Platybasia

Platybasia is a spinal disease of a malformed relationship between the occipital bone and cervical spine. It may be caused by Paget's disease. Platybasia is also a feature of Gorlin-Goltz syndrome, commonly known as basal cell nevus syndrome About Platybasia. Platybasia is an abnormality of the base of the skull, literally flattening of the skull base. It may be developmental in origin or due to softening of the skull base bone, allowing it to be pushed upward (see Basilar Invagination ). The developmental variant is the result of a wider (flatter) angle between the skull base of the.

Platybasia is abnormal flattening of the skull base. Platybasia can occur in a variety of congenital disorders (e.g., craniofacial anomalies, osteogenesis imperfecta, craniocleidodysostosis, Arnold-Chiari malformation) or in acquired diseases (e.g., Paget disease, osteomalacia, rickets, trauma) ( 1 , 2 ) Platybasia (Basilar Impression): Read more about Symptoms, Diagnosis, Treatment, Complications, Causes and Prognosis

Basilar impression (platybasia): a bizarre developmental anomaly of the occipital bone and upper cervical spine with striking and misleading neurologic manifestations The congenital and acquired deformities of the craniovertebral junction (CVJ), such as basilar invagination, basilar impression, or platybasia, can present in the form of slowly progressive or acute neurologic deterioration. In many cases, an insidious headache is the only symptom and can be a diagnostic challenge for the neurologist Platybasia, an abnormal shallowness of the base of the skull, is a malformation that may be associated with projection of the vertebral column upward. This condition may also occur in association with bone diseases such as osteomalacia and Paget disease of bone in adulthood Strictly speaking, platybasia is an anthropological term referring to a flattening of the clivus in respect to the skull, while basilar impression refers to a protrusion of the base of the skull into the posterior fossa; but the names are used interchangeably for the clinical anomaly here described Platybasia . Platybasia refers to an increase in the Welcher basal angle ( Figs. 8 and 9 ). Platybasia alone does not usually cause symptoms unless it is associated with basilar invagination
