Patterns of chronic adhesive arachnoiditis following Myodil myelography: the significance of spinal canal stenosis and previous surgery.

109 patients who had undergone Myodil myelography on at least one occasion were identified. The patterns of lumbar nerve root distribution in this group were examined using magnetic resonance imaging. The relationship between these patterns and the presence of spinal stenosis or previous surgery was investigated. Chronic adhesive arachnoiditic nerve root patterns were seen in 68 patients and were classified into three groups according to Delemarter et al. Central clumping of nerve roots (type 1) and complete opacification of the thecal sac (type 3), extending over at least one vertebral level, were significantly related to spinal stenosis at an adjacent level (p < 0.0001). Peripheral adhesion of nerve roots to the theca (type 2) was significantly related to previous surgery at the level of abnormality (p < 0.00005). Only a single case of arachnoiditic nerve root patterns was seen in the absence of stenosis or previous surgery. We conclude that chronic adhesive arachnoiditis is significantly related to previous Myodil myelography in the presence of spinal stenosis or previous surgery but that Myodil alone rarely produces these changes.

Sparganosis in the spinal canal with partial block: an uncommon infection.

A case of rare intraspinal sparganosis treated by surgical excision is described. In this 59-year-old male with paraparesis and voiding problem, an intradural mass was noted on myelogram. Magnetic resonance (MR) and computed tomographic appearance of spinal and associated cerebral lesion are illustrated and possible route of migration discussed. This represents, to our knowledge, the first MRI demonstration of intraspinal sparganosis reported in the literature.
