The decision of proper time for operation on ruptured aneurysm is a very important tactic of treatment, because of the following major complications after subarachnoid hemorrhage. Recently it is widely accepted opinion that the ruptured aneurysm should receive an early operation for lower mortality and morbidity by preventing possible complications after subarachnoid hemorrhage such as rebleeding, symptomatic vasospasm and even hydrocephalus. Since 1985, we applied early to emergency surgery to the clinically deteriorating or non improving patients after aneurysm rupture and delayed surgery to the ameliorating patients who were placed under close observation. The early to emergency surgery on poor risk patient was performed within 48 hours after recent subarachnoid hemorrhage and delayed surgery was done after 2 weeks. Of the selective 95 poor-condition patients admitted to Kyungpook National University Hospital over the past 4 years from 1984, 60 got early surgeries and 35 delayed surgeries. Among the 60 patients in the early group, 22 patients with considerable intracranial hemorrhage were exempted from this comparative study. A few cases of vertebrobasilar aneurysms were not included in this paper for a little value in significance. In this prospective study, we evaluated the results of early and delayed surgeries of poor risk patients through clinical analyses and comparison, and we could gain better results from early surgeries.

Primary intracranial epidermoid carcinoma is an extremly rare sequela of epidermoid cysts. The authors had experienced a case of primary intracranial epidermoid carcinoma in the right cerebellopontine angle. Here, we report clinical, radiological, and histopathological features of this neoplasm with review of literatures.

Intramedullary clear cell meningioma(CCM), which is more aggressive than other variants of meningioma, is extremely rare. To date, only one case has been documented in spinal tumors. We report the first case of an intramedullary CCM originating in the spinal cord at the thoracic region.

Merkel cell carcinoma is a skin disease that rarely involves the spine. The common presentation of spinal involvement is quite confusing and may be easily misdiagnosed. However, once it spreads, the disease progresses rapidly, with an extremely poor outcome. We report on the case of a 30-year-old male with cervical spinal metastasis of Merkel cell carcinoma causing quadriparesis.

By carefully examining the above paper, we found that there are many same materials, expressions, and objects between this paper and a previously published paper on another journal (Park SH, Hwang SK, Park Ym: Intramedullary clear cell meningioma, Acta Neurochir (Wien) 148:463-466, 2006). Under these circumstances, the editorial committee concluded to retract this paper as soon as possible. We deeply apologize to the readers for any inconvenience caused by this retraction.

Although little attention has been paid to the less common rheumatoid involvement of the thoracic and lumbar regions, some studies have shown that rheumatoid synovitis with erosive changes can develop in these diarthrodial joints. We report a patient with seropositive rheumatoid arthritis (RA) involving the thoracic and lumbar vertebra with a collapse of the T12 vertebra, who was treated with percutaneous vertebroplasty. In this case of a painful pathological fracture due to RA, percutaneous vertebroplasty was found to be helpful in eliminating the pain. The paper presents the histological evidence, the pathogenesis and treatment of the thoracolumbar lesions affected by RA with a review of the relevant literature.
