Summary
A rare primary ectopic meningioma in the ethmoid sinus was successfully removed via rhinotomy. Magnetic resonance imaging (MRI) was crucial for diagnosis and surgical planning, leading to a good patient outcome.
Area of Science:
- Neuro-oncology
- Otorhinolaryngology
- Neurosurgery
Background:
- Primary ectopic meningiomas are rare tumors that can occur outside the central nervous system.
- Meningiomas in the sinonasal region, particularly the ethmoid sinus, are uncommon and can present diagnostic challenges.
Observation:
- A case report details a 29-year-old female diagnosed with a primary ectopic meningioma in the right ethmoid sinus.
- The tumor presented as a well-circumscribed mass with significant homogeneous contrast enhancement on MRI.
Findings:
- Surgical intervention using a right lateral rhinotomy approach resulted in the total removal of the ethmoid sinus tumor.
- Post-operative follow-up indicated a favorable clinical course for the patient.
Implications:
- This case highlights the importance of advanced imaging, such as contrast-enhanced MRI, in the precise diagnosis and surgical management of sinonasal tumors.
- Successful surgical resection of ectopic meningiomas can lead to excellent patient outcomes, even in challenging locations like the ethmoid sinus.

01:27Cranial Bones: Lateral View
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...

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
