ICD-10: Q75.051

Clinical Description of Cloverleaf Skull (ICD-10 Code Q75.051)

Cloverleaf skull, also known as Kleeblattschädel, is a rare craniosynostosis condition characterized by a distinctive skull shape that resembles a cloverleaf. This condition arises from the premature fusion of multiple cranial sutures, leading to abnormal skull development. The term "cloverleaf" refers to the appearance of the skull, which has a prominent forehead, a flattened occiput, and bulging sides, creating a three-lobed shape.

Etiology and Pathophysiology

Cloverleaf skull is often associated with various syndromes, including Crouzon syndrome, Apert syndrome, and Pfeiffer syndrome. The exact cause of cloverleaf skull is not fully understood, but it is believed to involve genetic factors that affect the normal development of cranial sutures. The condition can lead to increased intracranial pressure due to restricted brain growth, which may result in neurological complications.

Clinical Features

Patients with cloverleaf skull may present with several clinical features, including:

• Distinctive Skull Shape: The most notable feature is the cloverleaf appearance of the skull, which is caused by the fusion of the coronal, sagittal, and lambdoid sutures.
• Facial Abnormalities: Individuals may exhibit facial dysmorphism, including hypertelorism (widely spaced eyes), a beaked nose, and a prominent forehead.
• Neurological Issues: Due to increased intracranial pressure, patients may experience developmental delays, cognitive impairments, and other neurological deficits.
• Hearing Loss: Conductive hearing loss is common due to middle ear abnormalities associated with craniofacial syndromes.

Diagnosis

Diagnosis of cloverleaf skull typically involves:

• Clinical Examination: A thorough physical examination to assess the skull shape and associated features.
