Summary
A rare case of cortical subarachnoid hemorrhage (cSAH) linked to Behcet's disease is presented. The study details a non-mycotic aneurysm that spontaneously resolved after diagnostic angiography, highlighting potential long-term vascular complications.
Area of Science:
- Neurology
- Vascular Surgery
- Rheumatology
Background:
- Cortical subarachnoid hemorrhage (cSAH) presents diverse etiologies.
- Behcet's disease is a systemic vasculitis with rare neurological manifestations.
Observation:
- A 58-year-old male with Behcet's disease presented with sudden headache.
- Computed tomography revealed cSAH in the left frontal sulci.
- A ruptured middle cerebral artery cortical branch aneurysm was identified.
Findings:
- The identified aneurysm spontaneously obliterated after diagnostic cerebral angiography.
- This represents a rare instance of non-mycotic distal cerebral artery aneurysm causing cSAH.
- The aneurysm's resolution post-angiography is an unusual finding.
Implications:
- Non-mycotic distal cerebral artery aneurysms are a rare cause of cSAH.
- Spontaneous obliteration of distal dissecting aneurysms after angiography is uncommon.
- Such aneurysms may represent a long-term vascular complication of Behcet's disease.

01:25Glaucoma: Overview
945
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:28Angle Closure Glaucoma: Treatment
870
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
