Summary
A rare calvarial meningioma with extensive bone changes and frontal sinusitis was diagnosed and surgically removed in a 40-year-old female. This case highlights the importance of considering meningiomas in the differential diagnosis of complex frontal sinus lesions.
Area of Science:
- Neurosurgery
- Otolaryngology
- Radiology
Background:
- Primary extradural meningiomas are rare tumors.
- Calvarial meningiomas with extensive bony changes and frontal sinusitis are exceptionally rare presentations.
Purpose of the Study:
- To report a rare case of calvarial meningioma presenting as frontal sinusitis.
- To discuss the radiological differential diagnosis and management of such lesions.
Main Methods:
- Case report of a 40-year-old female patient.
- Clinical examination and imaging (computed tomography).
- Surgical resection via left frontal craniotomy.
Main Results:
- Diagnosis of a left frontal calvarial meningioma with extensive bony changes and extracalvarial extension into the frontal sinus.
- Successful tumor removal with an uneventful postoperative period.
- Follow-up imaging confirmed postoperative changes without residual tumor.
Conclusions:
- Calvarial meningiomas can present with complex radiological features mimicking other conditions like sinusitis and osteomyelitis.
- Multidisciplinary approach is crucial for accurate diagnosis and management.
- Surgical excision is an effective treatment for symptomatic calvarial meningiomas.

01:26Brain Abscess l: Introduction
6
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...

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...

01:26Bacterial Meningitis II: Pathophysiology
3
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
