Spontaneous cerebrospinal fluid leaks originating from multiple skull base defects
Skull Base Surgery
|January 1, 1996
Summary
Spontaneous cerebrospinal fluid (CSF) leaks from the temporal bone can arise from multiple skull base defects. Careful follow-up is crucial due to potential delays in diagnosis and presentation.
Area of Science:
- Neurosurgery
- Otolaryngology
- Neurology
Background:
- Spontaneous cerebrospinal fluid (CSF) leaks from the temporal bone are increasingly recognized.
- Most documented cases involve single, unilateral defects, often in the tegmen tympani.
Purpose of the Study:
- To report on spontaneous CSF leaks originating from multiple or distant skull base defects.
- To highlight the diagnostic and management challenges posed by multisite spontaneous CSF leaks.
Main Methods:
- Case report of two patients with spontaneous CSF leaks from multiple skull base defects.
- Review of literature on spontaneous CSF leaks, focusing on multisite presentations.
- Discussion of potential etiologies and clinical factors.
Main Results:
- Two new cases of spontaneous CSF leaks from multiple/distant skull base defects are presented.
- One patient exhibited elevated opening pressure on lumbar puncture.
- Significant time intervals between the presentation of different leak sites were observed.
Conclusions:
- Spontaneous CSF leaks can originate from multiple, distinct skull base defects.
- Elevated opening pressure may be associated with multisite leaks.
- Long-term, careful follow-up is essential for patients treated for spontaneous CSF leaks, especially those with multiple defects.

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...
01:14Increased 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...
01:19Cerebral 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...
01:21Cerebrospinal Fluid
Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the 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,...
