Bone Cement Treatment for Aneurysmal Bone Cyst in a Dog

Abstract

ABSTRACT. An eighteen month old female Doberman pinscher dog was referred to teaching hospital of Adnan Menderes University, Faculty of Veterinary Medicine with the complaint of right forelimb lameness for a month. On the basis of clinical, radiographical, scintigraphical, computed tomographical and histopathological findings, aneurysmal bone cyst was diagnosed. Surgical curettage and bone cement treatment were applied. The patient recovered after 12 months. This case proves that aneurysmal bone cyst, without osteolysis and/or damages to the surrounding tissues, may result in a good prognosis if curettage and treatment with bone cement are done. KEY WORDS: aneurysmal bone cyst, bone cement, canine.

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

“…Aneurysmal bone cysts (ABCs) are expansile osteolytic bone lesions comprised of large vascular sinusoids divided into blood-filled cavities by connective tissue septa that can manifest clinically as non-weight-bearing lameness, pain and swelling (Dowdle et al 2003;Sarierler et al 2004;Van De Luijtgaarden et al 2009). …”

“…Since first being described in 1942 (Mendenhall et al 2006), ABCs were defined as benign, non-neoplastic lesions in the bone, probably as a result of a primary injury such as trauma; a bone tumour or fibrous dystrophy of the bone, which in turn could cause a haemodynamic disturbance that increased the venous pressure; and primary or secondary to arteriovenous malformation and bony reaction (Szendroi et al 1998;Barnhart 2002;Sarierler et al 2004;Mei et al 2009). A hereditary predisposition in Doberman pinchers has also been reported (Sarierler et al 2004;Dernell et al 2007).…”

“…Most commonly, ABCs appear in the metaphysis of long bones, but they have also been reported in the vertebra, pelvis, rib and scapula (Barnhart 2002). Although the ABC is benign, the risk of local recurrence after treatment has been described in the literature (Feigenberg et al 2001;Sarierler et al 2004;Mendenhall et al 2006). Also, malignant transformation has been reported in humans and in a Labrador retriever previously treated with different surgical procedures (Barnhart 2002;Mei et al 2009).…”

“…Also, malignant transformation has been reported in humans and in a Labrador retriever previously treated with different surgical procedures (Barnhart 2002;Mei et al 2009). ABCs do not usually metastasise (Sarierler et al 2004) but one case of lung, liver and kidney metastasis in a human patient has been described (Van De Luijtgaarden et al 2009). In humans, treatment options include radiotherapy, en bloc resection for expendable bones, curettage, bone graft or bone graft substitute like polymethylmethacrylate (PMMA) filling of the defect, also known as bone cementation.…”

“…In humans, treatment options include radiotherapy, en bloc resection for expendable bones, curettage, bone graft or bone graft substitute like polymethylmethacrylate (PMMA) filling of the defect, also known as bone cementation. Cryosurgery, phenolisation, cauterisation, arterial embolisation, steroid injection and calcitonin have been used as adjuvants to the classic treatments (Feigenberg et al 2001;Barnhart 2002;Sarierler et al 2004). In dogs, treatment options that have been reported include curettage, cancellous bone graft, autograft, filling the lesion with PMMA, and amputation (Barnhart 2002;Dowdle et al 2003;Sarierler et al 2004).…”
