In this study the cranial nerves development of H. huso are explained from 1 to 54-days-old (1, 3, 6, 15, 21 and 54 days). Despite all the researches on fish brain, there are no study on nerves evolution on H. huso during their larvae life. For this research 40 samples of larvae H. husowere obtained (from each age, about six samples were selected). The specimens were ...

A 40-year-old man developed headache and a left oculomotor nerve palsy. MRI revealed diffuse enlargement of the pituitary gland and thickening of the pituitary stalk with strong gadolinium enhancement (figure). CSF examination showed a lymphocytic pleocytosis; there were laboratory findings of panhypopituitarism, but no related symptoms. We administered IV methylprednisolone. The headache and o...

Oculomotor nerve palsy (ONP) due to internal carotid-posterior communicating artery (PcomA) aneurysm generally manifests as partial nerve palsy including pupillary dysfunction. In contrast, infundibular dilatation (ID) of the PcomA has no pathogenic significance, and mechanical compression of the cranial nerve is extremely rare. We describe a 60-year-old woman who presented with progressive pto...

INTRODUCTION Bilateral third nerve palsy secondary to a hemorrhagic stroke is exceptional. To the best of our knowledge, no similar case has been reported in the literature. CASE PRESENTATION We describe the case of a 69-year-old Moroccan man who presented with isolated sudden bilateral third nerve palsy. Computed tomography (CT) of the brain revealed a midbrain hematoma. The oculomotor funct...

Three patients had oculomotor nerve palsy as a complication of the treatment of carotid cavernous fistulae by electrometallicthrombosis of the cavernous sinus. In two, third nerve function returned without misdirection in two months or less. One was left with a partial third nerve palsy, also without misdirection.

Third nerve palsy is an uncommon condition that carries significant risk of serious disease due to both the variability of its presentation and its association with intracranial aneurysms. In this article, we review the existing literature on the pathophysiology, diagnosis, and management of third nerve palsy presenting to the Emergency Department.
