Abstract:Pontine tegmental cap dysplasia is a rare hindbrain malformation syndrome with a hypoplastic pons, a tissue protrusion into the fourth ventricle, and cranial nerve dysfunction. We here report clinical, imaging, and genetic findings of the first extremely low-birth-weight preterm infant with pontine tegmental cap dysplasia born at 25 weeks of gestation and provide an overview of 29 sporadic cases. A prenatally diagnosed hypoplastic and rostrally shifted cerebellum was indicative of a hindbrain defect and later identified as an early sign of pontine tegmental cap dysplasia in our patient. The neonate exhibited severe muscle hypotonia, persistent thermolability, and clinical signs of an involvement of facial, cochlear, and hypoglossal nerves. Furthermore, paroxysmal episodes of agonizing pain with facial tics, tonic and clonic muscle contractions, blepharospasm, and singultus are highlighted as new phenotypic features of pontine tegmental cap dysplasia. With our report, we present a severe case of pontine tegmental cap dysplasia and provide a brief overview of current knowledge on this rare disease.
