Summary
Subdural hematoma (SDH) can rarely be caused by skull cancer. This case highlights angiosarcoma of the skull presenting as SDH, emphasizing the need for thorough examination of surrounding tissues for diagnosis.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Metastatic cancers to the skull or dura can cause subdural hematoma (SDH), though infrequently.
- Underlying malignancies are typically known when SDH occurs in this context.
Observation:
- A 75-year-old man presented with sensorimotor disturbances following minor head trauma.
- Initial imaging revealed subdural hematoma (SDH), treated surgically.
- Recurrent SDH prompted a second surgery, revealing skull epithelioid angiosarcoma.
Findings:
- Histological examination of the initial surgery's bone flap and dura showed no abnormalities.
- The recurrent SDH was found to be caused by an epithelioid angiosarcoma originating from the skull.
- Biopsying surrounding tissues during the first surgery might have led to earlier diagnosis.
Implications:
- Subdural hematoma (SDH) can be an unusual presentation of primary skull or dural malignancies.
- Histological examination of surrounding tissues, beyond the hematoma capsule, is crucial for diagnosing rare tumors.
- Early diagnosis of skull angiosarcoma presenting as SDH is challenging but critical.

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...
01:22Cerebral 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...
01:17Hemorrhagic 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,...
01:19Cerebral 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...
01:29Increased 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...
