Duplication of the pituitary gland is a rare midline cerebral malformation disorder characterized by duplicated pituitary stalks and/or glands within duplicated sella. Patients may present various degrees of facial dysmorphism and endocrine abnormalities, including precocious puberty, hypogonadism, hypothyroidism and/or hyperprolactinemia, as well as associated congenital anomalies, such as clift lip/palate, bifid nasal bridge/tongue/uvula, hypothalamic enlargement with or without hamartoma, nasopharyngeal tumors, corpus callosum agenesis/hypoplasia, basilar artery duplication, and/or vertebral defects (in particular, duplication of the odontoid process).

Cleft palate is a developmental defect of the palate resulting from a failure of fusion of the palatine processes and manifesting as a separation of the roof of the mouth (soft and hard palate).
