Cri-du-chat syndrome (CdCS) is a rare genetic disorder in which the short arm of chromosome 5 is deleted. This report aims to highlight a rare association with the syndrome. We present a preterm male delivered at 35 weeks gestation with an antenatal diagnosis of meningomyelocele. The patient's clinical examination revealed ruptured lumbosacral meningomyelocele, lower limb hypotonia, and hyporeflexia. The patient also displayed dysmorphic features, including microcephaly, a rounded face, low-set ears, and club feet. In addition, he is noted to have a high-pitched cry. Diagnosis of Chiari tonsil hernia type II was made by magnetic resonance imaging, and whole exome sequencing has confirmed CdCS. The spina bifida was surgically corrected, and the patient has since been cared for by a multidisciplinary team. The patient's short-term follow-up revealed a significant developmental delay. Few cases of CdCS associated with meningomyelocele have been reported. More evidence is needed to support a relevant association between CdCS and meningomyelocele.
