Summary
Recurrent extracranial arachnoid cysts, though rare, require thorough dural exploration for permanent treatment. This case highlights successful management of a previously unreported recurrent extracranial arachnoid cyst in an adult.
Area of Science:
- Neurosurgery
- Radiology
- Pathology
Background:
- Arachnoid cysts are common, often intracranial congenital malformations.
- Secondary arachnoid cysts arise from bone defects and incomplete dural closure.
- Intradiploic arachnoid cysts are rare, typically post-traumatic skull lesions.

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,...
01:14Increased 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...
