. On radiographs, scoliosis was present in ten and a sclerotic pedicle in nine patients. Focal increased uptake on bone scintigraphy consistent with OO was seen in all five patients where scintigraphy was available. On CT, a nidus was identified in all patients and reactive sclerosis was seen in 12. MRI demonstrated the nidus in eight patients and unilateral neural arch oedema with anterior extension to involve the ipsilateral posterolateral vertebral body in 11. When MRI is performed in the evaluation of back pain, the presence of unilateral neural arch oedema extending to involve the posterolateral vertebral body raises the possibility of spinal OO and should prompt CT to confirm the presence of a nidus.

Peritumoral edema in osteoid osteoma on magnetic resonance imaging

Abstract: Osteoid osteomas in younger patients tend to be associated with more extensive peritumoral edema.
