Computed tomography-guided cementoplasty combined with radiation therapy for an aneurysmal bone cyst in a dog: a case report

Abstract

Aneurysmal bone cysts are expansile osteolytic bone lesions that can manifest clinically as lameness, pain and swelling. In humans, aneurysmal bone cysts are considered benign tumours that have been classified as primary or secondary to a previous coexisting lesion. Local recurrence after treatment or malignant transformation has been reported in both humans and in a dog. Different treatment options have been proposed. This report describes the treatment of an 11-month-old Irish wolfhound with an aneurysmal bone cyst with a combination of computed tomography-guided cementoplasty and radiation therapy, 30 Gy delivered in 10 fractions. The dog recovered completely, with no lameness observed 30 months after treatment.
