Glioblastoma multiforme (GBM) is located most frequently in the cerebral hemispheres. Glioblastoma presenting as an extraaxial mass of cerebellopontine angle (CPA) is very rare in adults. We report a rare case of GBM arising in the CPA. The patient was a 71-year-old female, who complained of progressive gait disturbance and poor memory. Initial magnetic resonance imaging (MRI) revealed a $1.4{\times}1.3cm$ mass in the left CPA, with broad base to the petrous bone, showing homogenous enhancement. Follow-up MRI showed a rapid increase in size of mass ($2.7{\times}2.2cm$) with a necrotic portion. A stereotactic biopsy was done under the guidance of navigation system, and the histopathologic diagnosis was GBM, World Heath Organization grade IV. Further surgical resection was not performed considering her general condition, and the patient underwent concurrent chemotherapy with radiation therapy. Although rare, the possibility of glioblastoma should be included in the differential diagnosis of atypical CPA tumor.

Most of intradural epidermoid cyst arise as slowly growing extraaxial lesions but purely intracerebral epidermoid cysts are rare. A 39-year-old female presented with a headache during several months. Brain computed tomography [CT] scan showed a mass lesion in the both frontal lobe with heterogenous density approximately $5{\times}5cm$ in size. Magnetic resonance imaging [MRI] revealed a mass of heterogenous signal intensity on T1, T2-weighted image and faint enhancement with gadolinium [Gd]. Through the both interhemispheric approach, mass was removed subtotally except the calcified portion tightly attached to the corpus callosum. The patient discharged without neurological deficit. The authors report a case of epidermoid cyst in the corpus callosum and discuss the pathogenesis of the intraparenchymal epidermoid cyst.

Cystic Meningiomas are rare tumor. There is a clear prevalance in infants, according for $10{\sim}19%$ of all intracranial meningiomas in this age group, compared with only $2{\sim}4%$ in adults. But, reports of cystic meningioma have been increased in frequency since the introduction of computed tomography[CT] and magnetic resonance image[MRI]. Authors report two cases of cystic meningioma in adults. Radiological finding showed extraaxial mass with cystic component. Authors performed total surgical resection of the tumor mass and of the entire cystic component with cystic wall in both patients. Postoperative histopathological diagnosis of the tumor mass was a transitional meningioma in both patients. Both patients showed favorable prognosis and no recurrence findings in follow up MRI.

A 43-year-old male presenting with headache and dizziness underwent craniotomy and gross total resection of an extraaxial tumor was achieved via left occipital interhemispheric approach. The tumor was diagnosed as papillary meningioma arising from the left falcotentorium with such pathologic characteristics of bronchoalveolar adenocarcinoma. At postoperative day 40, he developed generalized tonic clonic seizure and then progressed to a status epilepticus pattern. Brain magnetic resonance imaging showed irregular leptomeningeal enhancement with a significant peritumoral area. Through a cerebrospinal fluid (CSF) study, we identified the meningioma cells of the papillary type from the CSF. At the postoperative day 60, he fell into semicomatose state, and the computed tomography imaging showed low density on both cerebral hemispheres, except the basal ganglia and cerebellum, with overall brain swelling and an increased intracranial pressure. He died on the following day. We experienced a rare case of a papillary meningioma with leptomeningeal seeding.

수모세포종은 주로 소뇌 충수에서 기원하는 것이 대부분이며, 천막에서 기원하는 경우는 아주 드물다. 본 보고는 심한 두통, 오심, 그리고 구토 등의 증세로 내원한 12세 남자 환자의 경우이다. 자기공명영상 검사 상 좌측 천막에서 기원한 것으로 보이는 종양이 있었으며, 이를 수막종으로 의심하고 수술적 치료를 시도하였다. 병리학적 검사 결과는 수모세포종이었다. 이에 본 저자는 천막에서 기원한 비정형적인 수모세포종에 대한 문헌고찰과 저자가 경험한 증례를 보고하고자 한다.

Objective : To evaluate the role of cranial sonography and computed tomography in the diagnosis of neonatal intracranial hemorrhage and hypoxic-ischemic injury in an Indian set-up. Methods : The study included 100 neonates who underwent cranial sonography and computed tomography (CT) in the first month of life for suspected intracranial ischemia and hemorrhage. Two observers rated the images for possible intracranial lesions and a kappa statistic for interobserver agreement was calculated. Results : There was no significant difference in the kappa values of CT and ultrasonography (USG) for the diagnosis of germinal matrix hemorrhage/intraventricular hemorrhage (GMH/IVH) and periventricular leucomalacia (PVL) and both showed good interobserver agreement. USG, however detected more cases of GMH/IVH (24 cases) and PVL (19) cases than CT (22 cases and 16 cases of IVH and PVL, respectively). CT had significantly better interobserver agreement for the diagnosis of hypoxic ischemic injury (HII) in term infants and also detected more cases (33) as compared to USG (18). CT also detected 6 cases of extraaxial hemorrhages as compared to 1 detected by USG. Conclusion : USG is better modality for imaging preterm neonates with suspected IVH or PVL. However, USG is unreliable in the imaging of term newborns with suspected HII where CT or magnetic resonance image scan is a better modality.

목적 : 순차적인 뇌초음파 검사 후 신생아 중환자실을 퇴원하는 고위험 환아에서 시행한 자기 공명 영상의 유용성을 알아보고자 하였다. 대상 및 방법 : 총 121명의 신생아에서 시행한 412 초음파와 121 자기공명 영상을 후향적으로 분석하여 초음파 검사에서 발견된 뇌병변과 자기 공명영상에서 발견된 병변을 비교하였다. 뇌병변은 배아기질 출혈 및 뇌실 내 출혈, 그 밖의 여러 출혈과 뇌실질 손상을 중심으로 비교 분석하였다. 결과 : 총 242개의 측뇌실 중 30뇌실의 배아기질 출혈 (GMH)을 초음파로 진단하였고 자기공명영상으로 7개의 GMH를 추가로 진단할 수 있었으며 46개 뇌실의 출혈 (IVH)을 추가로 진단하였다. 출혈의 1/2/3/4 등급은 초음파에서 각각 24/8/13/0 뇌실에서 진단하였고 자기공명영상에서 3/49/10/2 뇌실에서 진단하였다. 그 외에 자기공명영상에서 대뇌 출혈 (4예), 소뇌 출혈(4예), 경막하 및 지주막하 출혈 (8예), 미만성 백질 신호강도 변화 (72예), 조직손실이 없는 작은 실질 병변 (4예), 뇌연화증 (2예), 그리고 뇌실확장 (5예)이 추가로 발견되었다. 결론 : 자기공명영상은 초음파 검사 후 두개강내 출혈과 뇌실질 손상을 추가적으로 진단하는 유용한 검사였으며 특히 뇌실 출혈과 백질 손상의 진단에 우수한 반면 배아기질 출혈은 초음파 추적검사가 더 유용할 것으로 생각한다.
