Aneurysmal bone cyst of paranasal sinuses

Area of Science:

• Otorhinolaryngology
• Pathology
• Surgical Oncology

Background:

• Aneurysmal bone cysts (ABCs) are uncommon, benign, expansile bone lesions.
• They rarely occur in the paranasal sinuses, presenting diagnostic and management challenges.
• Pathogenesis remains unclear, necessitating prompt diagnosis to guide treatment and prevent recurrence.

Purpose of the Study:

• To report a rare case of aneurysmal bone cyst involving the ethmoid and maxillary sinuses.
• To emphasize the importance of early diagnosis and appropriate management of sinonasal ABCs.
• To illustrate a successful treatment outcome for this condition.

Main Methods:

• Case presentation of a patient with an aneurysmal bone cyst.
• Diagnostic workup including imaging and histopathological examination.
• Surgical management of the sinonasal lesion.

Main Results:

• The aneurysmal bone cyst involved both the ethmoid and maxillary sinuses.
• The lesion was successfully excised.
• The patient experienced a favorable outcome with no recurrence at follow-up.

Conclusions:

• Aneurysmal bone cysts, though rare, should be considered in the differential diagnosis of sinonasal masses.
• Multidisciplinary management is crucial for optimal outcomes in sinonasal ABCs.
• Early detection and surgical intervention can lead to successful management and prevent complications.
