Gliofibroma is an extremely rare biphasic tumor with an astrocytic and benign mesenchymal component, which commonly occurs within the first two decades of life. The exact biological behavior of the tumor is not fully understood. Therefore, it is not listed as a distinct entity in the current World Health Organization classification of central nervous system tumors. Here, we describe a rare case of gliofibroma, which was located on the medial temporal lobe in a 61-year-old woman. Preoperatively, we misdiagnosed it as a meningioma because it was a well-demarcated and well-enhanced extra-axial mass with calcification and bony destruction. On the histopathological and immunohistochemical examination, the tumor consisted of a mixture of glial tissue and mesenchymal tissue and it was finally diagnosed as a gliofibroma. To our knowledge, this case of intracranial gliofibroma is in the oldest patient ever reported.

Intracranial involvement in multiple myeloma patients takes up around 1%, and is usually known to be present in the parietal bone or skull base in cases of skull vault involvement, while it presents in the dura and parenchyma in cases of intracranial involvement. Primary pachymeningeal invasion is even rarer with extremely rapid progression and very poor prognosis. It is our intent to report a case in which we had to differentiate multiple myeloma with other metastatic tumors, lymphoma, and leukemia with intracranial involvement. Our patient showed an osteolytic lesion of the skull with dural involvement and subdural mass formations.

Intracranial chloroma may occur in leukemia, although they are rare. A 23-year-old female complained diplopia. Brain magnetic resonance MR imaging showed tumors in the both cavernous sinus, both tentorial and anterior falx. Gamma-Knife radiosurgery was performed with maximal dose; 20Gy, marginal dose; 10Gy. Peripheral blood smear revealed leukemia, and bone marrow aspiration biopsy showed acute lymphocytic leukemia. Two weeks later, MR image for the stereotactic biopsy noticed markedly decreased tumor size. Biopsy result was lymphocytic leukemia. She received conventional radiation therapy, chemotherapy, and bone marrow transplantation. Brain involvement by acute lymphocytic leukemia is very rare. Even though chloroma are sensitive to radiation therapy, prognosis is poor because of the gravity of the underlying disease and association with impending blast transformation. The authors reports a intracranial chloroma by acute lymphocytic leukemia.

연세대학교 의과대학 세브란스병원에서는 1988년 8월 10MV 선형 가속기를 이용한 방사선 뇌수술(radiosurgery, stereotactic external beam irradiation)을 시작한 이래 1991년 12월까지 총 24예의 두개강내 종양에 대하여 방사선 뇌수술을 시행하였다. 대상 환자들의 조직학적 유형은 뇌수막종이 5예, 두개인두종이 3예, 악성임파종이 1예, 전이성 뇌종양이 2예 있었다. 대상환자들은 몇가지 다른 질병상태에서 방사선 뇌수술을 받았는데, 10예는 뇌정위적 생검이나 신경방사선학적 영상만으로 진단을 한 후 일차적인 치료로 방사선 뇌수술을 시행했으며, 9예에서는 수술 후 잔류 종양에 대하여 방사선 뇌수술을 시행하였다. 또 3예에서는 방사선 치료후 재발한 종양에 대해 구제요법으로 시행하였고, 2예에서는 외부 방사선 조사와 함께 추가 방사선조사로써 시행되었다. 6개월 이상 추적 조사된 환자 16명 중에서 7명(뇌수막종 2예, 신경교종 4예, 악성임파종 1예)이 CT Scan 또는 MRI상 종양의 완전 소멸을 보였고 나머지 9예는 모두 종양 크기의 감소를 보였다. 방사선 수술시 급성 부작용은 없었고 4예에서 만성 합병증이 나타났는데 3예에서 신경학적 증상의 발현과 함께 CT Scan상 뇌부종이 나타났었고 1예의 두개인두종에서는 방사선에 의한 시신경 손상으로 생각되는 시력 소실이 있었다. 저자들의 경험 예들은 조직학적 유형이 다양하고 증례수가 많지 않고 추적 조사 기간이 짧기 때문에 결론을 얻기 어렵지만 정위적 방법으로 종양에 다량의 방사선을 일시에 조사함으로써 완전 관해까지의 우수한 종양 제어효과를 얻을 수 있었다. 그러나 여러가지 종류의 뇌종양의 치료에 있어서 방사선 뇌수술이 생존율 향상이나 삶의 질의 향상에 기여할 수 있는지를 알기 위해서는 더 많은 증례를 통하여 경험을 축적하여야 할 것이다. 각각 $48{\pm}20W$ 및 $39{\pm}19W$이었으며, 폐 가온군이 간 가온군 보다 높았다(p<0.05). 6) 가온에의한 식도내 온도가 폐의 온도보다 $1.1{\pm}0.9^{\circ}C$높았다(p<0.05). 이상과같은 결과는 기낭성기관인 폐도 RF의 보다 높은 출력 이 소요되기는 하나 온열요법을 시행하였을 때 충실성기관인 간과 마찬가지로 종양치료에 유효한 $42^{\circ}C$-$43^{\circ}C$까지 잘 가온될 수 있음을 입증 하였다. 또한 폐의 온열요법시 종격동은 보다 높은 온도에 도달함으로 종격동의 열손상에 대한 고려가 필요함을 시사한다.r=0.990)로 각각 표시되었으며 각 간의 기울기에 대한 유의차는 없었다.18. 혈청중 LH와 total protein과의 상관계수는 +0.947이다. 19. 혈청중 FSH와 total protein과의 상관계수는 +0.709이다. 20. 혈청중 FSH와 triglycerides와의 상관계수는 +0.549이다. 21. 혈청중 estradiol-$17{\beta}$와 triglycerides와의 상관계수는 +0.673이다. 22. positive feedback mechanism에 의해서 LH, FSH와 estradiol-$17{\beta}$는 간을 자극시켜 albumin, total protein 및 triglycerides를 분필시킴으로서 난황형성(vitellosenesis)에 관여하는 것으로 나타났다.$21.4\%$로 나타났고 이들을 제외한 나머지 사람들은 보통 속도 혹은 충분한 시간을 가지고 식사를 하였다. 평소 식사량은 조금 적게 혹은 적당하게 섭취하는 사람이 대부분이었으며 남자가 여자보다는 배부르게 먹는 경

Plasma cell myelomas generally manifest as bone or soft-tissue tumors with variable mass effects, pain, and infiltrative behavior. Extramedullary involvement occurs most commonly in the spleen, liver, lymph nodes, and kidneys, but intracranial involvement in plasma cell myeloma is a rare extramedullary manifestation. These authors recently encountered a case of intracranial involvement of plasma cell myeloma. A 69-year-old man was hospitalized for headache and mental changes. Brain CT showed subdural hemorrhage caused by plasma cell myeloma. Plasma cell myeloma with intracranial involvement has poor prognosis, and the patient in this case died from acute complications, such as subdural hemorrhage. Based on this case report, it is suggested that more effective treatment regimens of plasma cell myeloma with intracranial involvement be developed. Moreover, a screening method and decision on the appropriate time for intracranial involvement are needed for plasma cell myeloma patients.

Brain tumors are a mixed group of neoplasms that originate from the intracranial tissues and the meninges with degrees of malignancy varying greatly from benign to aggressive. Not much is known about the epidemiology of primary malignant brain tumors (PMBTs) in our population in North-East India. In this analysis, an attempt was made to identify the age groups, gender distribution, topography and different histological types of PMBT with data from a hospital cancer registry. A total of 231 cases of PMBT were identified and included for the present analysis. Our analysis has shown that most of PMBT occur at 20-60 years of age, with a male to female ratio of 2.3:1. Some 70.5% of cases occurred in cerebral lobes except for the occipital lobe, and astrocytic tumors were the most common broad histological type. In our population the prevalence of PMBT is 1% of all cancers, mostly affecting young and middle aged patients. As brain tumors are rare, so case-control analytic epidemiological studies will be required to establish the risk factors prevalent in our population.

Objective : We investigated the effectiveness of stereotactic gamma knife Radiosurgery (GKR) for radioresistant brain metastases with the impact upon histology. Methods : Between April 2004 and May 2011, a total of 23 patients underwent GKR for 67 metastatic brain tumors from 12 renal cell cancers, 5 sarcomas and 6 melanomas. The mean age was 56 years (range, 18 to 79 years). Most of the patients were classified as the Radiation Therapy Oncology Group recursive partitioning analysis class II (91.3%). The synchronous metastasis was found in 6 patients (26.1%) and metachronous metastasis in 17 patients (73.9%). We analyzed the local control rate, intracranial progression-free survival (PFS) and overall survival (OS). Results : The mean tumor volume for GKR was 2.24 cc and the mean prescription dose was 19.4 Gy (range, 10 to 24) to the tumor margin. Out of metachronous metastases, the median duration to intracranial metastasis was 3.3 years in renal cell cancer (RCC), 2.4 years in melanoma and 1.1 years in sarcoma (p=0.012). The total local control rate was 89.6% during the mean 12.4 months follow-up. The six-month and one-year local control rate was 90.2% and 83% respectively. Depending on the pathology, the control rate of RCC was 95.7%, sarcoma 91.3% and melanoma 80.5% during the follow-up. The common cause of local failure was the tumor bleeding in melanoma. The median PFS and OS were 5.2 and 8.4 months in RCC patients, 6.5 and 9.8 months in sarcoma, and 3.8 and 5.1 months in melanoma. Conclusion : The GKR can be one of the effective management options for the intracranial metastatic tumors from the radioresistant tumors. The melanoma showed a poor local control rate compared to other pathologies because of the hemorrhage.

Germinomas of the central nervous system are rare embryonal tumors(accounting for less than 1% of intracranial neoplasms) that may be located in the pineal region, in the floor of the third ventricle, or in the suprasellar area. We report a case of germinoma developed in periventricular deep white matter without pineal region tumors or suprasellar masses. The 19-year-old male patient presented with slowly progressing headache, dizziness, photophobia, and dysarthria. Initial brain MRI revealed a irregular and dense enhancement from lateral ventricles to 4th ventricle. The stereotactic biopsy of tumor and histologic examination revealed the germinoma. Craniospinal axis radiation therapy was performed. After radiation therapy patient was improved and no neurologic sequelae was seen at discharge. Periventricular germinomas without pineal or suprasellar lesion are very rare. The radiation therapy, as in our case, is beneficial as with other intracranial germinomas. Stereotactic biopsy of periventricular germinoma provides precise pathologic diagnosis and thus allows more specific management.

A group of 49 patients with neurogenic tumor in head and neck except intracranial tumor & Von-recklinghausen's disease was treated at the Department of Surgery. Presbyterian Medical Center during 12 years from January, 1980 to December, 1991. Of the 49 cases, 24 cases were neurilemmoma, 23 cases neurofibroma and 2 cases malignant schwannoma. The lateral cervical region was the commonest location of the neurogenic tumors, 24 cases (49%) arose from posterior triangle of neck and 12 cases from anterior triangle of neck. The origin of nerve was identified in 28 cases(57%). Cervical plexus(10 cases) and brachial plexus(7 cases) were most commonly affected. The most common site of neurogenic tumors arose from cranial nerve was anterior cervical triangle.

Brainstem gliomas remain an important oncologic problem in the pediatric age group. These tumors constitute between 10 and 15% of all intracranial childhood tumors and despite advanced in the diagnosis and treatment of children with brain tumors, brainstem gliomas are still almost invariably rapidly lethal. We have few of clinical records of braintumors and admission case in the oriental medical hospital, classifications of tumor, symptoms and etc, specially in the pediatrics, so we introduce a case of a 7-year-old child with brainstem glioma which is diagnosised by MRI in our hospital.
