Summary
Inflammatory pseudotumor of the skull base is a rare, non-cancerous mass. Low-dose oral corticosteroids effectively treat this condition, improving symptoms and reducing tumor size.
Area of Science:
- Otolaryngology
- Neurosurgery
- Pathology
Background:
- Inflammatory pseudotumor is a rare, benign mass lesion typically affecting the skull base.
- Imaging findings can mimic nasopharyngeal carcinoma or lymphoma, necessitating biopsy for definitive diagnosis.
- Management strategies depend on lesion location, bony invasion, and adjacent structure involvement.
Observation:
- A retrospective review identified five cases of skull base inflammatory pseudotumor over five years.
- Patients were followed for one to four years post-diagnosis.
Findings:
- Maintenance oral corticosteroids demonstrated efficacy in symptom improvement.
- Radiologic tumor dimensions were significantly reduced with corticosteroid treatment.
Implications:
- Skull base inflammatory pseudotumor presents diagnostic challenges due to location, symptoms, and histology.
- Low-dose oral corticosteroids represent an effective therapeutic option for this condition.

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...
01:26Brain 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,...
01:14Increased 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...
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
