Dandy-Walker Variant Associated with Bilateral Congenital Cataract

Dandy-Walker Syndrome (D-WS) is a rare disorder with an incidence of 1%-2% of all central nervous system anomalies. The diagnosis can be challenging, especially in the prenatal period. Here, we present an extremely rare case of D-WS associated with bilateral congenital cataracts. A 36 weeks and 6 days old male baby presented with a Dandy-Walker variant associated with bilateral congenital cataract. Ophthalmological examination revealed microphthalmos and congenital cataracts present in both eyes with sclerocornea, iris coloboma, and zone 3 retinopathy of prematurity involving only the right eye. However, the right eye was salvageable. Skull transillumination was negative with no cranial bruit. He was admitted to the neonatal intensive care unit with breathing difficulties, maintained SpO₂ with oxygen through prongs, and noninvasive continuous positive airway pressure for 7 days. He had two episodes of hypoglycemia with hypothermia. There was no significant finding in sepsis evaluation. The abdominal ultrasonography was normal. Echocardiogram was suggestive of patent foramen ovale. Mother's torch panel tested positive for cytomegalovirus immunoglobulin G antibodies. Magnetic resonance imaging brain suggested variant D-WS with dilation of cerebellar fossa and occipital lateral ventricle horn and lack of usual corpus callus structure. Intravenous antibiotics cefotaxime and amikacin were administered along with fluid supplementation. He was shifted to mother feed. The neonate was referred to the pediatric surgery department for further management.
