An atypical chronic inflammatory demyelinating polyradiculoneuropathy that radiologically mimicking neurofibromatosis: Case report

38137

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an uncommon demyelinating disorder with a relapsing and remitting or continuously progressive course. Patients may have motor and sensory involvement, but generally motor involvement may be more prominent and more severe in lower extremities. CIDP is a treatable neuropathy that is challenging to diagnose and has a broad spectrum of presentations. When ranked by the descending frequency, postural tremor in the arms, peripheral nerve thickening, papilledema and facial or bulbar weakness, respiratory failure and autonomic dysfunction can be seen in patients with CIDP. Demyelinating neuropathy predominantly affects spinal roots, plexuses and proximal nerve trunks and thickened nerves can be palpable in about 10% of the patients. In patients with atypical presentation, the diagnosis of CIDP may be delayed and hypertrophic nerve roots have been reported in CIDP patients with delayed diagnosis. Magnetic Resonance Imaging (MRI) may be helpful in the diagnosis of CIDP by excluding the compressive or structural lesions that may lead to polyradiculopathy and MRI may also show hypertrophy of nerve roots and inflammatory processes in CIDP. We presented a patient with CIDP who had MRI findings of diffuse enlargement and mild enhancement of roots and extraforaminal segments of nerves in all segments.
