유골골종(osteoid osteoma)은 특징적으로 직경 약 1cm미만의 원형 또는 타원형의 유골질제부(nidus)가 병소의 중심부에 있고, 그 주위는 반응성골질로 둘러싸여 있다. 그러므로 반응성골질 병소에서 제부의 확인은 유골골종의 진단에 매우 중요하다. 더우기 유골골종의 치료는 반드시 제부를 제거하여야 하기 때문에, 제부의 위치를 정확히 아는 것이 중요하다. 그러나, 유골골종의 제부는 단순 X-선 촬영상에서 잘 안나타나는 경우가 많아 진단에 어려움이 있다. 또한 골스캔도 유골골종의 진단에 많이 이용되고 있으나, 단순 신티그램에서 제부의 정확한 위치 파악은 어렵다. 이에 저자들은 바늘구멍조준기 골스캔을 시행하여 유골골종 제부에는 아주 진한 동위원소 집적이 보였고 주위의 반응성 골질 부위에는 제부보다 약한 동위원소 집적이 보여 특징적인 '이중 농도 집적' 소견을 얻었기에 바늘구멍조준기 골스캔이 유골골종의 진단에 매우 유용한 검사로 사료되어 보고하는 바이다.

Although Osteoid osteoma has occurred in every bone of the body, it is rarely found at the elbow and in younger children than 5 years old. In 2 years old child, diagnosis can be delayed because of nonspecific clinical, radiological features and making it difficult for the child to communicate with physician. We report a case of osteoid osteoma of the distal humeral metaphysis with intracapsular nidus and synovitis of elbow in 2 years old girl who was treated by a surgical excision.

Osteoid osteoma can occur in all parts of the skeletal system. More than half occur in lower extremity and rare in wrist. Clinically pain is almost the only symptom worse at night and which is characterized by a rapid improvement by NSAID. We report the cases of osteoid osteoma which shows the characteristic symptoms and got a good results with appropriate imaging work up and surgical treatment.

Purpose: To analyze the postoperative functional and radiographic follow-up results in patients who underwent percutaneous radiofrequency ablation therapy after the diagnosis of osteoid osteoma. Materials and Methods: Seven patients, who were clinically and radiographically diagnosed with osteoid osteoma from July 1999 to January 2001, and received percutaneous radiofrequency ablation therapy. The average follow-up period was 15.5 months(range, 8~25 months). For the diagnosis and accurate localization of the lesion, simple radiography, computed tomography and magnetic resonance imaging(MRI) were performed preoperatively. Simple radiographs and MRI were taken periodically for the follow-up studies. Results: In all 7 patients, symptoms completely disappeared within 3 days after the operation. The average period of hospitalization was 2.4 days, excluding 1 patient who needed an additional burn treatment. The average postoperative night and day pain scores were 1.8 and 1.3, respectively. The average vocational and recreational activity scores were 1 and 0.6, respectively. Conclusions: Satisfactory functional results were obtained with percutaneous radiofrequency ablation therapy for the elimination of osteoid osteoma. Compared to conventional treatment, the advantages of this therapy were short hospitalization period, no internal fixation and bone graft for preventing fracture, and no limitation of joint motion by long fixation period.

The typical radiologic findings of a small radiolucent nidus with surrounding sclerosis and night pain responding to aspirin make the diagnosis of osteoid osteoma not too difficult. We report a case of multicentric osteoid osteoma with unusual clinical and imaging features which were strongly suggestive of subacute sclerosing osteomyelitis.

Osteoid osteoma is a benign osteoblastic tumor composed of osteoid and atypical bone, with a loose, highly vascular fibrous marrow. The tumor has been reported in most of the bones of the body, but it is infrequently localized to the hand. The scaphoid is the carpal bone involved most frequently. Typically the lesions are painful and respond to aspirin. Roentgenologic finding of the central area of lucency surrounded by sclerotic bone often is diagnostic. Block excision with bone grafting is an acceptable method of treatment. We report a case of osteoid osteoma in scaphoid with a review of the literature.

We report the radio-frequency ablation technique applied on an osteoid osteoma under CT guide and review other new methods of treatment for the osteoid osteoma. An 18-year-old boy with an osteoid osteoma at the left proximal tibia, which was visible at plain film and MRI. He was treated by the percutaneous radio-frequency ablation technique under CT guide after a needle biopsy. He is free from any symptom and able to do daily activities. So, we proposed that the percutaneous radio-frequency ablation technique under CT guide is the effective and safe treatment method for an osteoid osteoma.

Purpose: To report two cases of bone tumors other than osteoid osteoma in the proximal femur and treated with percutaneous high frequency radioablation method. Cases: We reviewed two cases with intracortical chondroma and enchondroma in the femoral head retrospectively. The patient with intracortical chondroma was a thirty one year old woman and had suffered right hip pain of 1 year duration. The lesion was located in the head of right femur and treated with CT guided percutaneous high frequency radioablation after needle biopsy under general anesthesia. The symptom was gone immediately after the procedure and was discharged postop. 1 day. 15 months has passed without symptom recurrence. Second case having enchondroma, was 56 year old woman complaining of gluteal area pain for 3 months. Radiologic evaluation showed osteolytic lesion with sclerotic rim on the inferior portion of the left femoral head. She received a same therapy with CT guided radiofrequency ablation following needle biopsy. She reported dramatic pain relief after the procedure and was discharged postop. 1 day. No symptom has occurred for 3 months until now. Conclusion: We present 2 cases of bone tumor occurred in the hip joint area other than osteoid osteoma which were treated with CT guided radiofrequency ablation.
