Summary
Odontogenic maxillary sinusitis can rarely present as a bone-like mass, mimicking fungal sinusitis. Surgical removal and histopathology confirmed a bone sequestrum, not fungal infection, aiding diagnosis.
Area of Science:
- Otorhinolaryngology
- Oral and Maxillofacial Surgery
- Pathology
Background:
- Calcified masses in the maxillary sinus often indicate fungal sinusitis, typically aspergillosis.
- Odontogenic maxillary sinusitis can rarely present with bone-like calcified masses, posing diagnostic challenges.
- Distinguishing between fungal and odontogenic causes is crucial for appropriate treatment.

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
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,...
