Objectives: Epithelium at the apex of a nonvital tooth can be presumably stimulated by inflammation to form a true epithelium-lined cyst, or radicular cyst. Radicular cyst is the most frequent cyst found in the jaw (between 38% to 68% all jaw cysts). Most of the radicular cysts are found in the maxilla, especially around incisors and canines. Some of the periapical lesions can extend to the surrounding tissues and it is not uncommon to find them way around the apex of involved teeth. 

Case Report: A 47- year old man with no past medical history was referred to the department of oral and maxillofacial radiology of Tehran University of Medical Sciences, with a complaint of a painless swelling on the buccal cortex of the left maxilla. The swelling was smooth-surfaced. Patient's panoramic radiography revealed well-defined unicystic radiolucency extended from alveolar crest to the floor of the orbit. The area was examined with conventional computed tomography to evaluate bone involvement. On axial view of CT images of the patient, an expansile lesion with 34*28 mm dimension was seen and the buccal cortex, medial and lateral walls of maxillary sinus and the lateral wall of nasal cavity were also eroded and in some parts were perforated. Under general anesthesia and with releasing incision, access to the left maxillary sinus with the Caldwell luc method was available. After complete excision the lesion, curettage of the remaining walls and peripheral osteotomy was performed. 

Conclusion: This presentation describes an unusual case of large radicular cyst involving maxillary sinus and its treatment. Radiological examinations provided valuable information.
