Introduction and aim: Nonendodontic lesions can be misdiagnosed as pathoses of endodontic origin. One of the most common nonodontogenic lesions of the oral cavity is the nasopalatine duct cyst, which is difficult to distinguish from periapical lesion. The aim of this case report is to familiarize readers with differential diagnosis of this disease.

Case report: The patient who had suffered lateral luxation of tooth 11 aproximately 25 years ago presents with palatal abscess of premaxila. After non surgical retreatment of tooth 11 the symptoms disappeared, but the tooth become symptomatic two years after. After CBCT scan was taken the nasopalatine duct cyst was diagnosed and after surgical treatment histopathologically confirmed.

Discussion: The possible predisposition factors, radiological signs and differential diagnosis is disccused.

Conclusion: The understanding of anatomy, the use of appropriate diagnostic tests (including CBCT scan) to distinguish endodontic lesions from nonendodontitic pathoses are essential for accurate differential diagnosis and treatment.
