Selective arterial embolization of aneurysmal bone cyst in the pubic bone: A possible primary treatment

Abstract

Aneurysmal bone cyst is a benign highly vascular lesion that occurs in children. Traditionally ABCs were treated by surgical resection. However, lesions at difficult to access anatomical locations such as the pelvis have higher morbidity when treated surgically. Recently with the advances in endovascular treatment selective arterial embolization became a promising option for primary treatment of ABC. The authors present a case of a 14-year-old female with a pelvic ABC that was successfully treated by selective arterial embolization. Selective arterial embolization is a cost-efficient way of managing ABC especially in cases where surgical treatment carries high risk.

The treatment of aneurysmal bone cysts

“…The single-centered retrospective study of Döring et al on surgical treatment of ABCs covers some of the latest insights in using curettage with or without adjuvants and/or filling [ 42 ]. They reported an overall recurrence rate of 28 of 90 patients (31%), and a 1, 2 and 5 years recurrence-free survival of 83, 77 and 66%, respectively.…”

“…A large amount of case series into rare locations of ABCs have been published recently [ 47 , 48 ▪ ]. Localization of ABC in the hands and feet had significantly less recurrences compared with other locations in Döring et al [ 42 ]. Less aggressive treatment might be considered in these loci.…”
