title: Localized hypertrophic mononeuropathy involving spinal roots and associated with sacral meningocele. Case report.
abstract: Hypertrophic nerve lesions displaying onion-bulb cellular formations are quite rare in the absence of a generalized hypertrophic neuropathy. The isolated peripheral nerve lesion has been termed "localized hypertrophic mononeuropathy" (LHN), and fewer than 30 cases of this condition have been reported. Very little is known regarding the etiology and the natural course of this rare disorder. A unique case of LHN afflicting spinal roots in association with a sacral meningocele is reported with a brief review of the relevant literature. The unique features of this case not only reveal a variable clinical presentation of the disease but also support the theory that LHN may be a localized reaction to nerve trauma or entrapment.
