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.
The asymptomatic patient, a 60-year-old man, was referred to a radiology clinic to undergo examination for the purpose of implant planning. The panoramic radiograph revealed no important alterations in the mandible (). The patient underwent multidetector computed tomography (MDCT) (Synergy Helicoidal, General Electric Company, Milwaukee, WI), with slices and intervals of 0.625 mm, field of view 15.8 cm, matrix 512 × 512, standard filter, 120 kV and 200 mA.\nThe tomographic images clearly showed multiple cavitary defects, two in the anterior region (anterior variant) and one in the posterior region (posterior variant) (Figures , , and ). Intracavitary tomographic density (Hounsfield units) suggested glandular tissue in the anterior defects and fat in the posterior defect.
