Abstract

BACKGROUND: Inclusion-body myopathy with Paget's disease of the bone and frontotemporal dementia (IBMPFD) is a rare, late-onset autosomal disorder arising from missense mutations in a gene coding for valosin-containing protein.

CASE REPORT: We report the case of a man carrying the previously described p.Arg159His mutation, who had an unusual axonal sensorimotor neuropathy as the first clinical manifestation of IBMPFD, and for whom diagnosis only became clear 8 years later when the patient developed frontotemporal dementia.

CONCLUSIONS: Peripheral neuropathy is a rare manifestation of IBMPFD. This underdiagnosed disorder should be considered when a patient develops dementia or has signs of Paget's disease.

Keywords: IBMPFD; Paget's disease; frontotemporal dementia; sensorimotor neuropathy; valosin-containing protein
