Summary
Ruptured central nervous system (CNS) vascular malformations can cause sudden death. Forensic examination requires thorough gross and histologic evaluation to identify these often-invisible lesions and accurately determine the cause of death.
Area of Science:
- Neurology
- Forensic Pathology
- Vascular Medicine
Background:
- Central nervous system (CNS) vascular malformations are recognized causes of sudden, non-traumatic death due to rupture and intracranial hemorrhage.
- These lesions are underrepresented in forensic literature, despite their potential lethality.
- Accurate identification is crucial for determining the cause of death and understanding disease progression.
Observation:
- Four cases of sudden, non-traumatic death attributed to ruptured CNS vascular malformations are presented.
- In all cases, the source of bleeding was not grossly apparent and required extensive histologic examination for diagnosis.
- The definitive vascular malformation was often missed during initial gross autopsy.
Findings:
- Ruptured CNS vascular malformations are frequently not visible upon gross examination following intracranial hemorrhage.
- Histologic examination is essential for diagnosing these often-occult vascular lesions.
- Failure to identify these malformations can lead to misclassification of the cause of death.
Implications:
- Accurate identification of CNS vascular malformations through meticulous gross and histologic examination is vital for forensic pathologists.
- Precise cause-of-death assignment has significant implications for surviving family members and legal proceedings.
- Improved diagnostic accuracy enhances the understanding of the natural history and forensic significance of these intracranial vascular lesions.

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...
01:29Increased 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...
01:17Hemorrhagic 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...
01:22Cerebral 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...
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
