BACKGROUND Osteoid osteoma is a primary benign bone lesion, which constitutes about 10% of all primary benign bone tumors and 3% of all primary bone tumors. The spine is involved in 10% of the cases, and the lumbar spine is the most commonly affected whereas the tumor is rarely seen in the cervical spine. With regard to the osteoid osteoma being located at the odontoid process of the axis, limi...

INTRODUCTION Osteoid osteoma is a painful benign tumour, which is commonly treated by radiofrequency ablation (RFA). The goal of this study is to assess the value of contrast-enhanced magnetic resonance imaging (MRI) for predicting clinical success after RFA of osteoid osteoma. METHODS Twenty consecutive patients (14 male, 6 female; mean age 23.3 ± 13.4 years) suffering from osteoid osteoma u...

Osteoid osteoma is a benign bone tumor that rarely affects the carpal bones. Because of its nonspecific presentation in the wrist, it remains a diagnostic challenge. We report an unusual case of osteoid osteoma in the capitate where the diagnosis was delayed and the presentation was that of an aggressive natured lesion with considerable functional incapacitation. Diagnosis was made by computed ...

BACKGROUND The most important symptom in patients with osteoid osteoma and osteoblastoma is a resistant localized neck pain and stiffness in the spine. OBJECTIVE To evaluate and analyze 6 cases of osteoid osteoma and osteoblastoma of the cervical spine that were surgically treated over a 7-year period and to emphasize the unusual persistent neck pain associated with osteoid osteoma and osteob...

A minority of osteoid osteomas are found to be juxta-articular and within the small bones of the wrist. We present a 30-year-old man diagnosed with an osteoid osteoma of the lunate bone, presenting with 3 years of left wrist pain, swelling and reduced range of motion. Given the patient's background and laboratory testing, consideration was given to both inflammatory and infectious causes and th...

Osteoid osteoma in the base of the coracoid process of the scapula is very rare and diagnosis and treatment often is delayed. A lesion in this atypical location may seem surgically unreachable. This report is of a case of osteoid osteoma in the base of coracoid process in a 14-year-old female. The lesion had been diagnosed as a nontumorous condition and overlooked for four years. Computed tomog...

The case of a relatively frequent benign osteoblastic tumour, osteoid osteoma at an atypical site is presented. It was in a 20 year old man who attended the outpatient department of Aga Khan University Hospital, Karachi with pain in left groin since last 6 months which often occurred at night and was relieved by taking NSAIDs. X-ray failed to reveal the cause. CT scan showed central radiolucent...

BACKGROUND Osteoid osteoma is a painful benign osteogenic tumour for which the treatment objective is surgical resection of the nidus. The acetabular fossa is an uncommon site of involvement where surgical access can prove challenging. MATERIALS AND METHODS We report a case-series composed of five patients with osteoid osteoma of the acetabular fossa treated with percutaneous bone resection a...

INTRODUCTION Osteomas are asymptomatic and rare slow growing bony tumors in temporal bone, and should be taken into account in differential diagnosis of the osteolytic solitary skull lesions. Sometimes is associated with pain and functional loss. Only a few cases have been reported. CASE REPORT We describe a case of an osteoid osteoma of the temporal bone (mastoid) in a 31-year-old woman pres...

A case of cervical osteoid osteoma is reported, with a brief account of the diagnosis and treatment of these lesions. Cervical osteoid osteoma is rare but its pattern of presentation varies little and it should therefore be possible to suspect it on clinical grounds alone. Bone scanning is now regarded as more efficient than radiography in identifying the lesion but X-ray tomography will normal...
