Background: The effect of clinical history on the interpretation of radiographs has been widely researched in human medicine. There is, however, no data on this topic in veterinary medicine. Hypothesis/Objectives: Diagnostic accuracy would improve when history was supplied. Animals: Thirty client-owned dogs with abnormal findings on thoracic radiographs and confirmation of the disease, and 30 healthy client-owned controls were drawn retrospectively. Methods: Retrospective case-control study. Sixty radiographic studies of the thorax were randomized and interpreted by 6 radiologists; first, with no access to the clinical information; and a second time with access to all pertinent clinical information and signalment. Results: A significant increase in diagnostic accuracy was noted when clinical information was provided (64.4% without and 75.2% with clinical information; P = .002). There was no significant difference in agreement between radiologists when comparing no clinical information and with clinical information (Kappa 0.313 and 0.300, respectively). Conclusions and Clinical Importance: The addition of pertinent clinical information to the radiographic request significantly improves the diagnostic accuracy of thorax radiographs of dogs and is recommended as standard practice.

An 8-year-old intact male German Shorthaired Pointer presented as a referral for a one-week history of unilateral ocular discharge of the left eye and progressive temporalis muscle atrophy. Severe temporalis muscle wasting was appreciated, with periorbital asymmetry. Computed tomography showed aggressive and extensive multifocal bone lysis, primarily on the left rostral aspect of the skull, affecting the cribriform plate, frontal bone, ethmoid bone, zygomatic bone, and maxilla, with marked left temporal muscle atrophy and near-complete collapse and destruction of the left frontal sinus. Bone biopsy revealed osteoblastic osteosarcoma of the skull. Aside from the physical examination abnormalities, the patient did not exhibit pain, lethargy or anorexia at home or while in hospital. This case is notable for the unusual presentation, clinical manifestation and location of osteoblastic osteosarcoma in dogs. The survival time of 132 days was calculated starting from the date of confirmed histopathologic diagnosis, or 159 days from the date of the computed tomography scan.

A 4‐year‐old neutered male Labrador retriever presented with acute‐onset nonweight‐bearing lameness of the right forelimb following play activity. Physical examination revealed crepitus and pain on elbow flexion. Radiographic examination showed a linear lucency at the cranial margin of the medial coronoid process of the ulna (MCP), with sclerosis and periosteal new bone formation, consistent with degenerative joint disease secondary to elbow dysplasia (ED). Computed tomography (CT) identified two distinct fragments adjacent to the MCP. Arthroscopic partial coronoidectomy was performed with successful retrieval of both fragments. On histopathological examination, one fragment demonstrated chronic changes, consistent with dysplasia‐related FMCP, whereas the other exhibited features consistent with acute trauma/fracture. The patient recovered well at 6‐week postoperative evaluation. This is the first reported case of concurrent developmental FMCP and traumatic MCP fracture in the same limb in a canine patient, confirmed via multimodal imaging and histopathology. This report highlights the diagnostic role of CT imaging and histopathology in differentiating overlapping pathologies and raises the question whether underlying ED plays a role in secondary traumatic injuries in dogs.
