title: Syndromal hypothalamic hamartoblastoma with holoprosencephaly sequence, microphthalmia, pulmonary malformations, radial hypoplasia and müllerian regression: further delineation of a new syndrome?
abstract: A 24-week-old fetus is described here with holoprosencephaly sequence (arhinencephaly and agenesis of the corpus callosum) associated with brain and meningeal dysplasia, microphthalmia with an ectopic pigmentary layer, hypothalamic hamartoblastoma, preaxial asymmetric limb reduction, lung hypoplasia, gastric hypoplasia, Müllerian regression, intestinal malrotation, asplenia, and normal chromosomes. The differential diagnosis includes the Cerebroacrovisceral-Early lethality (CAVE) phenotype, and the Pallister-Hall syndrome, but the anomalies best fit the severe form of microgastria-limb reduction syndrome. Together with a previous case reported by Meinecke, the pattern of anomalies appears to represent a combination of defects, related to but distinct from the microgastria-limb reduction syndrome.
