Summary
Calcified chronic subdural hematoma, a rare condition, can present with multiple cavities. This case highlights an unusual imaging pattern of "armoured brain" with over four calcified cavities, improving after surgery.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Calcified chronic subdural hematoma (CSDH) is a rare neurological condition with variable neuroradiological presentations.
- Calcification in CSDH ranges from thin inner membranes to dense ossification.
- Prior reports documented a maximum of two hematoma cavities with calcified membranes.
Observation:
- A patient presented with bilateral symptomatic CSDH, termed "armoured brain", exhibiting signs of increased intracranial pressure.
- Computerized tomography revealed multiple, bilateral hematoma cavities with thin calcified inner membranes.
- Neurosurgical intervention involved bilateral burr hole trepanation.
Findings:
- The patient's case displayed an uncommon imaging pattern of CSDH.
- More than four distinct hematoma cavities were identified.
- These cavities were delineated by thin calcified inner membranes, exhibiting both convex and concave configurations.
Implications:
- This case expands the understanding of CSDH imaging variability.
- Recognizing such complex presentations is crucial for accurate diagnosis and timely intervention.
- Surgical management can lead to significant clinical improvement in patients with complex CSDH.

01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
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...
01:26Brain 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...
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...
