Summary
A rare spinal meningioma caused hemiparesis and gait issues in a young woman. Surgical removal offered symptom improvement, suggesting combined surgical and radiosurgical treatment for this extradural en-plaque tumor.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- Spinal meningiomas are rare tumors, with extradural en-plaque variants being exceptionally uncommon.
- This case highlights a cervical extradural en-plaque meningioma presenting with significant neurological deficits.
Observation:
- A 22-year-old woman experienced right hemiparesis and gait disturbance due to a C1-C5 spinal lesion.
- MRI revealed a dorsally compressing, well-enhanced lesion; CT showed a calcified, slightly enhanced mass.
- Surgical resection was incomplete due to lateral tumor extension.
Findings:
- Histological diagnosis confirmed cervical extradural en-plaque meningioma.
- The patient showed remarkable symptom improvement following surgery.
- Complete resection was challenging due to the tumor's anatomical involvement.
Implications:
- This case underscores the complexity of treating extradural en-plaque spinal meningiomas.
- A combined surgical and radiosurgical approach may be necessary for optimal outcomes.
- Further research into multimodal treatment strategies for these rare tumors is warranted.

01:19Cranial 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...

01:18Viral 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...
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...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
