kleeblattschädel
Pronunciation: KLAY-blat-shay-del
A severe skull deformity resembling a cloverleaf, caused by multiple suture fusions.
Full Definition
Kleeblattschädel, German for 'cloverleaf skull,' is a rare and severe cranial deformity characterized by a trilobar skull shape resembling a cloverleaf when viewed from above. This condition results from premature fusion of multiple cranial sutures, typically the coronal and lambdoid sutures, with the sagittal suture remaining open. The deformity creates three distinct bulges: frontal, temporal, and occipital, separated by deep grooves. Kleeblattschädel is associated with severe increased intracranial pressure and hydrocephalus, requiring immediate neurosurgical intervention. The condition may occur in isolation or as part of syndromic craniosynostosis, particularly Pfeiffer syndrome type 2. Multiple staged surgical procedures are typically required for management.
Usage
Usage note: German term; may be anglicized as 'cloverleaf skull' in patient documentation.
