Tornwaldt cysts are rare, benign lesions that typically reside along the posterior wall of the nasopharynx. They are often discovered incidentally during routine imaging studies and can pose a diagnostic challenge due to their asymptomatic nature. This case report presents the incidental finding of a Tornwaldt cyst on a CT in an asymptomatic patient and highlights the lack of intervention required. The patient, a 28-year-old male, underwent a postoperative CT scan following septoplasty for a nasal septum deviation, revealing a well-defined cystic lesion in the midline of the nasopharynx consistent with a Tornwaldt cyst. Despite the presence of the cyst, the patient did not exhibit any associated symptoms such as nasal obstruction, headache, or recurrent infections. This case emphasizes the importance of recognizing and differentiating Tornwaldt cysts from other pathologies, as misdiagnosis and unnecessary interventions can lead to potential complications. Asymptomatic Tornwaldt cysts generally do not necessitate active intervention, but ongoing vigilance and individualized patient care remain vital to ensure optimal outcomes.
