A 3-month-old-male infant presented with enlargement of head since birth. Clinical and radiological evaluation revealed congenital hydrocephalus, corpus callosum agenesis, prosencephalic cyst, and cranial vault deficiency with supernumerary nostril on the left side. Right ventriculoperitoneal shunt (Chhabra shunt) surgery was performed. The patient did well postoperatively. Parents of the patient have been counseled for repair of supernumerary nostril. Congenital hydrocephalus with corpus callosum agenesis is rare. Furthermore, supernumerary nostril is a very rare anomaly with <40 cases reported in the literature till date. To the best of our knowledge, congenital hydrocephalus, corpus callosum agenesis, prosencephalic cyst, and cranial vault deficiency associated with supernumerary nostril have not been reported till date. We herein briefly review the pertinent literature and describe the embryopathogenesis of this rare association. We propose that this association is a neurocristopathy.
