Epidermoid cyst is generally regarded as congenital disease, and commonly related to other congenital spinal anomalies. However, it also develops iatrogenically. We report one rare case of epidermoid cyst that we experineced among intradural extramedullary tumors. A 21-year-old female patient was admitted to the hospital due to low back pain with radiating pain into a right lower extremity that...

Electrical activation of the auditory cortex has been shown to elicit an auditory sensation; however, the perceptual effects of auditory cortical microstimulation delivered through penetrating microelectrodes have not been clearly elucidated. This study examines the relationship between electrical microstimulus location within the adult rat auditory cortex and the subsequent behavior induced. F...

The malleability of object representations by experience is essential for adaptive behavior. It has been hypothesized that neurons in inferior temporal cortex (IT) in monkeys are pivotal in visual association learning, evidenced by experiments revealing changes in neural selectivity following visual learning, as well as by lesion studies, wherein functional inactivation of IT impairs learning. ...

There are few rerorts on delayed neurologic deficit after stab injury with a retained intraspinal foreign body and granuloma formation. This study reported a 24-year-old man presented with progressive neurologic deficits, an unusual case of delayed myelopathy with an intraspinal nonmetal foreign body granuloma, which was misdiagnosed as tuberculosis of neural arches before operation because the...

We present two cases of traumatic pneumorrhachis that is defined as air within the spinal canal. It is also known as pneumosaccus, intraspinal pneumocele, aerorachia, pneumomyelogram, or simply intraspinal air. Only few cases have been reported in the literature, and a review of the literature has exposed only 35 cases in epidural type and 18 cases in subarachnoid type. (J Kor Neurotraumatol So...

Cerebrospinal fluid-borne metastases were demonstrated by metrizamide myelography in 20 children with primary intracranial tumors, posterior fossa medulloblastomas being the most common. The lumbosacral region was affected most often, with nerve root thickening, nodularity, and irregularity of the thecal sac. Cord cloaking, nodularity, and meningeal disease were common in the cervical and thora...
