Cerebrospinal fluid leak presented with the C1-C2 sign caused by spinal canal stenosis: a case report.

Background: Intracranial hypotension is a disorder characterized by low cerebrospinal fluid (CSF) pressure typically caused by loss of CSF. Although some mechanisms account for the CSF leakage have been elucidated, spinal canal stenosis has never been reported as a pathological cause of intracranial hypotension. C1-C2 sign is a characteristic imaging feature, which indicates CSF collection between the spinous processes of C1 and C2, occasionally observed on magnetic resonance imaging (MRI) in patients with intracranial hypotension.

[Efficacy of percutaneous vertebroplasty for multiple myeloma].

Multiple myeloma is commonly associated with bony lesions and skeletal destruction. Percutaneous vertebroplasty (PVP) was performed in five patients with multiple myeloma for vertebral body fractures. Four patients reported a decrease in their pain after the procedure, and in all patients an improvement in their performance status could be noted.

[A case of idiopathic thoracic spinal cord herniation].

We report a case of idiopathic thoracic spinal cord herniation. A 63-year-old female came to our hospital complaining of a slowly progressive gait disturbance that began 5 years ago. She showed signs of a left dominant spastic paraparesis and sensory disturbance.

Fast inversion recovery magnetic resonance imaging with the real reconstruction method: a diagnostic tool for cerebral gliomas.

The fast inversion recovery (IR) technique was evaluated for the localization of gliomas. Fast IR imaging with real reconstruction and T1-weighted spin echo (SE) imaging before and after contrast administration were performed in 20 patients with gliomas. The tumor-to-white matter contrast ratio (TWCR), tumor-to-gray matter contrast ratio (TGCR), tumor-to-white matter contrast-to-noise ratio (TWCNR), and tumor-to-gray matter contrast-to-noise ratio (TGCNR) were calculated and compared.
