Abstract

Insights

Primary pulmonary meningioma (PPM) is a rare lung tumor. Surgical resection, like wedge resection, is the optimal treatment for this condition, offering a good prognosis for most patients.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Oncology

Background:

  • Primary pulmonary meningioma (PPM) is an exceptionally rare neoplasm, with fewer than 60 cases documented globally.
  • The exact origins and development pathways of PPM remain largely unknown.
  • This report details a case of PPM and reviews existing literature to elucidate its characteristics.

Observation:

  • A 57-year-old male presented with a growing right middle lobe pulmonary nodule, initially detected over seven years prior.
  • Imaging revealed significant growth of the subpleural nodule.
  • The patient underwent successful thoracoscopic right middle lobe wedge resection.

Findings:

  • Pathological diagnosis confirmed primary pulmonary meningioma.
  • Post-operative follow-up showed no signs of recurrence.
  • PPM often presents as a solitary ground-glass nodule, mimicking lung cancer, and can involve multiple lobes or the pleura.

Implications:

  • Surgical intervention is the gold standard for both diagnosing and treating PPM.
  • Wedge resection is typically sufficient for benign PPM, ensuring a favorable prognosis.
  • Malignant PPM cases may necessitate more extensive surgery (lobectomy) and adjuvant therapies like radiotherapy and chemotherapy.

Viral Meningitis01:18

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 Meningitis01:27

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: Introduction01:22

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: Pathophysiology01:26

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: Introduction01:26

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,...
