Progressive ponto-bulbar palsy with deafness. A clinico-pathological study

Area of Science:

• Neurology
• Genetics
• Pathology

Background:

• Progressive ponto-bulbar palsy with deafness (PPPD) is a rare, likely abiotrophic neurological disorder.
• Autosomal recessive inheritance is suggested, with limited prior pathological descriptions.

Observation:

• This report details the clinical and pathological findings of a novel case of PPPD.
• The case involved significant involvement of the brain stem and spinal cord grey matter.

Findings:

• Pathological examination revealed widespread lesions in the brain stem and spinal cord.
• Optic tracts and most brain stem fiber tracts were affected, excluding the pyramidal tracts.

Implications:

• This case expands the understanding of PPPD's pathological spectrum.
• Further research into the genetic and molecular basis of PPPD is warranted.
