Summary
En plaque meningiomas, rare tumors in the spheno-orbital region, present unique challenges. Optimal treatment requires an individualized approach, balancing aggressive resection with emerging therapies for these complex meningiomas.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- En plaque meningiomas are rare, invasive tumors often found in the spheno-orbital region.
- They are characterized by hyperostosis and dural invasion, posing diagnostic and therapeutic challenges.
Purpose of the Study:
- To review the literature on en plaque meningiomas, covering epidemiology, clinical presentation, diagnosis, and treatment.
- To present a case study illustrating the complexity of these tumors.
Main Methods:
- A narrative literature review was performed using MEDLINE.
- Search terms included 'meningioma', 'en plaque', 'skull base', 'spheno-orbital', and 'sphenoid wing'.
- English-language literature from 1938-2018 was analyzed, focusing on treatment outcomes and misdiagnosed cases.
Main Results:
- En plaque meningiomas exhibit varied symptoms based on location and bone invasion.
- Diagnosis and treatment require careful consideration.
- Early, aggressive surgical resection is often considered optimal, but individualized approaches are necessary.
Conclusions:
- En plaque meningiomas necessitate tailored diagnostic and treatment strategies.
- Further research is needed on the role of novel therapies in managing these lesions.

2.4K
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...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
