Craniopharyngioma is considered to be a benign intracranial tumor. Malignant transformation of craniopharyngioma has rarely been described. In this article, we report a case of ameloblastic carcinoma arising from a previously benign craniopharyngioma in a 42-year-old woman. The patient was diagnosed with craniopharyngioma in August 2004 and underwent(More)
OBJECT Brainstem gliomas are common in children and have the worst prognosis of any brain tumor in this age group. On the other hand, brainstem gliomas are rare in adults, and the authors of some clinical studies have suggested that this lesion behaves differently in adults than in children. In the present study, the authors test an orthotopic C6 brainstem(More)
Despite advances in microsurgery and the development of new endovascular techniques, the treatment of complex intracranial aneurysms remains a daunting challenge for neurosurgeons. In the present study, we retrospectively reviewed our experience of bypass surgery in the treatment of 93 cases of complex intracranial aneurysms. A series of 93 consecutive(More)
Bilateral cavernous carotid aneurysms (CCAs) are often not amenable to neurosurgical clipping or endovascular coiling. Here, we report the case of a 50-year-old female who presented with a 1-year history of gradual severe headache. Preoperative angiograms revealed bilateral CCAs. Among these findings, the right giant CCA had been trapped after the external(More)
Fusiform dilation of the internal carotid artery (FDICA) is an infrequent vascular complication following resection of suprasellar lesions in the pediatric population, and its course appears to be benign without apparent clinical symptoms. However, data correlating symptomatic FDICA with bypass surgery are scarce. The authors here report 2 symptomatic cases(More)
OBJECTIVE To evaluate the effectiveness of internal maxillary artery (IMA) - radial artery graft (RAG) - middle cerebral artery (MCA) bypass surgery for chronic arterial-sclerotic severe stenosis or occlusion of the internal carotid artery (ICA) or MCA. METHODS A retrospective study was conducted in 31 patients with ischemic cerebrovascular disease who(More)
This report presents a patient with medically intractable startle epilepsy who was treated with surgery. The ictal onset zone was further localized to a part of the premotor cortex on the basis of intracranial electroencephalography recording and surgical resection of the epileptogenic zone was done. The motor area close to the epileptogenic focus was(More)
