Summary
Treatment for post-infective hydrocephalus varies by meningitis type. Pyogenic meningitis requires CSF sterilization and ventricular drainage, while tuberculous meningitis may not need CSF diversion unless symptoms worsen.
Area of Science:
- Neurology
- Infectious Diseases
- Neurosurgery
Background:
- Post-infective hydrocephalus results from fluid accumulation in the brain following meningitis.
- Pyogenic meningitis causes fibrous adhesions in ventricles and arachnoid villi.
- Tuberculous meningitis leads to primarily basal fibrosis.
Purpose of the Study:
- To review treatment strategies for hydrocephalus secondary to meningitis.
- To differentiate management based on the type of meningitis (pyogenic vs. tuberculous).
Main Methods:
- Review of author's personal case series.
- Comprehensive literature review on post-infective hydrocephalus.
Main Results:
- Treatment for pyogenic meningitis involves cerebrospinal fluid (CSF) sterilization and ventricular drainage.
- Conversion of multiloculated cavities to a single cavity is crucial for pyogenic cases.
- CSF diversion is not always necessary for tuberculous meningitis.
Conclusions:
- Management of post-infective hydrocephalus depends on the causative meningitis.
- Tuberculous meningitis treatment should reserve CSF diversion for progressive cases with increased ventricular size and pressure.
- Effective management aims to resolve CSF circulation issues and prevent neurological damage.

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...
01:26Brain 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,...
01:22Cerebral 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...
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
01:26Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...
