Summary
This study reports the first case of an angiomyolipoma (AML) in the maxillary sinus, a rare benign tumor. Identifying fat within the mass on imaging can aid in preoperative diagnosis of this unusual sinonasal condition.
Area of Science:
- Otolaryngology
- Radiology
- Pathology
Background:
- Sinonasal masses are frequently encountered in otolaryngology practice.
- Common conditions include sinonasal polyps and mucus retention cysts.
- Unusual conditions necessitate a comprehensive differential diagnosis.
Observation:
- A 78-year-old man presented with an incidentally discovered maxillary sinus mass on brain imaging.
- Biopsy confirmed the mass as an angiomyolipoma (AML).
- This represents a rare extrarenal location for AML and the first reported case in a maxillary sinus.
Findings:
- Angiomyolipomas (AMLs) are benign hamartomatous tumors.
- Few AML cases have been reported in the nasal cavity.
- Intratumoral fat on imaging may suggest AML preoperatively.
Implications:
- Awareness of AML as a potential diagnosis in the maxillary sinus is crucial.
- Interdisciplinary collaboration aids in patient management.
- Imaging features like a fat-containing mass can guide differential diagnosis for sinonasal lesions.
