Solitary bone cysts-A rare occurrence with bilaterally symmetrical presentation

Abstract

Solitary bone cysts (SBCs) are bone cavities that lack a true epithelial lining. They are more commonly seen during the first 2decades of age.Very few cases have been reported over 40 years of age.SBCs are usually discovered as an accidental coexisting finding during a routine radiologic examination or during another unrelated dental complaint. They present as a unilocular or multilocular radiolucent lesion associated with vital teeth with mild or no cortical expansion. Bilateral presentation is however very rare. We present a case of 52-year-old female patient with bilateral presentation of SBCs.
