摘　　要：BACKGROUND Patients with foreign bodies in the digestive tract are often encountered,but complete penetration of a foreign body through the gastrointestinal tract is rare,and the choice of imaging method is very important.Improper selection may lead to missed diagnosis or misdiagnosis.CASE SUMMARY An 81-year-old man was diagnosed as having a liver malignancy after he took magnetic resonance imaging and positron emission tomography/computed tomography(CT)examinations.The pain improved after the patient accepted gamma knife treatment.However,he was admitted to our hospital 2 mo later due to fever and abdominal pain.This time,he received a contrast-enhanced CT scan,which showed fish-boon-like foreign bodies in the liver with peripheral abscess formation,then he went to the superior hospital for surgery.It lasted for more than 2 mo from the onset of the disease to the surgical treatment.A 43-year-old woman with a 1 mo history of a perianal mass with no obvious pain or discomfort was diagnosed as having an anal fistula with the formation of a local small abscess cavity.Clinical perianal abscess surgery was performed,and fish bone foreign body was found in perianal soft tissue during the operation.CONCLUSION For patients with pain symptoms,the possibility of foreign body perforation should be considered.Magnetic resonance imaging is not comprehensive and that a plain computed tomography scan of the pain area is necessary.
