Pneumosinus dilatans is a rare condition causing maxillary sinus expansion. This aggressive case successfully treated with endoscopic sinus surgery demonstrates effective management of orbital, cheek, and nasal cavity involvement.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Radiology

Background:

  • Pneumosinus dilatans is an exceptionally rare condition characterized by abnormal enlargement of a paranasal sinus.
  • Aggressive presentations, particularly involving adjacent structures, pose significant diagnostic and therapeutic challenges.

Observation:

  • A rare, aggressive case of maxillary pneumosinus dilatans is detailed.
  • Imaging via computed tomography (CT) and magnetic resonance imaging (MRI) revealed extensive lesion involvement.
  • The lesion infiltrated the orbit, cheek, and nasal cavity.

Findings:

  • Surgical intervention via endoscopic sinus surgery (FESS) successfully reopened the affected maxillary sinus.
  • The FESS procedure addressed the extensive nature of the lesion.

Implications:

  • This case highlights the successful application of FESS in managing complex and aggressive pneumosinus dilatans.
  • It underscores the importance of advanced imaging in delineating the extent of such rare lesions.
  • Effective surgical management can lead to favorable outcomes even in extensive infiltrations.
