Intramedullary spinal cord ganglioglioma presenting as hyperhidrosis: unique symptoms and magnetic resonance imaging findings: case report.

Hyperhidrosis is caused by a sympathetic dysfunction of the central or peripheral nervous system. Intramedullary spinal cord lesions can be a cause of hyperhidrosis. The authors report a rare case of intramedullary thoracic spinal cord ganglioglioma presenting as hyperhidrosis.

Dissection aneurysm of the radiculomedullary branch of the artery of Adamkiewicz with subarachnoid hemorrhage.

A 60-year-old female presented with sudden onset of severe headache and back pain, followed by nausea. The initial head computed tomography (CT) scan revealed posterior fossa subarachnoid hemorrhage (SAH). Spinal T(2)-weighted magnetic resonance imaging demonstrated SAH, and a homogeneous and slightly low signal intensity mass at T11.

Remote cerebellar hemorrhage after foramen magnum decompression surgery for Chiari I malformation--case report.

A 47-year-old woman underwent decompressive suboccipital craniectomy and C1 laminectomy with duroplasty in the prone position for Chiari malformation type I and syringomyelia. The arachnoid membrane was not injured. Intraoperative echography showed good enlargement of the subarachnoid space.

Intraoperative indocyanine green videoangiography for spinal vascular lesions: case report.

Background And Importance: In surgery of spinal vascular lesions such as spinal arteriovenous fistula or vascular tumors, assessment of feeding arteries and draining veins is important. Intraoperative digital subtraction angiography is useful but is invasive and sometimes technically demanding. Near-infrared indocyanine green (ICG) videoangiography is less invasive and has been reported as an intraoperative diagnosis of arterial patency during clipping surgery of cerebral aneurysms or bypass surgeries.

Identification of Ryu's segmentation of the liver using MDCT analysis.

Background: Couinaud's segmentation is widely used for clinical segmentation of the liver. Recently, a new method of liver segmentation was described by Ryu. In this method, the right posterior sector in Couinaud's segmentation is regarded as 1 segment, and the right anterior sector is subdivided into the antero-ventral segment (AVS) and the antero-dorsal segment (ADS), which are demarcated by the anterior fissure vein (AFV).

[Fracture of the cervical spine in ankylosing spondylitis. A case report].

We report a case of a 61-year-old man with ankylosing spondylitis who showed cervical spine fracture. The patient had fallen down on the floor and presented with severe neck pain. He was treated conservatively with a hard neck collar in an emergency hospital because of C7 body fracture without dislocation.

[Multiple small subcortical infarction required to distinguish from lacunar infarction: evaluation by use of diffusion-weighted imaging].

Lacunar infarctions are small lesions caused by occlusion of the deep and penetrating vessels. Occlusion of such vessels are resulted from thrombosis based on atherosclerotic change. However, we occasionally encounter a patient with lacunar infarction seemed to be caused by embolic mechanism, as who has had previous experience of TIA or presented with clinical symptoms suddenly.

[Chronological changes in the vasculature and the cerebral blood flow of two patients with isolated angiitis of the central nervous system].

Isolated angiitis of the central nervous system (IAC) is an inflammatory, rare vasculopathy confined to the central nervous system, and the exact etiology has remained uncertain. We report serial changes in the vasculature and the mean cerebral blood flow (mCBF) in two patients with IAC. The first patient, a 58-year-old female, had sudden onset of severe headache and CT 4 days later showed cerebral hemorrhage in the frontal lobe.

[Serial magnetic resonance angiography in a case with isolated angiitis of the CNS].

Isolated angiitis of the central nervous system (IAC) is an idiopathic type of vasculitis, exclusively affecting small to medium-sized blood vessels of the central nervous system. We report serial angiographical findings, mainly demonstrated with magnetic resonance angiography (MRA) in a case of IAC. A 58-year-old-female came to our hospital because of a sudden headache.

[A case of brainstem encephalitis diagnosed by stereotactic biopsy].

Brainstem encephalitis is a rare form of encephalitis which should be differentiated from cerebrovascular and neoplastic diseases. The authors report a case of viral brainstem encephalitis mimicking malignant lymphoma. A 55-year-old female was admitted to our hospital with gradually progressive diplopia and left hemiplegia.
