BACKGROUND Inferior vena cava (IVC) filters are indicated for patients with recurrent venous thrombosis despite proper anticoagulation or whenever anticoagulation is contraindicated. IVC filter deployment is an invasive procedure with various complications. One example is IVC filter limb fracture and migration, which is associated with significant morbidity and/or mortality. Extravascular migration toward pancreas may induce pancreatitis. Patients with chronic pancreatitis are known to have an increased risk of pancreatic malignancy. CASE REPORT We report an extremely rare case of IVC filter fractured limb in 44-year-old woman, which had migrated into the pancreatic tail and manifested as chronic distal pancreatitis. A pancreatic adenocarcinoma was found by biopsy at the pancreas tail. It is likely that a foreign body promoted this metaplasia and neoplastic transformation. CONCLUSIONS Early detection and retrieval of a displaced foreign body in organs, such as the pancreas, seem to be essential to reduce risk of subsequent complications, including chronic inflammation and possibly neoplasia.
下腔静脉（IVC）过滤器适用于尽管进行了适当抗凝治疗但仍有静脉血栓复发的患者，或在抗凝治疗禁忌的情况下使用。IVC 过滤器的植入是一种具有多种并发症的有创性手术。其中一个例子是 IVC 过滤器的分支断裂和迁移，这与严重的发病率和/或死亡率有关。向胰腺外迁移可能会引发胰腺炎。已知患有慢性胰腺炎的患者患胰腺恶性肿瘤的风险增加。
我们报告了一例极其罕见的 44 岁女性 IVC 过滤器分支断裂的病例，该过滤器已迁移至胰腺尾部并表现为慢性远端胰腺炎。胰腺尾部活检发现胰腺腺癌。很可能是异物促进了这种化生和肿瘤转化。
早期发现和取出在器官（如胰腺）中移位的异物，似乎对于降低随后发生的并发症（包括慢性炎症和可能的肿瘤）的风险至关重要。
