Abstract
|
|
|
50-year-old female and 50-year-old male were referred to the department of the oral and maxillofacial surgery of
Kyungpook national university dental hospital with asymptomatic lesions on their posterior mandibular body areas. They
were discovered incidentally on panoramic radiographs during routine dental examination. Physical examination revealed
no remarkable findings. Each panoramic radiograph showed well defined radiolucent lesions without hyperostotic border
on their posterior mandibular body area. At first they were diagnosed as benign tumors because they looked like
multilocular pattern and one of the patient showed discontinuity of mandibular canal within the lesion. CT scans
demonstrated well demarcated and irregular lingual depression filled with fat tissue and they were diagnosed as
developmental salivary gland defects. One of the lesion showed no change on follow-up panoramic radiograph after 4
months. Developmental salivary gland defects resembling benign tumor are atypical cases and it is suggested that
confirmatory imaging using CT or MRI should be taken.
