Introduction Orbital meningoencephalocele formation is primarily a result of congenital defects in the pediatric population and trauma of the anterior cranial fossa in adults. We present a unique case of nontraumatic nasal and orbital meningoencephaloceles presenting as bilateral proptosis with exotropia secondary to chronic hydrocephalus. Clinical presentation A 20-year-old male with a history of tuberous sclerosis, X-linked intellectual disability, and epilepsy presented to the emergency department with two days of nausea, emesis, seizures, and two months of progressive proptosis. Initial radiographs of the skull showed a "copper beaten" appearance, indicating chronically elevated intracranial pressure. Computed tomography imaging of the head demonstrated bilateral defects in the cribriform plate and anterior cranial fossa. Magnetic resonance imaging of the brain revealed triventricular hydrocephalus with meningoencephalocele extension into the nasal cavity and frontal horn herniation into the extraconal space of the orbits. The hydrocephalus was managed with ventriculoperitoneal shunt placement with rapid and complete resolution of the proptosis. Conclusion No reports have described bilateral proptosis as the presenting finding of orbital and nasal meningoencephaloceles in the absence of trauma or congenital defect. This case study demonstrates the management of meningoencephalocele formation secondary to chronic hydrocephalus.

Giant aneurysm of the intracranial carotid artery is a relatively rare disorder which can lead to life-threatening consequences. Ophthalmologic symptoms, mainly oculomotor nerve palsies, usually reveal lesions of the cavernous sinuses. We report the case of a 39-year old female patient presenting with rapidly progressive unilateral exophthalmos (A, B) and binocular diplopia associated with headaches affect one half of the head causing a single episode of vomiting evolving in a context of apyrexia and general state preservation. Ophthalmologic examination showed isolated palsies of the right lateral rectus muscle (abduction deficit). Static and dynamic assessment of the eyelids was normal. Corrected visual acuity was 5/10. Slit lamp exam showed dilation of the conjunctival vessels (C), clear cornea that didn't take up fluorescein, preserved direct and consensual pupillary light reflex, intra-ocular pressure 15 mmhg and venous tortuosities at the back of the eye, without papillary abnormalities (D). Neuroradiological assessment, such as magnetic resonance angiography, showed compressive aneurysms of the intracavernous portion of the right internal carotid artery with grade III exophthalmos. Cerebral angiography objectified right giant ruptured saccular cavernous carotid aneurysm in the cavernous sinuses (E) with anterior and posterior venous drainage associated with aneurysm of the left carotid syphon (F).
