Because of the increasing usage of lanthanum carbonate in dialysis patients, clinicians should be aware of its typical radiographic appearance.
A dialysis patient received a plain film and a computed tomography, both showing a "starry-sky" appearance in the nearly whole colon, and the radiological report mistakenly denoted it as barium.
The patient denied any exposure to barium or radiocontrast medium. Tracing back her medication history, lanthanum carbonate, 500 mg twice a day, has been prescribed for her hyperphosphatemia in recent 5 months.
Clinicians should be aware of typical radiographic appearance of lanthanum carbonate to avoid unnecessary management and may also take its radiopaque characteristic as an advantage to assess the patient's drug adherence.
由于碳酸镧在透析患者中的使用日益增加，临床医生应了解其典型的放射影像学表现。
一名透析患者接受了X线平片和计算机断层扫描，两者均显示几乎整个结肠呈“星空”样表现，放射学报告错误地将其认定为钡剂。
患者否认接触过钡剂或放射性造影剂。追溯其用药史，近5个月来一直为其高磷血症开具每日2次、每次500毫克的碳酸镧。
临床医生应了解碳酸镧的典型放射影像学表现，以避免不必要的处理，也可将其不透X线的特性作为评估患者药物依从性的一个优势。
