Summary
Spinal intradural extramedullary Ewing's sarcoma is rare in children. This case details a successful resection and a rare instance of brain metastasis via cerebrospinal fluid dissemination.
Area of Science:
- Pediatric Oncology
- Neurosurgery
- Spinal Tumors
Background:
- Spinal intradural extramedullary Ewing's sarcoma is exceptionally rare in pediatric patients.
- Early diagnosis and treatment are crucial for managing spinal tumors.
Purpose of the Study:
- To report a rare case of spinal intradural extramedullary Ewing's sarcoma in a pediatric patient.
- To highlight the challenges in diagnosing and managing metastatic Ewing's sarcoma.
Main Methods:
- Case report of a 15-year-old boy.
- Surgical resection of the primary spinal tumor.
- Postoperative MRI for confirmation.
- Biopsy of a third ventricle lesion for diagnosis of metastasis.
Main Results:
- Successful total resection of the primary spinal tumor.
- Patient remained asymptomatic for 20 months post-surgery.
- Development of obstructive hydrocephalus due to a third ventricle lesion.
- Biopsy confirmed metastatic Ewing's sarcoma, representing the third documented brain metastasis and first case of CSF dissemination.
Conclusions:
- This case underscores the rarity of spinal intradural extramedullary Ewing's sarcoma in children.
- It highlights a unique pathway of cerebrospinal fluid dissemination leading to brain metastasis.
- Further research is needed to understand and treat such rare metastatic patterns.

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...
01:26Brain 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,...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
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...

01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
