This case highlights a unique pattern of neoplasm development along a dermatome, an area of skin where innervation derives from a single spinal nerve. Symptoms that follow a dermatome often point to a pathology involving the related nerve root.
CMT 1A is characterized by progressive weakness and atrophy of the distal limb muscles beginning in the peroneal group, mild distal sensory loss, diminished tendon reflexes, and slow nerve conduction velocity.[1] Spinal nerve root hypertrophy is a distinct sign of CMT 1A.[2] This sign can be detected on magnetic resonance images (MRI), but it is often overlooked.
The guidelines apply to non-radicular pain--that is, pain not stemming from damage to the spinal nerve root.
