Objectives: Patients with malignant gliomas have an even worse prognosis than other cancer patients, and they sometimes undergo surgery and chemo-radiotherapy without having been informed of the nature of the disease and its prognosis in Japan. Often, patients with glioblastoma are only told that they have a brain tumor, although other family members are told of the real diagnosis and prognosis. Since patients with glioblastoma, often experience a rapid deterioration in their condition, they usually do not have enough time to seek a second opinion regarding their disease. We surveyed neurosurgeons in Japan with regard to their policies and attitudes concerning the disclosure of a diagnosis of glioma and their thoughts on the end-of-life care of glioma patients., Methods: A survey was performed in November, 2007. A questionnaire was sent by e-mail to 259 participants who planned to attend the 25th Brain Tumor Conference in Japan., Results: One hundred and thirty-two participants (51%) returned the questionnaire. Almost all the respondents were neurosurgeons specializing in malignant brain tumors. The percentages of respondents who informed their patients of a diagnosis of grade 2 astrocytoma, grade 3 or grade 4 glioblastoma were 73%, 57% and 37%, respectively. More than 80% of all glioblastoma patients were only told that they had a malignant brain tumor. Sixty-eight percent of the doctors told the family members, but not the patients, of the real diagnosis. The neurosurgeons' policies and attitudes toward end-of-life care for patients with gliomas were also analyzed., Conclusions: Most neurosurgeons have difficulty disclosing a diagnosis of glioma and providing end-of-life care. This survey will help to develop guidelines regarding disclosure and the decision to pursue end-of-life care for patients with gliomas. (Received : March 19, 2009, Accepted : June 8, 2009)

A 22-year-old woman was involved in a motor vehicle accident and suffered a craniofacial injury. The patient was treated conservatively with a diagnosis of cerebral contusion in the frontal base confirmed with MR images. When the patient regained consciousness one week after the accident, she had a complete form of bitemporal upper quadrantanopia. A bone window level CT scan showed a linear fracture in the middle of the frontal base running longitudinally and extending posteriorly down to the sella turcica and clivus. Axial MR images parallel to the optic pathway revealed a T2 bright lesion in the anterior half of the optic chiasm. The patient recovered gradually and returned to her previous life-style six months later without complaining of diplopia, but her visual field defect was left unchanged. Traumatic chiasmal syndrome is rare and usually presents bitemporal hemianopsia. Very rarely, bitemporal quadrantanopsia has been reported. Given the anatomical structure that the neural fibers from the lower nasal part of the retina run posteriorly in the optic nerve and cross the anterior half of the optic chiasm to enter the contralateral optic tract, the lesion in the optic chiasm seen in the MR images seemed to be the causative lesion of bitemporal upper quadrantanopsia in our patient. The optic chiasm appeared to be injured by a laterally stretching force exerted in an antero-posterior direction when the medial basal fracture occurred.
