A 39-year-old man presented with diplopia 1 day following left orbit trauma. CT scan and ultrasound showed a left trochlear hyperintensity that was interpreted by both the radiologist and echographer as a metallic foreign body. Surgical exploration failed to identify a foreign body. The patient presumably had preexisting trochlear calcification with a post-traumatic nonconcomitant small-angle vertical deviation and diplopia. Calcification should be considered in the differential diagnosis of trochlear hyperintensity noted on imaging studies.
一位 39 岁男性，左眼眶外伤后 1 天出现复视。CT 扫描和超声显示左侧滑车高信号，放射科医生和超声医生均将其解读为金属异物。手术探查未能发现异物。患者可能存在滑车钙化，外伤后出现非伴随性小角度垂直性偏斜和复视。在影像学检查中发现滑车高信号时，应考虑钙化作为鉴别诊断。
