Insights

Giant choroid plexus cysts are rare in children and can cause symptoms like increased head circumference. Surgical removal of this giant cyst led to an excellent recovery in a 15-month-old boy.

Area of Science:

  • Pediatric Neurosurgery
  • Developmental Neurobiology
  • Cystic Lesions of the Brain

Background:

  • Choroid plexus cysts (CPCs) are intraventricular formations that are typically asymptomatic.
  • Large or giant CPCs are exceptionally rare in the pediatric population, posing diagnostic and management challenges.

Observation:

  • A 15-month-old male presented with macrocephaly and a left parietal bony deformity.
  • Imaging revealed a giant choroid plexus cyst causing significant mass effect.

Findings:

  • The patient underwent successful open resection of the giant choroid plexus cyst.
  • Histopathological analysis confirmed the diagnosis of a choroid plexus cyst.

Implications:

  • This case highlights the importance of considering giant CPCs in the differential diagnosis of pediatric intraventricular masses.
  • Surgical intervention can be highly effective for symptomatic giant CPCs, leading to favorable outcomes.

Increased Intracranial Pressure l: Introduction01:14

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...

Increased 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...
Cerebral Edema l: Introduction01:19

Cerebral Edema l: Introduction

Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Cerebral Edema ll: Pathophysiology01:22

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...
