[A case of glomerulonephritis associated with ventriculo-atrial shunt].

Nephritis associated with a chronically infected ventriculo-atrial (VA) or ventriculo-peritoneal (VP) shunt is known as shunt nephritis. A 60-year-old woman who had a VA shunt implanted for hydrocephalus began to show intermittent low-grade fever of an unknown origin, as well as hypertension and lower leg edema. Laboratory findings showed renal insufficiency with proteinuria, and a percutaneous renal biopsy was performed.

[A case of multifocal fibrosclerosis presenting with chronic subdural hematoma].

Multifocal fibrosclerosis(MFS) is a rare disorder of unknown etiology, characterized by chronic inflammation with dense fibrosis and lymphoplasmacytic infiltration into the connective tissue of various organs. Recently, MFS was classified as IgG4-related systemic disease. In this paper, we report a 60-year-old man with no history of head injury presenting with chronic subdural hematoma(CSDH).

Single photon emission computed tomography of reversible magnetic resonance imaging abnormalities of deep cerebral venous thrombosis accompanied with malignant glioma.

Background: Deep cerebral venous thrombosis with reversible MRI findings in bilateral thalamus have been scarcely described in the literature, but none mentioned the SPECT findings such as in our case.

Case Description: A 43-year-old woman presented with cerebral venous thrombosis accompanied with malignant glioma. T(2)- and diffusion-weighted MRI showed high intensity with a mass lesion in the left frontal lobe and mild high and high intensity in the right frontal lobe, parietal lobe, and bilateral thalamus.

[Speech disturbance following myelography with iohexol: a case report].

Iohexol (Omnipaque) is a non-ionic contrast media for neuroradiology, which causes the neurological complications on rare occasions. A 63-year-old, righthanded female suffered from dysphemia 12 hours after myelography with iohexol via lumbar puncture. The initial cerebral computed tomography scan revealed the generalized contrast media uptake into the cisterns, which was typical to the finding after intrathecal iohexol injection.

[Calcified chronic subdural hematoma complicated with subcortical hemorrhage: case report].

The patient was a 46-year-old male, who suffered from mild head trauma in January 2002, and general convulsions with unconsciousness on February 28. Slight right hemiparesis and aphasia were presented after the epilepsy attack. CT scan revealed a large lesion of mixed density occupying the left temporal space.

[Aseptic meningitis as a complication caused by an allergic reaction after microvascular decompression: two case reports].

We report here two cases of patients complicated with aseptic meningitis after microvascular decompression (MVD). The first case, a 56-year-old female complained of headache with high fever 18 days after the MVD for right trigeminal neuralgia. The amount of cells in cerebrospinal fluid (CSF) had so much increased that bacterial meningitis was suspected.

[A dissecting aneurysm of the posterior inferior cerebellar artery was reduced spontaneously during conservative therapy: case report].

We report here a case of a patient with a dissecting aneurysm of the anterior medullary segment of the posterior inferior cerebellar artery (PICA) which presented with Wallenberg's syndrome. A 32-year-male presented with an unusual case of Wallenberg's syndrome due to a dissecting aneurysm of the PICA manifesting as a sensation of heaviness in the occipital region and vertigo. The occipital symptoms persisted and vertigo and vomiting developed after 6 days.

[The usefulness of 3D-CTA for the diagnosis of a ruptured aneurysm at the origin of the duplicated middle cerebral artery: case report].

Duplication of the middle cerebral artery is known as a rare anomalous vessel arising from the internal carotid artery and an aneurysm at the origin of the duplicated middle cerebral artery is very rare. We presented a case of ruptured aneurysm at the origin of the duplicated middle cerebral artery and discussed the usefulness of 3D-CTA (three-dimensional computed tomographic angiography) for its diagnosis. A 34-year-old female suffered from severe headache and was admitted to our hospital.
