Summary
Trigonal cavernomas, a rare type of intraventricular cavernous angioma, often present with intracranial hypertension. Surgical removal offers an excellent prognosis for these benign lesions.
Area of Science:
- Neuroscience
- Neurosurgery
- Vascular Neurology
Background:
- Intraventricular cavernomas are rare central nervous system vascular malformations.
- Cavernous angiomas located in the trigone of the lateral ventricles are exceptionally uncommon.
Observation:
- A literature review identified 61 intraventricular cavernous angiomas over 30 years.
- Thirteen of these cases were specifically located in the trigone of the lateral ventricles.
Findings:
- Intracranial hypertension was the most frequent presenting symptom (68.9%) in trigonal cavernomas, followed by seizures (18.2%) and hemorrhage (13.1%).
- Unlike intraparenchymal counterparts, intraventricular cavernomas show a trend towards presenting with intracranial hypertension rather than seizures or focal neurological deficits.
Implications:
- Trigonal cavernomas are benign lesions with excellent outcomes following radical excision.
- Intracranial hypertension and hydrocephalus may be the primary clinical manifestations, warranting attention in diagnosis and management.

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
01:28Angle Closure Glaucoma: Treatment
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...
