自身免疫性胰腺炎(AIP)是胰腺的炎症,通常以免疫球蛋白G(IgG)4水平升高为特征。对于有其他胰腺炎病因危险因素的患者,这种情况的诊断可能具有挑战性,需要采用临床综合方法,放射学,和实验室发现。这里,我们介绍了一例既往有多次酒精性胰腺炎住院史的患者,出现腹痛症状的人,恶心,和呕吐。计算机断层扫描(CT)成像显示腹内脓肿和与胰腺炎一致的发现。进一步的实验室结果显示脂肪酶和IgG4水平升高,表明AIP是根本原因。该病例强调了将AIP作为胰腺疾病患者的鉴别诊断的重要性。
Autoimmune pancreatitis (AIP) is an inflammatory condition of the pancreas, commonly characterized by elevated levels of immunoglobulin G (IgG) 4. Diagnosis of this condition can be challenging in patients with risk factors for other pancreatitis etiologies and requires a comprehensive approach utilizing clinical, radiologic, and laboratory findings. Here, we present a case of an individual with a history of multiple prior hospitalizations for alcoholic pancreatitis, who presented with symptoms of abdominal pain, nausea, and vomiting. Computed tomography (CT) imaging revealed intra-abdominal abscesses and findings consistent with pancreatitis. Further laboratory results revealed elevated lipase and IgG4 levels, indicating AIP as the underlying cause. This case highlights the importance of considering AIP as a differential diagnosis in individuals presenting with pancreatic disease.
