Summary
This case report details a rare instance of orbital ependymoma, a brain tumor extending into the eye socket. The patient experienced vision loss and double vision due to this unusual tumor extension.
Area of Science:
- Neuro-oncology
- Ophthalmology
- Neurosurgery
Background:
- Orbital ependymomas are exceptionally rare, often arising from intracranial tumors.
- Intraventricular ependymomas can extend extracranially, leading to orbital involvement.

Cranial and Spinal Meninges
1.9K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Cranial Bones: Lateral View
3.1K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
