Abstract

A 64-year-old man was referred to our department after a small pancreatic cystic lesion was discovered on computed tomography performed to assess choledocholithiasis. Multiple standard imaging modalities, including endoscopic ultrasound (EUS), failed to reveal pancreatic masses, wall thickening, or mural nodules. Consequently, a benign pancreatic cystic lesion was suspected, and the patient underwent biannual imaging studies including rotating magnetic resonance imaging and EUS. Six years after the initial detection of the pancreatic cyst, wall thickening was observed, leading to a shortened observation period of once every 3 months. After 6.5 years, hypoechoic area surrounding the cyst, which could be interpreted as thickening of the cyst wall was observed, prompting distal pancreatectomy due to the suspicion of malignant disease. The histopathological examination revealed a unilocular mucinous cyst with a single layer of cuboidal cells and low-grade dysplasia. A fibrous proliferation of the polycystic stroma and no ovarian-type stroma was observed. Malignant cells were absent from the cystic epithelium and stroma. The final histopathological diagnosis was a simple mucinous cyst of the pancreatic tail.

随访期间单纯粘液囊肿形态变化的调查:病例报告。
一名 64 岁的男性在评估胆总管结石时通过计算机断层扫描发现了一个小的胰腺囊性病变,随后被转诊到我科。包括内镜超声(EUS)在内的多种标准成像方式均未能发现胰腺肿块、壁增厚或壁层结节。因此,患者被怀疑是胰腺良性囊性病变,并接受了一年两次的成像检查,包括旋转磁共振成像和 EUS。在首次发现胰腺囊肿六年后,观察到囊壁增厚,因此缩短了观察时间,每三个月观察一次。6.5 年后,观察到囊肿周围有低回声区,可解释为囊肿壁增厚,由于怀疑是恶性疾病,因此进行了胰腺远端切除术。组织病理学检查显示,这是一个单眼粘液性囊肿,内有单层立方体细胞和低度发育不良。多囊性基质纤维增生,未见卵巢型基质。囊性上皮和基质中没有恶性细胞。最终的组织病理学诊断为胰腺尾部单纯粘液性囊肿。
