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]
