The involvement in the spine of eosinophilic granuloma is not common. Especially, involvement of cervical spine and posterior neural arch is quite rare. In addition, radiographic findings including magnetic resonance images of eosinophilic granuloma are manifested as vertebral body collapse, loss of pedicle and paravertebral soft mass formation; it must be differentiated with other conditions, such as malignant bone tumor, metastatic cancer or tuberculous spondylitis. We experienced three cases of eosinophilic granuloma involving posterior neural arch of C4, C7, and body of C4 respectively, which were performed surgical treatment and achieved complete healing. We report these cases with review of literatures.

Depending on the location of the lung tumor, the choice of treatment technique should be considered when treating the Cyberknife. The 4DCT images of 18 lung cancer patients were analyzed, and location error values were extracted through application program. The evaluation result was lower than the average position error only in the upper and the inner. These results suggest that the Vertebral tracking technique is effective when it is close to the pulmonary attachment or near the vertebral body, and the Synchrony technique is effective at other positions. In the future, we would like to study cyber knife treatment technique according to the position of the tumor as well as the volume of the lung and the respiratory cycle.

A combined anterolateral and posterior approach with thoracotomy has been recommended as the traditional surgical approach for the tumors of the thoracic spine. Recently, because of the morbidity associated with open thoracotomy, the thoracoscopically assisted surgical technique was introduced successfully in thoracic spinal surgery. Herein, we report a combined surgical technique for giant cell tumor of the thoracic spine (T10) consisting of bilateral thoracoscopic anterior release of the spine followed by a posterior on bloc spondylectomy and reconstruction by orthopedic surgeons. The thoracoscopic spinal surgery is safe and effective alternative for other open thoracotomic procedures in the approach to the anterior thoracic spine, avoiding the disadvantage inherent to thoracotomy.

Purpose: Giant cell tumor of the spine is very rare, and the treatment is very difficult. However, surgical techniques and diagnostic modalities are developed, and postoperative functional results are improved. To evaluate the efficacy of total spondylectomy for giant cell tumor of the spine, the clinical results of the surgical treatments for the giant cell tumor of the spine with intralesional curettage or total spondylectomy were evaluated. Materials and Methods: From April 1987 to March 2006, 10 patients who were underwent surgical treatments using total spondylectomy or intralesional curettage were studied. There were 3 men and 7 women. The mean age of the patients was 32 years (range, 25~44 years). The mean duration of follow-up was 8 years (range, 3~15 years). Locations of the tumor were 2 cervical spines, 4 thoracic spines, 2 lumbar spines and 2 sacrum. Initial main symptom of 10 patients was pain, and 7 patients had neurologic impairments too. Four patients were treated with total spodylectomy using anterior and posterior combined approach, 1 patient was treated with total sacrectomy using posterior approach only, and 5 patients were treated with intralesional curettage using anterior approach. Results: Nine patients improved pain and neurologic impairments. Local recurrences developed in 4(40%) patients (2 cervical spines, 1 thoracic spine, 1 sacrum). While a local recurrence developed from 5 total spondylectomy, 3 local recurrences developed from 5 intralesional curettage. Conclusion: Local recurrence rate after surgical treatment with intralesional curettage for the giant cell tumor of the spine was very high. Total spondylectomy using anterior and posterior approach is advisable to prevent the local recurrence after surgical treatment.

The operative case of transmanubrial osteomuscular sparing approach for the tumor involving thoracic inlet is reported. A 69-year-old man visited the hospital due to right upper extremity weakness. Chest roentgenogram showed bronchiectasis, chronic pulmonary tuberculosis, and fungal ball in right upper lobe. On computed tomogram, tumor was located in epidural space of the 6th, the 7th cervical, and the 1st thoracic spine and extended to the apex of the right thorax. A neurosurgeon performed laminectomy and removed the tumor located in the spinal canal. A thoracic surgeon performed a transmanubrial osteomuscular sparing approach and removed the tumor involving thoracic inlet. The tumor was diagnosed as hemangiopericytoma. The patient recovered without complication.

Metastatic bone tumor is the most common bone tumor and 32.5% of all primary malignant tumors are eventually metastasize to bone. Metastatic bone tumor has been more frequently encountered disease in the orthopedic fields due to the greater longevity of life of the patients with primary visceral cancers by major advances in early detection, diagnosis, and surgical/radiotherapeutic/chemotherapeutic treatment of primary and metastatic lesions. Therefore, the epidemiologic data about the incidences and the patterns of bone metastasis is important. We reviewed 417 patients who were diagnosed and treated for metastatic bone tumor at Kosin University Medical Center from 1985 to 1993 to analyse the primary lesion, age and sex distributions, location of bone metastasis, patterns of metastasis according to the primary. The results were as follows : 1. The common origin of bone metastasis were lung(29.5%), stomach(15.3%), breast(11.3%), unknown(7.7%), cervix(5.3%), liver(4.8%) in order of frequency. 2. There were 251 men and 166 women and their mean age was 54.8 years and the peak age incidence was in 6th decades. Most cases(85.3%) were occured beyond 5th decades. 3. The preferred sites of metastatic deposits were spine(64.0%), pelvis(40.5%), rib(38.8%), femur(36.7%), skull(21.1%), humerus(13.9%), scapula(13.0%) in order of frequency. In the spine, thoracic(42.1%), lumbar(39.1%), cervical(13.2%), sacral(5.6%) vertebrae were involved in order of frequency. 4. Multiple bone metastases were more common(73.1%) than single metastasis(26.9%). 5. In the lung cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, pelvis, femur. 6. In the stomach cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, femur, pelvis. 7. In the breast cancer, the peak age incidence was 5th decades, and the preferred sites of bone metastasis were spine, rib, pelvis. 8. In the bone metastasis with unknown primary site, the peak age incidence was 7th decades, the preferred sites of bone metastasis were spine, femur, pelvis, and the common histologic types were adenocarcinoma and squamous cell carcinoma.

Thyroid cancer is known as its relatively high cure rate after surgical treatment and spinal metastasis of thyroid cancer is extremely rare as the prevalence is only 2-13%. Spinal metastasis is usually asymptomatic and discovered incidentally in most cases. A 66-year-old man was diagnosed as thyroid papillary cancer with spinal metastasis. We treated the patient by surgery, adjuvant radiotheraphy and radioactive iodine therapy. C6 corpectomy was followed for the residual spinal metastasis by the department of neurosurgery. The patient had no functional complication by the surgical process. At 24 months after surgery, there was no sign of recurrence and the patient led social life without any discomfort. We present this case with a review of the related literatures.

A 45 year old man was admitted for further examination of an abnormal shadow of the right posterior mediastinum. The patient suffered from dysesthesia in the right thoracic wall of dermatome T7. CT scan and MRI revealed that two separate tumors had developed in the right paravertebral area linked to the vertebral canal via an intervertebral foramina. One-stage removal of the tumors were performed safely through the right posterolateral thoracotomy following the resection of the rib head and vertebral pedicle. The tumors were confirmed as histologically neurilemomas. The postoperative course was uneventful.
