This report details a rare case of bilateral trigonal meningiomas in a young male. Surgical excision was successful, with no residual tumor found post-operation.
Area of Science:
- Neurology
- Neurosurgery
- Pathology
Background:
- Raised intracranial pressure can indicate serious neurological conditions.
- Bilateral trigonal masses are exceptionally rare in neurosurgical literature.
Purpose of the Study:
- To report the first known case of bilateral trigonal meningiomas.
- To describe the diagnostic and surgical management of this rare condition.
Main Methods:
- Clinical presentation of raised intracranial pressure.
- Diagnostic imaging using CT Scan and MRI of the brain.
- Surgical excision via occipitoparietal transventricular approach.
- Histopathological examination for definitive diagnosis.
Main Results:
- Identified mirror-image mass lesions in the trigone of each lateral ventricle.
- Achieved total excision of both meningiomas.
- Confirmed absence of residual tumor on postoperative CT scans.
- Histopathology confirmed the diagnosis of meningioma.
Conclusions:
- Bilateral trigonal meningiomas are a rare entity.
- Successful surgical management is achievable.
- This case represents the first documented instance of this condition.

Cranial Bones: Lateral View
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...
