Early pontocerebellar hypoplasia with vanishing testes: A new syndrome?

We report on a full-term male infant with hypoplastic male genitalia and bilateral impalpable testes noted at birth, who over the following months developed increasing hypotonia, apneic episodes, and seizures resulting in his death at age 24 weeks. During this period regression of penile corporeal tissue was observed. An endocrinological diagnosis of primary hypogonadism was made and cerebral imaging at 19 weeks showed reduced periventricular white matter with marked pontocerebellar hypoplasia (PCH)/atrophy, but a well-developed posterior fossa. We propose that this condition constitutes a new form of severe PCH/atrophy with testicular regression that has onset in the fetal period.
