Pontine Tegmental Cap Dysplasia Presenting With Global Developmental Delay and Vestibulocochlear Nerve Aplasia: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT PTCD should be considered in children with developmental delay and sensorineural hearing loss. MRI is crucial for identifying the characteristic dorsal “tegmental cap” and associated hindbrain anomalies. Vestibulocochlear nerve aplasia may explain severe hearing impairment in PTCD.
