Primary cerebellopontine angle angiosarcoma
1Department of Neurosurgery, Shandong Provincial Hospital Shandong University, Jinan 250021, People's Republic of China.
Summary
Primary intracranial angiosarcomas are rare, with no prior reports in the cerebellopontine (CP) angle. This case details a successful surgical removal and radiotherapy for a CP angle angiosarcoma in a young patient, highlighting its potential presentation.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Primary intracranial angiosarcomas are exceptionally rare neoplasms.
- Previous reports have exclusively documented supratentorial locations.
Observation:
- A 16-year-old female presented with a year of mild headache, tinnitus, and hearing loss, followed by acute severe headache, vomiting, left hemiparesis, ataxia, and numbness.
- Imaging revealed a right cerebellopontine (CP) angle lesion with hemorrhage and edema, initially suspected as a neurogenic tumor.
Findings:
- Surgical excision and histopathological analysis confirmed the lesion as an angiosarcoma.
- The patient received postoperative radiotherapy and showed significant clinical improvement.
Implications:
- This case represents the first reported instance of an angiosarcoma in the cerebellopontine (CP) angle.
- It underscores the importance of considering angiosarcoma in the differential diagnosis of rare CP angle masses.
- Awareness of angiosarcoma's characteristics is crucial for accurate diagnosis and management of rare intracranial tumors.

Angle 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...
Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Glaucoma: Overview
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...
