Multifocal Polyostotic Aneurysmal Bone Cyst of Pelvic Bones
Received Date: July 06, 2020; Published Date: July 24, 2020
Aneurysmal bone cyst (ABC) is a very rare benign osteolytic bone tumor representing less than 2% of all bone tumors and 5 to 6% of benign bone tumors. Atypical or unusual variants of ABC group together unusual clinical presentations, unusual complication, rare locations, and unusual age of occurrence, representing a real diagnostic challenge for clinicians. From all so-called unusual variants of ABC, multifocal one is particularly exceptional with only seven cases described metachronously in the world literature. We report the original case of a bifocal synchronous poly-ostotic and locally aggressive ABC involving the right ilium and the left superior pubic ramus in 19-year-old Tunisian man.
