Massive pericardial effusion in an infant with Aymé-Gripp syndrome: A case report and review of the literature.

Aymé-Gripp syndrome (AYGRPS) is a multisystemic disorder caused by a subset of pathogenic variants in the MAF gene. Major clinical features include bilateral early cataracts, sensorineural hearing loss (SNHL), and a characteristic facial appearance along with variable neurodevelopmental delay. Pericarditis resulting in pericardial effusion of varying degree has been observed in a subset of affected individuals and could represent a severe feature in neonatal or infantile age. Here, we describe a syndromic infant with massive pericardial effusion and craniofacial features that oriented toward the suspicion of AYGRPS, which was subsequently confirmed by the molecular analysis of MAF. Pericardial effusion was first observed prenatally and documented to be recurrent, progressive, and severe in the first months of life, thus requiring pericardiocentesis and surgical procedures. In this report, we provide further delineation of the minor clinical characteristics, particularly focusing on cardiac features of AYGRPS. A dedicated cardiac surveillance of these findings may help reduce the morbidity and mortality of this rare condition.
