From 1988 to 1990, we observed five cases of aseptic dural sinus and cerebral venous thrombosis, all in non-smoking women (age 18 to 47 years) receiving low dose oral contraceptives. Treatment consisted of full anticoagulation over 2 to 6 months, over which time the neurologic symptoms disappeared almost completely. Extensive tests of the blood clotting system in 4 patients after 6 to 19 months revealed a reduction of free protein S in 2 patients with a history of contraceptive use over several years, and normal results in 2 patients in which the sinus thrombosis occurred within the first 6 weeks of use of the oral contraceptive. Whether the protein S deficiency was congenital or caused by the oral contraceptive cannot be decided retrospectively. Even modern oral contraceptives seem to lead to an increased incidence of sinus thrombosis. Initial symptoms of sinus thrombosis include headache and somnolence, followed either by focal neurologic deficits (often associated with focal seizures) or by signs of increased intracranial pressure. CT scans show venous infarcts or general brain edema and may specifically show the "empty triangle sign" and "delta sign". The CT scan may also be normal if focal neurologic deficits are absent. MRI is favoured as it can directly show the thrombosed sinus or veins. Differential diagnosis includes arterial stroke, brain tumor, encephalitis or "benign intracranial hypertension", which should only be diagnosed after sinus venous thrombosis has been appropriately ruled out. Recently, full anticoagulation has been recommended as therapy.

Vogt-Koyanagi-Harada syndrome is a rare disease, which probably has a cell-mediated autoimmune pathogenesis, marked by ocular (anterior and/or posterior uveitis), dermatological (poliosis, canities, vitiligo) and neurological (meningo-encephalitis) disorders of variable severity in variable combinations. The clinical pattern in the case reported here showed severe neurological involvement (headache, ataxia and confusional state) followed by anteroposterior uveitis. Instrumental investigations (cerebrospinal fluid, VEPs, BAEPs, EEG, CT and MRI brainscans) confirmed the diagnosis. The response to cortisone therapy was excellent. We emphasize the importance of the neuroradiological investigations, because of their peculiarities, and review the reports of cases with marked meningo-encephalitic impairment, given the dearth of reports in the neurological journals.

Higher cerebral dysfunctions such as aphasia, apraxia and agnosia have seldom been reported in multiple sclerosis (MS). 12 year-old right-handed boy felt unsteadiness of the body and headache for several days. Two months later, he had the same episode and complained of visual disturbance, and weakness and sensory disturbance on the face and the extremities. Additionally, he showed amnestic aphasia, acalculia, ideomotor apraxia, finger agnosia and right-left disorientation. Cerebrospinal fluid examinations revealed increases IgG, myelin basic protein and neuron specific enolase (11%, 25 ng/ml and 28.8 ng/ml, respectively). X-ray CT scan and MRI-CT examinations revealed sclerotic lesions on the left parietal white matter and the right mid-brain. The diagnosis was made as MS. He was treated with m-PSL (methyl-prednisolone) pulse therapy for three weeks and consecutively treated with PSL for four weeks. He recovered gradually, but visual disturbance and facial palsy remained. After seven months MRI-CT showed a high signal intensity on the left parietal white matter in spite of the disappearance of the lesion on X-ray CT scan. We suggest that these higher cerebral dysfunctions may result from the lesion of the left parietal white matter which produces a disconnection between each cortical area.

A case of solitary syringobulbia without syringomyelia diagnosed by MRI was reported. A 63-year-old female, who had a history of progressive gait disturbance for 9 months, was admitted to our department because of severe headache. Neurological examination revealed that the patient was suffering from right pyramidal sign as well as left deep sensory disturbance without apparent impairment of cranial nerves or nystagmus. The somatosensory evoked potential stimulated by the left median nerve showed delay in latency and low amplitude, however, the auditory brainstem response showed normal records bilaterally. A syringobulbia associated with platybasia, basilar impression, obstructive hydrocephalus and Arnold-Chiari malformation was diagnosed by the neuroradiological examinations including plain X-ray films of the skull, CT scan and MRI of the brain. Subsequent to the decompression around the cisterna magna by suboccipital craniectomy and laminectomy of the atlas, the opening of the Foramen Monro which was obstructed by a thick membrane was carried out, and prevention of communication between the fourth ventricle and the syrinx was accomplished by using a piece of muscle. This operative procedure was thought to be compatible with Gardner's operation for syringomyelia. The patient showed gradual improvement of gait disturbance as well as headache 3 months after surgery, and this neurological improvement was proved by decrease in the size of the known syringobulbia on MRI, and by normalized somatosensory evoked potential stimulated by the median nerve. Pathophysiology of the solitary syringobulbia with relatively acute onset of the neurological symptoms was assumed to have taken place in the following manner.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of intraosseous meningioma at the posterior fossa was reported. Intraosseous meningioma is very rate and only six cases have been reported in Japanese literature. A 64 year-old woman complained of progressive headache and was admitted to Ichinomiya Neurosurgical Hospital. On admission, neurological examination did not reveal any abnormalities. However, plain skull X-p showed a hyperostotic lesion in the right posterior fossa. CT scan demonstrated homogeneously enhanced mass by contrast medium. MRI showed a mass lesion of the posterior fossa on T1 and T2 weighted images. The right vertebral angiogram showed an avascular area in the right posterior fossa and no tumor stain. The tumor, which was partially attached to the underlying dura, was successfully removed surgically. The operative finding confirmed an intraosseous meningioma which had arisen from the right asterion. The post operative course was uneventful. Histological examination revealed fibroblastic meningioma.

A 33-year-old woman developed headaches, papilledema, and evanescent neurologic signs. MRI demonstrated thrombosis of the sagittal, transverse, and sigmoid sinuses. After initial heparinization and three months of oral anticoagulation therapy, papilledema was still present but the neurologic signs and symptoms had markedly improved. Repeat MRI scan revealed improvement in all dural thromboses.

A 32-year-old primigravida showed signs of pre-eclampsia before delivery of a healthy boy at term. The CSF-space was accidentally punctured during epidural anaesthesia in labour. One day later hypertension was noted and the patient had a single generalized fit. For the next three weeks she had postural headaches, fluctuating hypertension, intermittent hearing loss and double-vision. On the 22nd day of postpartum, the patient had the first of a series of partial and later generalized seizures, followed by hemiparesis, alteration of consciousness, and finally slow recovery with corticosteroid therapy. Bilateral subdural effusions and generalized meningeal thickening were found on MR scans. Repeated MRI excluded sinus thrombosis and documented the response to treatment.

The patient who presents with a severe and acute headache should be evaluated radiographically with CT. The key diagnosis to make in this situation is hemorrhage, either subarachnoid or intraparenchymal. Computed tomography is more sensitive to acute hemorrhage than is MRI. When the patient is stable, MRI frequently contributes information to narrow the diagnostic possibilities, because vascular malformations and certain parenchymal lesions have a characteristic appearance on MRI. Hydrocephalus may also present acutely and is easily seen on CT or MRI. In a patient may show WMF and atrophy. The patient with trigeminal neuropathy may demonstrate central or peripheral lesions. In temporomandibular joint dysfunction, conventional tomography and MRI are frequently used. Magnetic resonance imaging shows excellent detail of the disk and surrounding soft tissues, whereas tomography better demonstrates bony changes. When a history of trauma is present, MRI may show a subacute subdural hematoma. These collections are easily seen on MRI, even when isodense on CT. Evidence of old shear injury is also well seen on MRI. Finally, neoplastic, inflammatory, congenital, and idiopathic sources of headache may be demonstrated by either MRI or CT, depending on presentation. MRI will generally show superior characterization.

A 47 year-old woman had been suffering from exertional headache for 2 1/2 years. Neurological examination was normal. X-rays of the skull and cranio-cervical junction and CT were normal. MRI sagittal sections disclosed a Chiari type I malformation. The headache disappeared after occipital craniectomy and atlas laminectomy.

We report the case of a 25-year old man with vestibulocochlear and ocular impairment compatible with Cogan's syndrome. Later on, severe headache developed. CT scan showed an ischaemic lesion in the right frontal lobe. Magnetic resonance imaging demonstrated multiple bilateral nodular lesions on T2-weighted sequences. These were unmodified at a second MRI examination performed six months later. Under corticosteroids, the neurological and ophthalmic symptoms disappeared, but the patient remained deaf. We believe that this patient had vasculitis involving the brain, with infarcts. To our knowledge, no case of Cogan's syndrome with cerebral magnetic resonance imaging has yet been reported.
