Viral Meningitis

Viral Meningitis

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...

Cryptococcal Meningitis

Cryptococcal 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,...

Bacterial Meningitis I: Introduction

Bacterial 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...

Bacterial Meningitis II: Pathophysiology

Bacterial Meningitis II: Pathophysiology

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...

Brain Abscess l: Introduction

Brain 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,...

Area of Science:

Oncology
Pathology
Thoracic Surgery

Background:

Primary meningiomas are uncommon outside the head and neck, with extracranial occurrences being rare.
This case report focuses on a primary pulmonary meningioma, a distinct entity within thoracic oncology.

Observation:

A 44-year-old female presented with a year of chest pain, found to have a 1.8 cm right lower lobe pulmonary nodule on CT scan.
Histopathological examination revealed a tumor with whorled spindle-shaped cells and psammoma bodies, consistent with meningioma.

Findings:

Immunohistochemistry confirmed positivity for vimentin and S-100, supporting the diagnosis of pulmonary meningioma.
The patient underwent successful thoracoscopic pulmonary wedge resection.
Postoperative imaging showed no evidence of intracranial or spinal meningioma, and no recurrence was noted.

Implications:

Pulmonary meningioma, though rare, should be included in the differential diagnosis for pulmonary nodules.
This case underscores the importance of comprehensive histopathological and immunohistochemical evaluation for accurate diagnosis and management of lung tumors.
