Clear-cell meningioma is a rare subtype of meningioma which occurs at a younger age and has a higher recurrence rate than other subtypes. We report two cases of clear-cell meningioma, one in the thoracolumbar spinal canal and the other in the cerebellopontine angle. Though the CT and MR imaging findings were not different from those of ordinary meningioma, after surgical removal the condition r...

The importance of the size and shape of the spinal canal in relation to the occurrence of symptoms of cord or root compression, especially when spondylotic changes supervene, has been recognised for some time. Most of the earlier work concerned the cervical region (Pallis, Jones and Spillane 1954), but in more recent years a similar condition has been fully recognised in the lumbar region also ...

Congenital and surgical defects of the neural arches of the spine have provided sonic windows and new applications for sonography in neuroradiology [1, 2]. The contents of the lumbar spinal canal can also be seen by an anterior approach, through the intervertebral disk, as illustrated in a recent atlas of sonography [3]. However, no previous report has been found on the use of sonography in the...

A 9-year-old girl was stabbed by aquarium glass fragments in her back, which entered adjacent to the S1 vertebra and stayed within the spinal canal adjacent to the L5 vertebra. Surgical removal of the glass fragments in the acute phase was performed to decrease the risks of delayed complications associated with the presence of the sharp and pointed glass inside the spinal canal and cauda equina...

Schwannoma originates from the sheath of spinal cord roots neurilemma or Schwann cells (so it is mainly called neurilemmoma or Schwannoma) and makes one third of primary spinal cord tumours [1-6]. The tumour localization is in various parts of spinal cord, but prevailsin cervical and thoracic, rare in lumbar and sacral regions [1-7]. It can grow exophytic above and below the dura of spinal cord...

A 16-year-old boy vomited due to heatstroke during a soccer game but continued to train hard after the game. He was admitted to our hospital for chest discomfort three days later. Chest radiograph demonstrated pneumomediastinum, and computed tomography of the neck revealed emphysema within the spinal canal (Picture 1A) at cervical level 5 (Picture 1B, red arrows). Barium esophagography revealed...

This study was to evaluate the morphological features of degenerative spinal stenosis and adequacy of lateral canal stenosis decompression via unilateral and bilateral laminectomy. Measurements of facet joint angulation (FJA), mid facet point (MFP), mid facet point distance (MFPD), the narrowest point of the lateral spinal canal (NPLC) and the narrowest point of the lateral spinal canal distanc...

DESCRIPTION A 57-year-old man was admitted to the emergency department with blunt thoracic and abdominal trauma after being hit by a tree. CT of the thorax and abdomen was performed. Abdominal CT showed a large retroperitoneal haematoma secondary to an injury of celiac trunk; thoracic CT showed a right haemo-pneumothorax, a pneumomediastinum, a large basal lung contusion, a small dorsal right s...

A variety of cystic lesions may develop in spinal canal. These cysts can be divided into intramedullary, intradural, extradural, cervical, thoracic, lumbar, and sacral cysts according to anatomical presentation, as well as arachnoid, meningeal, perineural, juxtafacet, discal, neurenteric cysts, and cyst-like lesions according to different etiologies. Mechanisms of initiation and growth vary for...

The shallow lateral recesses of the trefoil shape of the lumbar spinal canal have been implicated in the production of the spinal stenosis syndrome. In the present study, 485 skeletons of South African Blacks and Whites were examined in order to establish the incidence and possible genesis of the trefoil configuration. The overall incidence was 14 per cent, with little variation between the sex...
