Insights

This case report details a rare adult primary meningeal rhabdomyosarcoma, a brain malignancy. The patient received multimodal therapy including surgery, radiotherapy, and chemotherapy.

Area of Science:

  • Neuro-oncology
  • Pathology
  • Radiology

Background:

  • Primary meningeal rhabdomyosarcoma is an exceptionally rare brain malignancy.
  • While typically diagnosed in pediatric patients, adult cases are infrequently documented.

Observation:

  • A 44-year-old male presented with neurological deficits including right lower extremity weakness, word finding difficulty, and headaches.
  • Brain MRI revealed a vertex lesion suggestive of a meningeal tumor.
  • Initial surgical resection was subtotal due to sagittal sinus invasion, with pathology initially misdiagnosed as anaplastic meningioma.

Findings:

  • Pathological re-evaluation confirmed primary meningeal rhabdomyosarcoma, negative for the t(2;13) alveolar translocation.
  • Staging confirmed no evidence of metastatic disease.

Implications:

  • This case highlights the importance of thorough pathological review for rare adult brain tumors.
  • Multimodal treatment including stereotactic radiotherapy, temozolomide, and VAC chemotherapy was employed.
  • Further research into adult meningeal rhabdomyosarcoma is warranted to optimize treatment strategies.

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...

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 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...
Bacterial Meningitis01:24

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

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...
