Asymptomatic Rhinolith Diagnosis Through MR and CBCT Imaging: A Case Report

Aim Rhinoliths are rare calcified masses that form in the nasal cavity due to the progressive accumulation of calcium and magnesium salts around a central nidus. This case report aims to highlight the crucial role of dental professionals in the incidental detection of rhinoliths during routine radiographic examinations and to emphasize the importance of comprehensive radiographic evaluation and interdisciplinary collaboration for accurate diagnosis and timely management. Case Report The current report presents a case of a 42-year-old female patient who presented to the Istanbul University Faculty of Dentistry for a routine dental examination. A panoramic radiograph revealed an elliptical, opacified mass in the left nasal fossa and medial maxillary sinus. Cone Beam Computed Tomography (CBCT) confirmed a well-demarcated calcified lesion measuring 20.7 × 11.2 × 10.9 mm in the left inferior turbinate, with surrounding mucosal thickening. Retrospective review of the patient’s prior Magnetic Resonance Imaging (MRI) scans from 2021, obtained for an unrelated meningioma assessment, demonstrated an unreported elliptical lesion with a hyperintense periphery causing narrowing of the nasal passage. The patient was asymptomatic and had no recollection of previous nasal foreign body insertion. Discussion Rhinoliths are often asymptomatic and incidentally detected in radiographic imaging. Accurate diagnosis and timely otolaryngologic referral are essential to prevent potential complications. Conclusion This case underscores the critical role of dental professionals in identifying incidental rhinoliths during routine radiographic evaluations. A comprehensive radiographic evaluation, integrated with interdisciplinary collaboration, is imperative for the early diagnosis and prevention of complications associated with longstanding rhinoliths.
