%X <B>BACKGROUND: </B>Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common acquired immune-mediated inflammatory disorder of the peripheral nervous system. The diagnosis is based mainly on the clinical presentation and electrophysiological detection of demyelination.<BR><B>METHODS: </B>Several MRI studies have demonstrated hypertrophy and abnormal enhancement of spinal nerve roots or brachial plexus in CIDP, but there have been only anecdotal reports of similar sonographic findings.<BR><B>RESULTS: </B>This article reports the sonographic findings of a CIDP case and includes a review of the literature and previously reported cases.<BR><B>CONCLUSIONS: </B>This case report highlights the importance of sonography in the localization and recognition of focal nerve enlargements in patients with CIDP. This method could be a helpful tool in the diagnosis of conduction block in CIDP, especially in cases where a nerve segment cannot be explored easily with the inching technique. Systematic data are needed to confirm this observation.
