The effect of the longitudinal stretching force of the spinal cord on intramedullary pressure was investigated using our method for measuring intramedullary pressure of the spinal cord with implanted balloons. The transverse compressive force against the posterior wall of the spinal column was excluded by measuring the intramedullary pressure during flexion of the head with the middle and lower...

nant, small, round cell tumor that occurs mostly in children or young adults. The most common localization of PNETs is the cerebellum, and is also known as a medulloblastoma. PNETs may also arise in the cerebrum, brainstem, pineal gland, spinal cord, and peripheral nerves (1). Primary spinal PNETs are rare and only 32 cases have been reported in the literature (2-5). Primary spinal PNETs can ar...

BACKGROUND AND PURPOSE Studies systematically evaluating the detection of intramedullary spinal cord metastasis with PET are lacking. Our purpose was to evaluate the visibility of intramedullary spinal cord metastasis on PET in a single institutional series and to correlate PET and MR imaging features. MATERIALS AND METHODS Patients were included if pretreatment MR imaging identifying an intr...

We analyzed IR thermographies of 137 spinal cord tumor patients. Thermography (+) with level correlation was 67.8%, symptom correlation was found 28.8% with local pain, 81.1% with radiculopathy. Myelopathy (+) thermography was 71.9% in cervical level, 61.5 % in thoracic, 75.6% with para(quadri)paresis and over 100% with Brown-Sequard syndrome. For the extradural or IDEM tumors, thermography rep...

Subependymoma of the cord are rare tumors with very few cases described in the literature. They represent a diagnostic dilemma as far as imaging and histopathology is concerned. They are biologically benign with low proliferative index, hence postoperative prognosis is very good. We present a case of a 42-year-old male patient with an intramedullary Subependymoma located within the central cana...

Two cases of very rare intramedullary spinal cord metastasis from colon carcinoma and renal carcinoma were treated primarily by microsurgical excision. A 44-year-old female presented with colon carcinoma metastasis manifesting as complete neurological deficit. She had undergone colon resection 2 years previously for colon carcinoma. The tumor was excised by microsurgery with megadose steroid th...

Six cases of syringomyelia associated with intramedullary tumor were examined by metrizamide myelography and delayed computed tomography. All cases showed opacification of syringomyelic cavities 7-24 hr after myelography. This finding suggests that metrizamide can pass through the cord substance from the subarachnoid space into a syrinx cavity in noncommunicating types of syringomyelia. It supp...
