Summary
Schneiderian papilloma, a rare sinus tumor, can cause severe symptoms. This case highlights its aggressive potential, even in benign forms, with extensive intracranial spread in an elderly patient.
Area of Science:
- Otolaryngology
- Neurosurgery
- Oncology
Background:
- Schneiderian papilloma (inverted papilloma) is an uncommon, typically benign tumor originating in the paranasal sinuses.
- It frequently presents as unilateral nasal obstruction.
Observation:
- A 92-year-old woman experienced severe proptosis, vision loss in her left eye, and rhinorrhea.
- A visible mass was noted in her left nostril.
Findings:
- Neuroimaging revealed the inverted papilloma extended from the left paranasal sinus to the frontal sinuses.
- The tumor showed secondary spread into the cranial cavity and brain substance.
Implications:
- This case underscores the potential for aggressive behavior and extensive invasion of inverted papillomas, regardless of their benign nature.
- It highlights the importance of thorough diagnostic evaluation and management for sinonasal tumors, especially in elderly patients.
- Advanced imaging is crucial for assessing the full extent of tumor invasion, including intracranial involvement.
