Summary
Intracranial marginal zone B-cell lymphoma, a rare dural-based mass, was diagnosed in a patient with seizures. Early histopathological diagnosis and radiotherapy are crucial for effective treatment and preventing recurrence.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Intracranial marginal zone B-cell lymphoma is an uncommon dural-based mass.
- Accurate differentiation from other dural lesions is challenging.
Observation:
- A 45-year-old woman presented with seizures and speech disturbance, initially suspected as subdural hematoma (SDH).
- Radiological findings were inconclusive, and conservative management failed.
- Intraoperative findings revealed dural plaque-like thickening, leading to biopsy.
Findings:
- Histopathological and immunohistochemical analyses confirmed mucosa-associated lymphoid tissue (MALT) lymphoma.
- The patient successfully underwent radiotherapy with no complications or recurrence.
Implications:
- Highlights the importance of early diagnosis and treatment for primary dural lymphoma.
- Emphasizes the necessity of histopathological evaluation for definitive diagnosis.
- Underscores the limitations of MRI in differentiating SDH from diffuse dural infiltrative 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...
01:26Brain 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,...
