Bilateral nasolabial cysts: MRI findings in a rare case report

Abstract

Nasolabial cysts are rare, benign, nonodontogenic, extraosseous maxillofacial lesions, with bilateral involvement being uncommon. A 40-year-old woman presented with long-standing bilateral nasal vestibular swelling. Magnetic resonance imaging (MRI) demonstrated well-defined bilateral cystic lesions along the nasal floor with characteristic signal intensities and smooth anterior maxillary bone scalloping, consistent with bilateral nasolabial cysts containing internal debris. This case highlights the characteristic MRI appearance of bilateral nasolabial cysts and emphasizes the role of MRI in accurate diagnosis and surgical planning.
