“…It may also sometimes reveal a nidus that cannot be seen on plain X-rays, either because it is obscured by an intense sclerotic reaction or because the sclerotic bone is absent, such as with an intramedullary osteoid osteoma. MRI was compared with CT and was found to be inferior to it, and even misleading in correctly diagnosing and localizing osteoid osteoma [1,3,21].…”

Osteoid osteoma is a benign bone tumour usually occurring in young individuals (10-30 years). It presents with intense pain (typically nocturnal), which can be alleviated by salicylates. Treatment consists of surgical excision or destroying the nidus and it is curative. In the past, surgery was performed in an "open" fashion and the nidus had to be removed with a bone block. This extensive type of surgery could be associated with some rates of both failure and complication. There is growing evidence to suggest that percutaneous CT-guided removal or destruction of the nidus is a good alternative and it is indeed gaining worldwide popularity. We present a series of 18 consecutive patients with osteoid osteoma of the pelvis, femur, and tibia, treated percutaneously under CT guidance. Removal of the nidus was performed using a 4.5-mm cannulated drill and a cannulated curette of our own design. Tissue samples for histological evaluation were obtained in the same way. The mean follow-up time was 29 months. Sixteen patients were initially cured. The procedure had to be repeated in two patients and was eventually successful (primary and secondary success rates 88 and 100% respectively). The diagnosis was histologically confirmed in 14 cases out of 18 (77%). In four cases no histological confirmation of osteoid osteoma could be achieved. There were only two minor complications, one case of femoral neuropraxia and one case of skin abrasion. Percutaneous CT-guided removal seems to be efficient and safe for the treatment of osteoid osteoma. The use of a cannulated drill and a cannulated curette facilitates efficient removal of the tumour and procurement of tissue for diagnosis.

“…At MRI, a heterogeneous lesion can be observed, with hyperintense signal on T2-weighted images, and calcification within the nidus (if present) and reactive sclerosis with hypointense signal on all sequences. Bone marrow and soft tissues edema may be present, tending to simulate more aggressive lesions such as osteomyelitis and malignant neoplasms (4,8) . The treatment for osteoid osteoma is surgical; nidus ablation must be complete to avoid the lesion recidivation (9-11) .…”

“…Due to atypical presentation, diagnosis is often delayed and a high degree of suspicion is needed for early diagnosis [5]. Plain radiographs, CT, MRI and bone scan are the investigations of choice and CT is the gold standard investigation for diagnosing this lesion [6]. Surgical excision of the tumour is the treatment of choice, particularly when there is a doubt in the histology of the lesion.…”

Osteoid osteoma is a rare entity in the tarsal bones especially in children. High degree of suspicion is needed for early diagnosis and delay in diagnosis can cause significant disability. Radiofrequency ablation (RFA) is safe, minimally invasive method especially to treat juxta-articular and inaccessible lesions. Atypical Osteoid osteoma can present with clinical features similar to that monoarticular juvenile idiopathic arthritis. This case highlights the unique features of a rare entity and a successful method of treating Osteoid Osteoma of the Talus with radiofrequency ablation after procuring tissue for biopsy by a novel method.

Osteoid osteoma: MR imaging versus CT.

Abstract: CT remains the best imaging modality for diagnosis of osteoid osteoma. MR images should not be interpreted without reference to plain radiographs and CT scans if serious errors in diagnosis are to be avoided.
