Novel presentation of acalvaria with clavicular absence: A case report.

Rationale: Acalvaria is an exceptionally rare congenital disorder marked by the absence of flat bones of the cranial vault, dura mater, and associated muscles, while the facial bones and base of the skull remain intact. Typically, the central nervous system is unaffected. Due to their extreme rarity, reported cases in the literature are infrequent.
