Summary
Concurrent multiple meningiomas and cavernous hemangiomas are rare, especially when occurring without prior radiation. This report details a unique de novo case, contributing to the limited understanding of these co-occurring brain tumors.
Area of Science:
- Neuro-oncology
- Vascular Neurology
- Neurosurgery
Background:
- Intracerebral meningiomas and cavernous hemangiomas are common brain tumors.
- Multiple occurrences are linked to genetic syndromes like neurofibromatosis type 2 and familial cavernous malformations.
- Concurrent meningiomas and cavernous hemangiomas are exceptionally rare, with most cases associated with prior radiotherapy.
Purpose of the Study:
- To report the second known case of concurrent multiple meningiomas and cavernous hemangiomas occurring de novo.
- To contribute to the understanding of non-radiation-associated co-occurrence of these tumor types.
Main Methods:
- Case report of a patient with concurrent multiple meningiomas and cavernous hemangiomas.
- Detailed clinical and radiological evaluation.
- Review of existing literature on concurrent meningiomas and cavernous hemangiomas.
Main Results:
- The patient presented with multiple meningiomas and multiple cavernous hemangiomas.
- The co-occurrence was confirmed to be de novo, with no history of radiation exposure.
- This represents the second reported case of its kind in the absence of radiotherapy.
Conclusions:
- Concurrent multiple meningiomas and cavernous hemangiomas can occur de novo.
- Further research is needed to elucidate the potential underlying mechanisms for non-radiation-associated co-occurrence.

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