Summary
Allergic fungal sinusitis (AFS) can present as cavernous sinus syndrome, a rare but serious condition. Early recognition by ophthalmologists is crucial for timely management of this noninvasive fungal sinusitis.
Area of Science:
- Otorhinolaryngology
- Ophthalmology
- Mycology
Background:
- Allergic fungal sinusitis (AFS) is an uncommon noninvasive fungal infection of the paranasal sinuses, typically affecting immunocompetent individuals.
- Sphenoid sinus involvement in AFS can lead to severe complications, including proptosis and vision loss.
Observation:
- A case of AFS presenting as posterior cavernous sinus syndrome is described.
- A 59-year-old male presented with right complete ptosis and ophthalmoplegia.
Findings:
- Endonasal sphenoid surgery revealed characteristic allergic fungal mucin.
- Cavernous sinus syndrome was identified as a rare clinical manifestation of AFS.
Implications:
- Ophthalmologists must consider AFS in the differential diagnosis of cavernous sinus syndrome.
- Timely referral and appropriate management are essential for patients with this rare presentation of AFS.

01:24Cystic Fibrosis: Management
334
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

01:23Chronic Pharyngitis
9.0K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
4.1K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.

01:27Cranial Bones: Lateral View
4.1K
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...
