Leptocephaly is a rare form of complex craniosynostosis (usually considered a form of scaphocephaly) in which the sagittal and metopic suture simultaneously close. [1] [2] [3] Leptocephaly is characterized by equal narrowing of the head (from full sagittal fusion) and a tall and narrow (rather than long) head shape. [4] [5] [6] [7] Leptocephaly is usually nonsyndromic, but has been seen in individual cases such as Neu-Laxova syndrome. [8] [9]

The term leptocephaly has also been used (erroneously) to refer to microcephaly. [10]
