A case of a 63-year-old woman with subfrontal schwannoma of the left side is presented. The patient had a two-month history of recent memory disturbance and unstable gait. Computed tomography represented an isodense mass lesion with large and small cystic components in the anterior cranial fossa, enhancing homogeneously after intravenous injection of(More)
The case of a 14-year-old boy presenting with hypergammaglobulinemia (immunoglobulin (Ig)G and IgA) and a cerebellopontine angle tumor is reported. The tumor was histologically confirmed as meningioma infiltrated with plasma cells, lymphocytes, and histiocytes. Immunohistochemical studies showed that the infiltrating plasma cells were stained by antibodies(More)
It is very rare for neurosurgeons to encounter cases of spinal cord injury caused by a broken acupuncture needle. A 45-year-old man was referred to our clinic because of urinary retention about two weeks after acupuncture therapy (a needle was broken during treatment). The patient showed no motor weakness, or sensory disturbance. The needle was seen(More)
Anterior inferior cerebellar artery (AICA) aneurysms are very rare. We carried out four direct operations for AICA aneurysms including two distal AICA aneurysms using lateral suboccipital retrosigmoid approaches (LSRA). We successfully performed the clipping by LSRA. but hearing loss occurred except in one of our cases which involved a chronic term(More)
We report a case of intraorbital varix. A 16-year-old girl showed sudden left-sided exophthalmos after vomiting. After several episodes of vomiting, she developed complete loss of vision in the left eye, followed by orbital pain, disruption of eye movement, and periorbital swelling. No change in symptoms or signs was observed after the Valsalva maneuver or(More)
Numerous approaches have been used to access aneurysms of the vertebral artery(VA)-posterior inferior cerebellar artery(PICA)complex for microsurgical clipping. Here, we report the case of a patient with an unruptured aneurysm of the left VA-PICA complex that was successfully treated using a contralateral suboccipital approach. Computed tomography(More)
A 27-year-old woman presented with rebleeding from an intracranial arteriovenous malformation (AVM) 6 years after radiosurgery. Cerebral angiography demonstrated venous drainage change into a single drainer and cortical reflux due to drainage occlusion into the superior sagittal sinus. During surgery, multiple small feeders thought to be occluded on(More)
A 50-year-old female, who had a headache after Eustachian tube insufflation for her ear congestion, came to our hospital. CT and MRI revealed pneumocephalus and petrous ridge meningioma which destroyed petrous bone and air cells. Eustachian tube insufflation was considered to make the air coming into the middle ear, mastoid air cell and then into the(More)
In a period of ten years, since January 1996, we have encountered seven cases of posterior cerebral artery aneurysms (0.58% of surgically treated 1027 aneurysms in our hospital). Six of these cases were females (from 39 years old to 73 years old, average 54.5 years old). In five of the cases, neck clippings were performed, using the pterional approach for(More)
