A 31-year-old asymptomatic male patient was referred to Secunderabad Dental Imaging Centre (Hyderabad, India) to undergo routine panoramic radiography. The panorama revealed a cystic lesion in the left posterior mandible just anterior to the mandibular angle and below the third molar and mandibular canal.() There was no significant medical or dental history. There was no tenderness on bidigital palpation at the site of the lesion. For further analysis, CBCT restricted to the area of lesion was performed. The results revealed a complete radiolucent lesion that was regular, oval in shape, and well corticated.() The lesion was located below the mandibular canal and measured 11.8×8.4×14.1 mm (height×breadth×length).() The long axis of the lesion was placed horizontally on the left side. The cross-sections revealed a close relationship with the mandibular nerve without any pressure effect.() The patient was asymptomatic and there was no parasthesia or anaesthesia. The buccal wall was intact and there was no expansion (); however, the lingual wall was involved. The inferior border was also intact with little pressure atrophy.\nA radiographic diagnosis of SBC was considered and the patient was advised to undergo regular follow-up examinations.
