Tuberculous spinal arachnoditis, a common cause of paraplegia in India, presents diagnostic challenges. Myelography and CT myelography reveal characteristic radiological features aiding in diagnosis.
Area of Science:
- Neurology
- Radiology
- Infectious Diseases
Background:
- Tuberculous spinal arachnoditis is a frequent cause of paraplegia in India.
- Accurate clinical and laboratory diagnosis is often challenging.
Purpose of the Study:
- To describe the diagnostic role of radiological evaluations in tuberculous spinal arachnoditis.
- To outline the characteristic findings on myelography and CT myelography.
Main Methods:
- Review of myelography with water-soluble contrast medium.
- Analysis of computed tomography (CT) features.
- Correlation of radiological findings with clinical presentation.
Main Results:
- Common myelographic findings include irregular contrast, nodular defects, thickened nerve roots, and empty thecal sac.
- CT features include irregular subarachnoid contrast and extradural/intradural filling defects.
- Nerve root adherence to meninges was frequently observed.
Conclusions:
- Myelography and CT myelography demonstrate characteristic features suggestive of tuberculous spinal arachnoditis.
- Radiological evaluation is crucial for diagnosis and management of this condition.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

The Role of Ion Channels in Neuronal Computation
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....
