Gastrointestinal stromal tumours (GISTs) are solid tumours of the gastrointestinal tract, mostly found in the stomach and intestine. They rarely present as cystic lesions. A 74-year-old woman referred to the hepatopancreaticobiliary unit, with 3 months history of upper abdominal discomfort. Abdominal ultrasound scan showed a large cystic lesion in the epigastric region suggestive of a pancreatic pseudocyst. The CT-scan showed a 6.6×6×6.3 cm size cyst related to the pancreas and extending to the hepatogastric omentum. Endoscopic ultrasound (EUS) scan was suggestive of a pancreatic pseudocyst. Aspirated Cyst fluid via EUS showed benign cytology with normal amylase, lipase and tumour markers (CEA, CA-19.9 and CA-125). She was referred as a case of pancreatic pseudocyst. After surgical excision, the histopathology confirmed the presence GIST in the wall of the cystic lesion. The possibility of GIST should be kept in mind in the presence of unusual features of a cyst on abdominal imaging.
胃肠道间质瘤（GISTs）是胃肠道的实体瘤，大多发生于胃和小肠。它们很少表现为囊性病变。一名74岁女性因上腹部不适3个月转诊至肝胰胆科。腹部超声扫描显示上腹部有一个大的囊性病变，提示胰腺假性囊肿。CT扫描显示一个大小为6.6×6×6.3 cm的囊肿，与胰腺相关并延伸至肝胃网膜。内镜超声（EUS）扫描提示胰腺假性囊肿。通过EUS抽吸的囊液显示细胞学良性，淀粉酶、脂肪酶和肿瘤标志物（CEA、CA-19.9和CA-125）正常。她被诊断为胰腺假性囊肿。手术切除后，组织病理学证实囊性病变壁内存在GIST。腹部影像学检查发现囊肿有异常特征时，应考虑GIST的可能性。
