Pancreatic panniculitis (PP) is a necrotizing inflammation of subcutaneous fat that is a rare complication of pancreatic disease appearing in 2% to 3% of all patients. It is more common in the elderly and often affects the extremities. It presents as skin inflammation with pain and erythema nodules. We report a case of acute pancreatitis associated with PP in an old female. She was admitted for vomiting and abdominal pain for 3 days and presented with a 2-week history of erythematous subcutaneous nodules on her legs. Laboratory and ultrasonic findings revealed acute pancreatitis. High frequency ultrasound showed hypoechoic foci in subcutaneous soft tissue layer and adipose layer. Histopathological examination confirmed the diagnosis of PP. Nodules disappeared with the resolution of acute pancreatic inflammation. PP may be the first manifestation of pancreatic disease. Imaging features of this pathology are seldom described and ultrasonic diagnosis experience is worth to be accumulated.
胰腺性脂肪炎（PP）是一种罕见的胰腺疾病并发症，占所有患者的 2%至 3%，可导致皮下脂肪发生坏死性炎症。它多见于老年人，常累及四肢，表现为伴有疼痛和红斑结节的皮肤炎症。我们报告了一例老年女性急性胰腺炎合并胰腺性脂肪炎的病例。她因呕吐和腹痛 3 天入院，腿部出现红斑性皮下结节已有 2 周。实验室和超声检查结果显示为急性胰腺炎。高频超声显示皮下软组织层和脂肪层有低回声灶。组织病理学检查证实了胰腺性脂肪炎的诊断。随着急性胰腺炎的消退，结节消失。胰腺性脂肪炎可能是胰腺疾病的首发表现。这种病理的影像学特征很少被描述，超声诊断经验值得积累。
