Summary
A rare inflammatory pseudotumor mimicked a brain tumor in a 47-year-old man. Surgical removal confirmed the lesion was benign, offering a diagnosis for his neurological symptoms.
Area of Science:
- Neurology
- Pathology
Background:
- Inflammatory pseudotumor is a rare condition with unknown causes.
- It presents as a sclerosing inflammation that can mimic neoplastic lesions clinically and radiographically.
Observation:
- A 47-year-old male experienced sudden headache and dysarthria.
- Imaging revealed a hyperdense mass in the left lateral ventricular trigone.
- MRI showed characteristic signal intensities, and angiography indicated a possible choroid plexus origin.
Findings:
- The mass demonstrated repeated hemorrhages during hospitalization.
- Histopathology confirmed hemorrhage and fibrosis with lymphoplasmacytic infiltration, consistent with inflammatory pseudotumor.
- The lesion was successfully resected via a left occipital transcortical approach.
Implications:
- This case highlights the importance of considering inflammatory pseudotumor in the differential diagnosis of intraventricular brain masses.
- Accurate diagnosis through histopathology is crucial for appropriate management.
- Successful surgical resection can resolve symptoms associated with these benign 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...
01:17Hemorrhagic 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...
01:26Brain 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,...
