Neurological Causes of Band-Like Sensation

Primary Demyelinating Disorders

Balo's concentric sclerosis is characterized by band-like enhancement on MRI imaging, which is a "red flag" finding that should prompt consideration of diagnoses beyond typical MS 1, 2
Neuromyelitis optica spectrum disorders (NMOSD) can cause longitudinally extensive transverse myelitis, producing band-like sensory symptoms, and cloud-like enhancement patterns on MRI help differentiate NMOSD from MS 2, 3

Inflammatory lesions of the spinal cord produce dermatomal sensory levels manifesting as band-like sensations at the level of cord involvement, corresponding to the upper border of sensory loss and representing partial cord dysfunction 3
Cervical spondylosis with cord compression can produce the "pancake sign" on MRI and cause band-like sensations from mechanical compression, and structural lesions including tumors, herniated discs, or spinal stenosis may present similarly 2, 3, 4

Diabetic peripheral neuropathy typically presents as distal symmetric polyneuropathy with "stocking-glove" distribution rather than true band-like sensations, but truncal radiculopathy in diabetes can produce band-like pain around the chest or abdomen 5
Late neurologic Lyme disease can cause peripheral neuropathy with radicular pain and intermittent limb paresthesias, typically manifesting as confluent mononeuritis multiplex rather than discrete band-like sensations 4

New band-like sensation with progressive weakness, bowel/bladder dysfunction, or gait disturbance mandates urgent spinal cord imaging to exclude compressive myelopathy or acute transverse myelitis 3
Band-like enhancement on MRI should prompt consideration of atypical demyelinating disorders including Balo's disease or NMOSD 1, 2
True band-like sensations at a specific dermatomal level indicate spinal cord pathology rather than peripheral nerve disease, and associated neurological signs including hyperreflexia, Babinski sign, or sensory level confirm central (spinal cord) localization 3
