Summary
Magnetic Resonance (MR) imaging reveals diverse abnormalities in spinal arachnoiditis caused by tuberculosis. This imaging modality is crucial for diagnosing spinal tuberculosis and its complications.
Area of Science:
- Neurology
- Radiology
- Infectious Diseases
Background:
- Spinal arachnoiditis is a serious complication of tuberculosis.
- Accurate diagnosis is essential for effective management.
Purpose of the Study:
- To investigate the range of abnormalities identified by MR imaging in patients diagnosed with tubercular spinal arachnoiditis.
Main Methods:
- A retrospective analysis was conducted on the MR imaging findings of 22 patients with confirmed tubercular spinal arachnoiditis.
- Diagnosis was confirmed through clinical presentation, cerebrospinal fluid (CSF) analysis, and evidence of associated tuberculosis.
Main Results:
- MR imaging demonstrated multi-segmental spinal involvement in 86% of patients, predominantly in the dorsal region.
- Abnormalities included increased T1 and T2 signal intensity in the CSF and spinal cord, cord cavitation, CSF loculations, subarachnoid nodules, and cauda equina nerve root clumping.
- Contrast-enhanced MR imaging revealed meningeal and nerve root enhancement in a significant proportion of patients, with some showing cord enhancement.
Conclusions:
- MR imaging effectively visualizes the pathological changes associated with tubercular spinal arachnoiditis.
- The findings suggest MR imaging plays a vital role in diagnosing this condition.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
