“…[2] IPMNs can be classified as low-grade dysplasia, high-grade dysplasia, or associated invasive carcinoma. [10] Because of the variable risk of malignancy, it is important to predict the malignant potential of pancreatic IPMNs using imaging findings, as management differs based on malignancy risk. International consensus guidelines were established in 2006 [11] to aid in the management of pancreatic IPMN, and revised versions were established in 2012 [12] and 2017, [8] proposing high-risk stigmata and worrisome features, respectively, for determining the malignant potential of IPMNs.…”

Pancreatic serous cystic neoplasm mimicking intraductal papillary mucinous neoplasm: Two case reports and literature review

et al. 2023

Rationale: Serous cystic neoplasms (SCNs) are treated as benign lesions. It is widely known that SCN rarely have a connection with the main pancreatic duct (MPD), which helps differentiate them from other cystic lesions, such as intraductal papillary mucinous neoplasm (IPMN). However, very rare cases where the SCN appears connected to the MPD cause diagnostic confusion. Patient concerns: We present 2 patients with SCN (1 male, 54, and 1 female, 42). Both patients were asymptomatic, without abnormal laboratory results. Diagnosis: In both cases, abdominopelvic computed tomography and pancreatic magnetic resonance imaging scans revealed a multilobulated cystic lesion in communication with the MPD. Since the size of each patient’s lesion was >3 cm and there was connectivity with the MPD, it was strongly suspected to be a branch duct-type IPMN with worrisome features rather than SCN and surgical intervention was considered. Interventions: Both neoplasms were misdiagnosed as IPMN due to appearing connected with the MPD on radiologic imaging. Surgery was performed. Outcomes: A final diagnosis of microcystic serous cystadenoma of the pancreas without connectivity of MPD was confirmed in both patients. Lessons: An unnecessary surgery was performed due to atypical radiologic features in which the pancreatic duct seems to be connected to the pancreatic cystic lesion on magnetic resonance imaging, leading to misdiagnosis of SCN as IPMN. Particular attention should be paid to interpretation of clinicoradiologic findings of pancreatic cystic lesions, especially to the decision of surgical intervention. Also, awareness of presence of the atypical radiologic features of SCN may broaden the knowledge base of radiologists.

“…다중채널 CT, 내시경 초음파, 자기공명 담췌관조영술과 같은 영상 검사들은 췌장에 생기는 다양한 고형성 및 낭성 병변들의 감별 진단에 매우 중요한 역할을 담당한다. 예를 들면, 점액성 낭성 종양이나 고형성 가성유두상 종양 등은 특징적인 영상 소견들을 통해 췌장선암과의 감별이 비교적 용이하다( 3 ). 그러나, 포상세포암이나 신경초종 등의 희귀종양 및 자가면역 췌장염 또는 염증성 거짓종양과 같은 종양유사 병변들과 췌장선암의 감별 진단에 있어 영상 소견만으로 이들 질환을 정확히 구분하는 것은 어렵다.…”

Various types of tumors and tumor-like lesions may affect the pancreas. Among them, pancreatic ductal adenocarcinoma is the most common and is generally referred to as "pancreatic cancer." Recently, the detection rates of rare pancreatic tumors and tumor-like lesions have increased owing to technological advancements and increased frequency of imaging tests. Considering that rare pancreatic tumors and tumor-like lesions differ from pancreatic ductal adenocarcinoma in terms of the treatment plan and prognosis, the differential diagnosis of these diseases is clinically relevant. Various imaging tests play an important role in the differential diagnoses of rare tumors, such as acinar cell carcinoma and schwannoma, tumor-like lesions, such as autoimmune pancreatitis and inflammatory pseudotumor, and pancreatic ductal adenocarcinoma, but accurately distinguishing these diseases solely based on imaging findings is difficult. The aim of this pictorial review was to present the imaging findings of rare pancreatic tumors and tumor-like lesions and discuss important points for the differential diagnosis.
