Aneurysmal Bone Cyst of Talus: Case Report of a Rare Presentation

Introduction: Aneurysmal bone cysts (ABCs) are most commonly found in the metaphysis of long bones but are reported to have been found in other locations as well. While presentation of a swelling in a short bone is unlikely to be an ABC, the possibility should be kept in mind, especially with supporting radiological findings. Case Report: In this case report, we present the case of a young female who presented to us with complaints of pain and swelling over the dorsal aspect of her right foot. Radiological investigations pointed toward a diagnosis of ABC of the talus bone, which was confirmed on histopathological examination. The patient was managed conservatively using percutaneous polidocanol injection and was relieved of her symptoms soon after. Conclusion: Although ABC is most commonly found in long bones, it can be considered a differential in other bones as well. Sclerotherapy may be considered over curettage as a treatment modality due to its numerous advantages.
