RESUMEN
Cranial nerve palsy is common in pituitary disease and depends on the extension of the lesion into the cavernous sinuses. Bilateral cranial nerve palsy was described in pituitary adenomas with apoplexy and in only one case in hypophysitis. We present a case of a 32-year-old female manifesting with headache, diplopia, bilateral sixth nerve palsy, and hypopituitarism. Magnetic resonance imaging (MRI) revealed symmetric expansion of the pituitary gland, with bilateral cavernous sinus invasion and thickening of the pituitary stalk. Hypophysitis was suspected, and after treatment with IV methylprednisolone boluses, a decrease in the pituitary lesion was observed, with complete remission of sixth nerve palsy in the right eye and partial improvement in the left eye. In this case, we report an infrequent form of presentation of hypophysitis, and highlight that steroids are the first line of treatment.
RESUMEN
BACKGROUND: Attempts at dynamic reconstruction of the upper eyelid either by neurotization or direct muscle replacement have been scarce. Substitution of the levator palpebrae superioris muscle requires the use of extremely small and pliable structures. As a proof of concept/pilot study, we present a consecutive series of patients who underwent blepharoptosis correction using the neurotized omohyoid muscle graft. METHODS: Retrospective analysis of patients receiving a neurotized omohyoid muscle graft for levator palpebralis substitution between January and December 2019. RESULTS: Five patients were operated (2 male, 3 female); median age was 35.5 years. Median palpebral aperture was 0 mm and levator function was< 1 mm in all cases. Median denervation time for the levator muscle was 9 years. All surgeries were uneventful, and no postoperative complications were seen. Twelve months after the procedure, all patients presented with adequate palpebral aperture on activation of the spinal nerve. Median palpebral aperture was 6.5 mm Postoperative electromyography revealed muscle contraction when stimulation was applied to the spinal nerve. CONCLUSION: This study introduces the concept of severe blepharoptosis correction using the omohyoid muscle. We believe that with time and further technical refinements it could become an invaluable tool in eyelid reconstruction surgery.

Traumatic intracranial pial arteriovenous fistulae are infrequent lesions. Their cardinal signs have been related to mass effect and hemorrhage, but their clinical manifestations due to venous retrograde flow into ophthalmic veins has never been described. This phenomenon is usually seen in dural arteriovenous fistula draining to the cavernous sinus or carotid-cavernous sinus fistula.A traumatic intracranial pial arteriovenous fistula arising from the supraclinoid internal carotid artery in a young patient was revealed by aggressive behavior and ophthalmologic manifestations. The endovascular management included the use of coils, stent, and ethylene-vinyl alcohol with transient balloon occlusion of the parent vessel.
