The MRI appearance of appendicular septic physitis has not been reported in small animals. MRI appearance of septic arthritis and osteomyelitis has been described in horses, and the use of MRI has been proposed as a diagnostic alternative to radiographs to allow for earlier diagnosis and treatment. MRI is also routinely used in human medicine for the diagnosis of osteomyelitis owing to increased accuracy of evaluation of the soft tissue involvement. In the case of a 5 mo old male boxer dog described here, radiographs were suggestive of the diagnosis of septic physitis, although an MRI was obtained to rule out neurologic etiologies of lameness based on history and physical exam findings. MRI identified a fluid pocket communicating with the physis. The diagnosis of septic physitis was then confirmed via ultrasound-guided fine-needle aspirate of the fluid pocket communicating with the physis that was seen on the MRI.
小动物阑尾化脓性骨骺炎的MRI表现尚未见报道。马的化脓性关节炎和骨髓炎的MRI表现已有描述，有人提出使用MRI作为X线片的替代诊断方法，以便更早地进行诊断和治疗。由于MRI在评估软组织受累情况时准确性更高，因此在人类医学中也常规用于诊断骨髓炎。在此描述的一例5月龄雄性拳师犬病例中，X线片提示为化脓性骨骺炎诊断，尽管根据病史和体格检查结果进行了MRI检查以排除跛行的神经病因。MRI发现一个与骨骺相通的液腔。随后通过超声引导下对MRI上所见的与骨骺相通的液腔进行细针穿刺抽吸，确诊为化脓性骨骺炎。
