We report a case of intracranial dissemination developing approximately 4 months after partial removal of a spinal cord anplastic astrocytoma in a 22-year-old male. He presented with paraplegia on initial admission at a local hospital. Spinal magnetic resonance (MR) images disclosed multiple intramedullary lesions at the T3-11. The tumor was partially removed. The final histologic diagnosis was anaplastic astrocytoma. Four months after the operation, he was admitted with the symptoms of headache and deterioration of consciousness. MR images showed enhanced lesions in the anterior horn of the left lateral ventricle, and septum pellucidum. He underwent computed tomography-guided stereotactic biopsy and histological appearance was consistent with anaplastic astrocytoma. The clinical course indicates that the tumor originated in the spinal cord and extended into the subarachnoid space, first the spinal canal and later intracranial.

Objective : The incidence of leptomeningeal dissemination from malignant glioma is rare, so the clinical features of this are not well documented yet We attempted to determine the clinical features of leptomeningeal dissemination from malignant gliomas. Methods : We retrospectively analyzed 11 cases of leptomeningeal dissemination of malignant glioma, who were treated at our institution between 2006 and 2009. We investigated the clinical features of these patients by considering the following factors : tumor locations, the events of ventricular opening during surgery and the cerebrospinal fluid (CSF) profiles, including the cytology. Results : The group was composed of 9 males and 2 females. The histological diagnosis of their initial intracranial tumors were 4 primary glioblastoma, 3 anaplastic astrocytoma, 1 anaplastic oligoastrocytoma, 2 ganglioglioma and 1 pleomorphic xanthoastrocyotma with anaplastic features. The mean age of the patients at the time of the initial presentation was $42.8{\pm}10.3$ years. The mean time between surgery and the diagnosis of spinal dissemination was $12.3{\pm}7.9$ (3-28) months. The mean overall survival after dissemination was $2.7{\pm}1.3$ months. All our patients revealed a history of surgical opening of the ventricles. Elevated protein in the CSF was reported for eight patients who had their CSF profiles checked. Conclusion : We propose that in the malignant gliomas, the surgical opening of ventricles can cause the spinal leptomeningeal dissemination and the elevated protein content of CSF may be a candidate marker of leptomeningeal dissemination.

Objective : The purposes of this article are to present 5 cases of intracranial meningioma with leptomeningeal dissemination (LD) and investigate the characteristics of this disease. Methods : We present a retrospective case series of 5 females at our institutions (age ranged 21-72 years, mean 54.6 years) diagnosed with LD of an intracranial meningioma after surgery between 1998 and 2013. A database search revealed 45 cases with LD of meningioma in the English literature. Characteristic features were analyzed and compared. Results : The incidence rate at our institutions of LD of meningioma was 0.9% (5/534). World Health Organization (WHO) grade was distributed as follows: I : 2, II : 2, and III : 1. Time to LD ranged from 2.5 months to 6.9 years; the patient with WHO grade III had the shortest interval to LD. The patient with an intraventricular meningioma (WHO grade II) had the second shortest interval to LD (1.7 years), and simultaneously revealed both LD and extraneuronal metastases. Four of 5 patients showed a disease progression, with the survival ranging from 1 month to 3.8 years after LD. Based on the literature, the initial tumor was an intraventricular meningioma in 9 patients, and their time to LD was shorter on average (mean 1.9 years). Histologically, 26 of 45 (58%) were initially diagnosed with a WHO grade II or III meningioma, and 6 of 19 patients (32%) with WHO grade I revealed malignant transformation. Conclusion : This study shows that intraventricular location and histologically aggressive features seem to increase the chance of LD of meningioma.

There are several mechanisms for the dissemination of lipid material from a mature teratoma into the subarachnoid space or ventricles, including iatrogenic or traumatic rupture, but spontaneous rupture of a mature teratoma is rare We report the spontaneous rupture of a spinal mature teratoma into the subarachnoid space and ventricles. However, at surgery, there was no definite evidence of rupture into the perimedullary cerebrospinal fluid. We postulate that the central canal could be a migration pathway for ruptured material into the brain.

국내에서 소아의 중증 결핵 환자는 사회경제적 발달과 BCG 백신의 적극적 접종으로 인하여 현저히 빈도수가 감소하였다. 저자들은 BCG 접종을 생후 4주에 실시했음에도 불구하고 가족내의 결핵 환자 발생이 인지되지 않아 조기 치료의 기회를 놓침으로서 속립결핵과 뇌결핵종의 합병증이 유발된 중증 결핵 환아 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

림프절염과 안면신경마비가 동반된 MRSA에 의한 세균성 중이염의 병력이 있는 생후 78일된 영아가 원발성 결핵성 중이염과 림프절염 및 폐결핵으로 확진된 증례를 경험하였다. 저자들은 세균성 중이염의 재발로 판단하고 결핵성 질환의 가능성을 간과하여 진단과 치료가 늦어졌다. 영아에게서 세균성 중이염으로 치료 종결 되었으나 재발 후 원발성 결핵성 중이염으로 확진된 증례는 매우 드물지만, 이와 같은 경우에도 반드시 결핵성 중이염의 가능성을 반드시 고려하여야 한다.

Oligodendrogiomas account for about 4 per cent of intracranial gliomas and surgery is known to be an essential first step to establish an accurate diagnosis and when oligodendrogliomas recur with or without anaplastic features after initial resection, radiation and chemotherapy consisting of the administration of procarbazine, lomustine, and vincristine are usually indicated. We report our experience of an excellent result with intraventricular methotrexate chemotherapy for a patient with disseminated anaplastic oligodendroglioma. A 29-year-old male patient presented with diplopia and headache for two months. MRI showed a irregular, faintly enhanced mass in the posterior fossa. The hisotological diagnosis was an anaplaplastic oligodendroglioma and he was treated with chemotherapy of PCV regimen and radiotherapy followed by surgery. CSF dissemination was revealed by a follow-up MRI during the period. Intraventricular methotrexate(0.175mg/kg) was given twice a week for 4 weeks through ommaya reservoir and the size of the multiple tumors was decreased significantly on follow-up MRI. This case report suggests that an aggressive treatment involving intravent-ricular chemotherapy may be helpful even when anaplastic oligodendrogliomas disseminates to leptomeninges.

본 연구는 1989년 10월부터 1992년 3월까지 아산재단 서울중앙병원에서 원발성 중추신경계 림프종으로 진단 받은 10명의 환자를 대상으로 하였다. 병리적 진단을 위한 조직은 5명에서 개두술에 의한 종양절제술로 얻어졌으며 나머지는 정위적 조직생검에 의해 얻어졌다. 성별분포는 남녀가 각 5명이었고 연령분포는 28세부터 72세로 평균연령은 45세로 나타났다. Working Formulation에 의한 세포아형은 7명에서 diffuse large cell type이었고 3명은 diffuse mixed cell type이었다. 전산화 단층촬영 결과 6명은 단일병소로 나타났으며 4명은 다발성병소로 나타났다. 치료는 전 환자가 전뇌방사선 조사를 4000 cGy/20 fx을 받은 후 원발병소에 2000 cGy/10 fx을 조사하여 총 6000 cGy를 시행하였다. 척수액 검사상 양성인 6명은 전뇌조사와 척수강내 항암제 투여를 받았으며 그중 1명은 척수강내 항암제 투여 3회 실시후 척수방사선 조사를 받았다. 척수액 검사상 음성인 4명중 3명은 전뇌조사만 실시했고 나머지 1명은 방사선 조사전 전신 항암제 투여를 받았다. 추적관찰기간은 7개월에서 26개월이었으며 평균 추적기간은 8개월 이었다. 1년 생존율은 86%이었고 2년 생존율은 69%로 나타났다. 현재까지 2명이 척수강내 재발 후 뇌실질내 재발로 사망했으며, 반면 7명의 환자는 방사선 치료후 병소가 완전히 없어졌다. 위의 결과로 볼때 원발성 중추신경계 림프종의 방사선 치료에 대한 월등한 초기반응과 원격 전이 가 적은 것을 고려하여 원발병소에 분할치료 방법들을 통한 전체 조사량을 증가시키는 것이 효과적이라고 생각되며 척수액 검사상 양성인 경우는 척수 방사선 조사와 척수강내 항암제를 함께 쓰는 좀더 적극적 치료가 필요하리라 생각된다.
