A 28-year-old Malay man presented with progressive paraparesis over a period of 6 months. Magnetic resonance imaging of the spine revealed a thoracic intramedullary spinal cord tumor at the T-7 level with homogeneous enhancement following intravenous gadolinium administration. Laminectomy and partial decompression of the tumor was performed. Histological examination of the tumor revealed features of spindle cell hemangioendothelioma. The patient was managed with limited field radiotherapy followed by systemic interferon therapy. Good neurological improvement was seen subsequently. The patient has survived 48 months with growth restraint at the primary site, although residual neurological deficit persists. Immunotherapy should be considered as a treatment modality for intramedullary hemangioendothelioma of the spinal cord after surgery and radiotherapy.
A new image transmission and teleconference system using international digital telephone services was established between Japan and Malaysia. This new system consists of an ordinary personal computer, image scanner, and terminal adapter for digital telephone lines. The quality of images transferred using this system was high enough for diagnosis and discussion except for images such as radiographs requiring huge data transfer. Transmission of one image took approximately 20 seconds. The cost performance was almost equal to the conventional mailing system. The most remarkable advantage of this new system is the high quality of transferred images, the cost and time performance, and security of the medical information. New communication systems using international digital networks including the internet may allow re-distribution of medical resources between advanced countries and developing countries in neurosurgery.
An 8-year-old girl presented with fibromuscular dysplasia of the intracranial vessels manifesting as ischemic stroke. Neuroimaging showed infarction of the right putamen and ipsilateral frontal white matter. Angiography revealed "string of beads" sign involving the terminal portion of the right internal carotid artery and the horizontal segment of the ipsilateral middle cerebral artery. She was treated conservatively. Magnetic resonance angiography at 2 months post ictus showed similar findings in the middle cerebral artery but improvement of the stenosis of the internal carotid artery. Her neurological deficits had almost resolved. Fibromuscular dysplasia should be part of the differential diagnosis of ischemia in children.
