1. Simple bone cyst in right posterior mandible and ramus
A well-defined, delicately corticated radiolucency is present within the right posterior mandible and mandibular ramus, which extends from the inferior border of the mandible to the mandibular notch and from the apical aspect of tooth 47 to the posterior border of the ramus. The contiguous medial and lateral cortices of the ramus are thinned due to endosteal scalloping, but no signs of cortical breach are noted. The course of the right mandibular nerve canal is unaffected. The follicle around the crown of tooth 48 appears normal, and the cortex adjacent to the developing dental papilla remains intact adjacent to this large radiolucency. These radiographic findings are consistent with a simple bone cyst in the right posterior mandible and ramus. Radiographic follow up to monitor this region for signs of spontaneous osseous healing is recommended.
Orthogonal measurements of simple bone cyst
These orthogonal cross-sectional images demonstrate the approximate dimensions of the simple bone cyst in the right posterior mandible and ramus.
Developing tooth 48
Tooth 48 is vertically oriented relative to the long axis of tooth 47. Root development has not initiated at this time. The follicle around the crown of tooth 48 appears normal, and the cortex around the developing dental papilla is intact. No pathology is arising from the developing tooth 48.
