Sinonasal sarcoidosis, rare without lung disease, affects nasal tissues. Diagnosis requires endoscopy, CT scans, and biopsy to confirm non-caseating granulomas and exclude other conditions.

Area of Science:

  • Otolaryngology
  • Pulmonology
  • Pathology

Background:

  • Sarcoidosis is a multisystem inflammatory disease.
  • Sinonasal involvement is uncommon, typically occurring with pulmonary sarcoidosis.

Purpose of the Study:

  • To describe the clinical, endoscopic, and CT findings of sinonasal sarcoidosis.
  • To emphasize the diagnostic criteria and differential diagnoses.

Main Methods:

  • Review of endoscopic and CT imaging features.
  • Histopathological confirmation of non-caseating granulomas.

Main Results:

  • Commonly affects nasal septum and inferior turbinates.
  • CT may show mucosal nodules, sinus opacification, and inflammatory rhinitis.

  • Severe cases can lead to septal perforation, bone/cartilage destruction, and saddle nose deformity.

    • Conclusions:

    • Diagnosis relies on a combination of clinical, imaging, and histological findings.
    • Biopsy is crucial to differentiate from other granulomatous diseases.
    • Early diagnosis and management are important to prevent severe nasal deformities.
