Pseudotumoral allergic fungal sinusitis with skull base involvement
Summary
Allergic fungal sinusitis can mimic tumors, presenting diagnostic challenges. Successful non-surgical treatment with corticosteroids and itraconazole was achieved for a skull base recurrence.
Area of Science:
- Otolaryngology
- Neurosurgery
- Radiology
Background:
- Allergic fungal sinusitis (AFS) is an inflammatory condition.
- Pseudotumoral recurrence can complicate AFS, mimicking neoplastic processes.
Observation:
- A case of AFS with pseudotumoral recurrence involving the skull base is presented.
- The recurrence exhibited misleading radiological and clinical features.
Findings:
- Successful treatment was achieved using systemic corticosteroids and itraconazole.
- Surgical intervention was not required for this case.
Implications:
- Highlights the importance of recognizing AFS pseudotumoral recurrence.
- Emphasizes non-surgical management options for specific AFS presentations.
- Underscores the need for multidisciplinary collaboration among ENT specialists, neurosurgeons, ophthalmologists, and radiologists.

Brain Abscess l: Introduction
21
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...

Bacterial Meningitis II: Pathophysiology
24
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Cranial Bones: Lateral View
6.8K
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...
