Insights

A choroid plexus cyst caused intermittent obstructive hydrocephalus in an infant. Endoscopic cyst fenestration resolved the condition, offering a unique case study for pediatric neurosurgery.

Area of Science:

  • Pediatric Neurosurgery
  • Neuroimaging
  • Congenital Neurological Disorders

Background:

  • Hydrocephalus in infants can arise from various causes, including intraventricular cysts.
  • Choroid plexus cysts are common but rarely cause significant obstructive hydrocephalus.

Observation:

  • An 11-week-old infant presented with acute symptoms of hydrocephalus, including vomiting and lethargy.
  • Initial CT scan confirmed hydrocephalus, which transiently resolved.
  • MRI revealed intermittent third ventricular obstruction by a choroid plexus cyst.

Findings:

  • The choroid plexus cyst intermittently obstructed the third ventricle, leading to obstructive hydrocephalus.
  • Endoscopic fenestration of the cyst successfully treated the condition.

Implications:

  • This case highlights the importance of considering intermittent obstruction in pediatric hydrocephalus.
  • Endoscopic fenestration is an effective treatment for hydrocephalus secondary to third ventricular choroid plexus cysts.
  • Early diagnosis and intervention are crucial for favorable outcomes in infantile hydrocephalus.

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Cerebral 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...
