Radiographs: Bone Tumours and Infections

This free Veterinary Webinar is produced by London Vet Specialists with Dr Ian David Jones BVetMed, MVetMed, CertVDI, DipECVDI, PhD, MRCVS. The webinar recording describes and shows us the radiographic features of bone tumours and bone infection.

Dr Jones begins with a step by step guide to differentiating between aggressive bone lesions and non aggressive bone lesions, using assessment of cortisol destruction, periosteal reaction, and the transition zone. Useful examples of the different types of cortisol destruction are shown, namely geographic, moth-eaten and permeative.

Periosteal reactions may be regular (smooth) or irregular (spiculated or columnar): we see examples of all of these. The zone of transition may be distinct or indistinct – Dr Jones shows examples of each and explains the significance.

Once classified as aggressive, how do you differentiate between neoplasia (primary vs metastatic) and infectious (bacterial osteomyelitis vs fungal osteomyelitis)? Dr Jones answers this question and goes on to discuss case examples.
