Summary
This case study highlights an intradiploic encephalocele diagnosed using advanced imaging. Single photon emission computed tomography (SPECT) confirmed the diagnosis, suggesting surgery may not be needed if asymptomatic.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Intradiploic encephaloceles are rare congenital skull defects.
- Diagnosis can be challenging due to non-specific symptoms and imaging findings.
Observation:
- A 66-year-old man presented with dizziness and right parietal bone abnormalities on imaging.
- CT revealed bone destruction, and MRI showed a lesion in the intradiploic space near the central sulcus.
- Single photon emission computed tomography (SPECT) demonstrated normal cerebral blood flow, consistent with encephalocele.
Findings:
- The neuroimaging diagnosis was intradiploic encephalocele.
- The lesion's proximity to the central sulcus posed surgical risks for biopsy.
- SPECT imaging was crucial in differentiating encephalocele from other pathologies.
Implications:
- Asymptomatic intradiploic encephaloceles may not require surgical intervention.
- SPECT is a valuable tool for diagnosing encephaloceles and guiding treatment decisions.
- This case underscores the importance of comprehensive neuroimaging in managing skull base abnormalities.

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...
01:26Brain 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...
01:29Increased 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...
