31467002: Base of skull structure (body structure)

SNOMED CT Concept\Body structure (body structure)\Anatomical or acquired body structure (body structure)\Anatomical structure\...

\An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Structure of bone organ\Bone structure\Regional bone structure\Bone structure of head and/or neck (body structure)\Bone structure of head\Bone structure of cranium\Bone structure of neurocranium\Base of skull structure

\Body system structure\Structure of musculoskeletal system (body structure)\...

A rare primary bone dysplasia with increased bone density characterized by slowly progressive endosteal hyperostosis and osteosclerosis exclusively of the skull base and the calvaria, resulting in entrapment and dysfunction of cranial nerves I, II, V, VII, and VIII. First symptoms often appear during the second decade of life and include disturbances in smell, vision, facial sensation and expression, hearing, and balance, as well as headaches due to increased ocular and intracranial pressure. After the fourth decade, radiological progression is minimal, although decreased intracranial volume can lead to death in severe cases.
