[Two cases of main trunk artery occlusion associated with multiple cerebral aneurysms].

We report 2 cases of multiple aneurysms (AN) associated with main trunk artery occlusion. CASE 1: A 52-year-old male was admitted to our hospital with dysarthria and weakness of the right side of the body. Computed tomography (CT) showed cerebral infarction in the left corona radiata.

[A case of rheumatoid factor-positive hypertrophic spinal pachymeningitis].

A 54-year-old female was admitted to our hospital with the complaint of progressive gait disturbance, starting with left abdominal pain 1 month previously. She developed acute paraparesis and stocking-anesthesia type sensory disturbance within a few days. MR imagings on admission, revealed an encircled subdural mass at the Th1-9 vertebral level, and her spinal cord was compressed at several places at the Th5-6.

[A case of high-aged idiopathic spinal cord herniation from dural defect].

Idiopathic spinal cord herniation was assumed to be a rare disease. However, the incidence of discovering this condition appears to have been increasing recently with advances in neuroradiological diagnosis using magnetic resonance imaging (MRI) and computed tomographic myelogram (CTM). We present herein an operated case of high-aged idiopathic spinal cord herniation.

Delayed hemorrhage from completely obliterated arteriovenous malformation after gamma knife radiosurgery.

A 43-year-old female was treated with gamma knife radiosurgery (GKS) for right frontal arteriovenous malformation (AVM) manifesting as absence seizures. Complete nidus obliteration was confirmed on angiography 4 years after GKS. However, she experienced recurrence of her previous seizures and delayed hemorrhage occurred within the treated nidus, despite absence of abnormalities by repeated angiography 81 months after GKS.

[Case of clipping of a ruptured aneurysm of the posterior cerebral artery (P2) via the transchoroidal-fissure approach].

A 59-year-old female was found to be drawn in a swimming pool and transferred to our hospital. The patient was comatose on admission (Hunt & Kosnk: Grade IV). Computed tomography (CT) showed diffuse subarachnoid hemorrhage (SAH) with thick hematoma in the left ambient cistern.

"Kissing aneurysms" of the anterior communicating artery treated with coil embolization.

Purpose: To present a case of kissing aneurysms of the anterior communicating artery treated with endovascular coil embolization and discuss the advantages and disadvantages of this technique compared with neck clipping.

Case Report: A 48-year-old man became drowsy and was admitted to the hospital; he had right hemiparesis and aphasia. Computed tomography revealed diffuse subarachnoid hemorrhage; diagnostic angiography identified an aneurysm at the left A1-A2 junction of the anterior communicating artery and another in the distal anterior cerebral artery (ACA).

[Currarino triad: a case report].

The authors report a case of Currarino triad with a combination of anterior sacral meningocele and mature teratoma, sacral body deformity, anorectal stenosis, and tethered cord. A newborn girl suffered from vomiting, abdominal distension and constipation. Initially, a diverting colostomy was performed at the age of one month.

[A surgical case of tectal cavernous malformation presented by hydrocephalus].

We report a surgical case of tectal cavernous malformation presented by hydrocephalus. This 30-year-old man suffered from headache and nausea due to an obstructive hydrocephalus caused by a cavernous malformation in the tectum. Magnetic resonance (MR) images on admission showed a small lesion depicted as isointensity on the T1-weighted image, hyperintensity on the T2-weighted image, and accompanied with peripheral low-signal intensity rim, suggesting a tectal cavernous malformation.
