[Benign but not harmless intracranial hypertension: a case report]
Summary
Benign intracranial hypertension (BIH), a condition of increased intracranial pressure, can threaten vision. Prompt diagnosis and treatment are crucial for recovery and preventing relapse.
Area of Science:
- Neurology
- Ophthalmology
Background:
- Benign intracranial hypertension (BIH) is defined by elevated intracranial pressure without identifiable causes like tumors or hydrocephalus.
- Despite its name, BIH poses a significant risk to visual prognosis.
Observation:
- A 15-year-old female presented with lymphocytic meningitis, subsequently developing secondary BIH.
- Clinical manifestations included elevated cerebrospinal fluid pressure (70cm H2O), bilateral 6th nerve palsy, decreased visual acuity, and papilledema, without ventricular enlargement.
Findings:
- A comprehensive workup failed to identify an underlying etiology for the BIH.
- Treatment involved oral acetazolamide and repeated (9) depletive spinal taps.
- Complete normalization of clinical and ophthalmological findings occurred within 8 weeks.
Implications:
- This case highlights that BIH is often mislabeled as 'benign' due to its potential for severe visual impairment.
- Emphasizes the critical need for early diagnosis and effective management strategies for BIH.
- Suggests that BIH, even when secondary to meningitis, requires vigilant monitoring and intervention to preserve vision.

01:14Increased 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...
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...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
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...
01:19Cerebral 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...
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,...
