호산구성 췌장염은 매우 희귀한 질환으로 영상의학적 검사에서 췌장암과의 감별이 어려우나 췌장암과는 달리 스테로이드 치료와 같은 내과적인 치료로 호전되는 양성경과를 밟는다. 그러므로 췌장의 종양성 병변이 있는 경우 특히 췌장암 의심 환자에서 호산구증가증이나 호산구성 위장관염이 있는 경우 수술 전 생검을 고려할 필요가 있다.
Eosinophilic pancreatitis is a rare disorder that frequently accompanies peripheral eosinophilia and/or eosinophilic gastroenteritis. Eosinophilic pancreatitis can mimic a pancreatic neoplasm by forming a pancreatic mass with focal pancreatic eosinophilic infiltration. Because eosinophilic pancreatitis responds well to steroid treatment, it is important to distinguish eosinophilic pancreatitis from pancreatic neoplasm. Thus, fine needle aspiration biopsy (FNAB) should be considered in patients with a pancreatic mass accompanied by peripheral eosinophilia and/or eosinophilic gastroenteritis. We describe a case of eosinophilic pancreatitis with annular pancreas that was diagnosed by FNAB. This is the first reported case of eosinophilic pancreatitis with annular pancreas diagnosed by FNAB.
