But the most important thing about being able to recognise arachnoiditis is to first know the normal distribution of nerve roots in the spinal canal. Microsurgical arachnoidolysis appears to be a straightforward method for stabilizing the progressive symptoms, though the procedure is technically demanding. Deformities along the dorsal aspect of the thoracic spinal cord are occasionally identified on magnetic resonance imaging (MRI), often in patients presenting with myelopathy ( Fig. Professor of Clinical Neurology, Weill Cornell Medical College. She told me that the radiologist saw indications of arachnoiditis on the MRI, but wanted to confirm. Arachnoiditis is a pain disorder caused by the inflammation of the arachnoid, one of the membranes that surround and protect the nerves of the spinal cord. The phenomenon of adhesive arachnoiditis was first described by Quinke in 1893 in a case report. J Neurol Sci. Arachnoiditis. MRI shows CSF loculation and obliteration of the subarachnoid space or irregularly thickened, clumped nerve roots. MRI diagnosis of focal adhesive arachnoiditis is critical to determine the surgical indication. Chart review was performed to assess the cause of arachnoiditis, and imaging was reviewed by two musculoskeletal and three neurology radiologists, blinded to the clinical data and to each other's imaging interpretation. Currently, rectal MRI .

This inflammation can result in the formation of scar tissue and can cause the spinal nerves to stick together and malfunction.

Chart review was performed to assess the cause of arachnoiditis, and imaging was reviewed by two musculoskeletal and three neurology radiologists, blinded to the clinical data and to each other's imaging interpretation. If your doctor has prescribed medication to prevent claustrophobia or if you will require anesthesia to help you tolerate the MRI, or if you have a pacemaker, you will require additional time to prepare for the exam. It revealed multi-level discarthrosis and diffuse thickening of the terminal thecal sac with aggregated nerve roots, likely resulting from previous arachnoiditis. Sagittal T2. It can occur subsequent to a variety of conditions, although it is most commonly a sequela of spinal surgery or the result of intrathecal injection of radiographic dyes and chemicals with neurotoxic preservatives . Magnetic resonance imaging (MRI) and computed tomography demonstrated a flexion-distraction injury at T12-L1 and unstable burst fracture at L1 with posterior fragment displacement and cauda equina compression. Is arachnoiditis serious? One of the central symptoms of this condition is chronic pain. Three resultant morphological patterns have been described on the basis of imaging 5 . Radsource MRI Web Clinic:Arachnoiditis. Drugs & Supplements. MedicineNet. There is no standard test for arachnoiditis, but imaging tests may be used.
