A 5 yr old female intact English setter with a 17 day history of a penetrating oropharyngeal wound was referred for cervical swelling and pain. Physical examination revealed swelling at the left lateral aspect of the cranial cervical region. Pain was elicited upon flexion, extension, and leftward movement of the neck. Neurologic deficits were not identified. Cervical ultrasonography showed a 0.4 cm × 2.3 cm linear, hyperechoic structure in the soft tissues ventrolateral to the first (C1) and second (C2) cervical vertebrae. MRI demonstrated a linear structure 2 cm in length adjacent to the cranial aspect of C2. The foreign material was isointense to hyperintense on precontrast T1-weighted images, isointense on postcontrast T1-weighted images, and hypointense on T2-weighted images relative to adjacent muscle. Abnormalities within the spinal canal were not identified. Upon surgical exploration, a reed foreign body was identified deep to the serratus ventralis muscle. The patient was normal on follow-up evaluations 4 wk postsurgically.
一只5岁未绝育的英国塞特犬，有17天的口咽贯通伤病史，因颈部肿胀和疼痛前来就诊。体格检查发现颅颈区左侧肿胀。颈部屈伸及向左活动时引发疼痛。未发现神经功能缺损。颈部超声显示在第一颈椎（C1）和第二颈椎（C2）腹外侧的软组织中有一个0.4厘米×2.3厘米的线性高回声结构。磁共振成像（MRI）显示在C2颅侧有一个2厘米长的线性结构。相对于相邻肌肉，该异物在对比前T1加权图像上呈等信号至高信号，在对比后T1加权图像上呈等信号，在T2加权图像上呈低信号。未发现椎管内异常。手术探查时，在腹侧锯肌深部发现一根芦苇异物。术后4周随访评估时，该犬情况正常。
