摘      要：We described the case of a peripancreatic paraganglioma(PGL)misdiagnosed as pancreatic *** exploration revealed an unremarkable pancreas and a large well-defined cystic mass originating at the mesocolon *** enucleation of the mass was performed,preserving the pancreatic ***,a diagnosis of PGL was ***,two previously unreported mutations,one affecting the KDR gene in exon 7 and another on the JAK3 gene in exon 4 were *** mutations are known to be *** and cytologic findings were blindly reviewed by an expert panel of clinicians,radiologists,and pathologists to identify possible causes of the *** major issue was lack of evidence of a cleavage plane from the pancreas at imaging,which prompted radiologists to establish an intraparenchymal *** blinded revision shifted the diagnosis towards an extrapancreatic lesion,as the pancreatic parenchyma showed no structural alterations and no dislocation of the Wirsung *** post,the identified biases were the emergency setting of the radiologic examination and the very thin mesocolon sheet,which hindered clear definition of the lesion *** endoscopic ultrasonography diagnosis was confirmed,emphasizing the intrinsic limit of this technique in detecting large ***,pathologic review favored a diagnosis of PGL due to the morphological features and immonohistochemical *** months after tumor excision,the patient is asymptomatic with no disease relapse evident by either radiology or laboratory *** report strongly highlights the difficulties in rendering an accurate preoperative diagnosis of PGL.
