The purpose of this poster is to describe: the anatomy of the third cranial - oculomotor nerve (CNIII) clinical signs and symptoms of CNIII palsy, imaging modalities and characteristic findings in patients with this clinical presentation, and underline the importance of adequate clinical data w[...]
Anatomy and pathology by segments of the CNIII CNIII or the oculomotor nerve has two components - somatic component contains motor nerve fibers that control most of the extra ocular muscles (inferior, superior, medial rectus, inferior oblique and the levator palpebrae superioris muscle). Visceral [...]
Findings and procedure details:
Clinical syndromes CNII palsy can be either isolated, that is, only the function of CNIII is affected, or nonisolated – there are additional clinical signs and symptoms present. Especially in case of isolated CNIII palsy, a distinction between partial and complete nerve involvement should be made.[...]
Detailed clinical background combined with the understanding of different patterns of signs and symptoms and knowledge of site specific pathology enables the radiologist to make a precise imaging diagnosis.
