Third Nerve Palsy With Complete External Dysfunction And Pupillary Preservation, As A Manifestation Of Aneurysm. Case Report. Rev Ecuat Neurol [online]. 2020, vol.29, n.1, pp.145-148. ISSN 2631-2581.

Acquired paralysis of the oculomotor nerve in the adult population includes various etiologies and frequently those that produce compressive lesions, such as intracranial aneurysms, generate pupillary involvement.

Increasing reports have shown atypical clinical presentations in intracranial aneurysms and this report presents the case of a patient without internal dysfunction or with pupillary preservation in addition to complete external dysfunction, that is, paralysis of all extraocular muscles innervated by the third cranial nerve, due to an intracranial aneurysm, which has not been published in the literature so far. Considering the mortality that is implied by an aneurysmal rupture and the novel clinical presentations reported to date, it is of great importance to request diagnostic means quickly to all patients with third cranial nerve palsy, regardless of their clinical expression.
