"Trauma has been suggested as the aetiology, along with other non-substantiated theories, such as cystic degeneration of a pre-existing tumour or of the fatty marrow in the area. Less than half are associated with prior trauma."
"A plain radiograph, typically an OPG, is typically the only imaging performed. On occasion, CT of the jaw may be undertaken."
"Surgical exploration is often undertaken to exclude other more worrisome mandibular lesions. Typically, the surgeons report an empty cavity at the entrance in about two-thirds of cases and straw-coloured, fluid-filled cavities in about one-third of cases. Blood clot is also present occasionally. The bony cavity is scraped to generate bleeding, which is considered the treatment of choice for this condition. Other treatment methods have been tried, including packing the curetted cavity with autologous blood, autologous bone, and hydroxyapatite. Exploration surgery usually leads to healing. Recurrence is rare."
"T1: homogeneous hypointensity"
"T2: homogeneous hyperintensity"
"T1 + C: mildly enhancing"
"A plain radiograph, typically an OPG, is typically the only imaging performed. On occasion, CT of the jaw may be undertaken."
"On an intra-oral or orthopantomogram, solitary bone cysts of the mandible appear as well-defined, non-expansile radiolucent mandibular lesions. No association with the teeth. No cortical destruction."

"They are usually unilocular, non-expansile (~75%), and radiolucent, typically located above the alveolar canal and, in many cases, with a scalloped superior border that spreads between the roots of vital teeth. Large, expansile and multilocular traumatic bone cavities have been rarely described. Expansion is not characteristic of these cysts, but it is described in ~25% of cases."
