“…Cystic islet cell tumors of the pancreas are rare and only 17 cases have been reported previously [1][2][3][4][5][6][7][8][9]. Most reports of cystic islet cell tumors emphasize the difficulties in achieving accurate diagnosis by only using radiographic findings.…”

“…About 10-15% are cystic neoplasms, classified as mucinous cystadenoma, mucinous cystadenocarcinoma, serous cystadenoma, papillary cystic tumor, and mucinous ductal ectasia [10]. To our knowledge, 17 cases of cystic islet cell tumors have been reported previously [1][2][3][4][5][6][7][8][9]. Most reports say that ultrasound, CT, and angiography are rarely helpful in distinguishing them from other cystic pancreatic lesions.…”

Cystic islet cell tumors: Radiologic findings in three cases

We report three cases of cystic islet cell tumors, two caused by gastrinomas and the other by an islet cell carcinoma. All three patients underwent computed tomography (CT) and angiography and two also had magnetic resonance (MR) imaging. Several common radiographic findings were present as follows: thickening of the cyst wall and irregularity of the inner surface on postcontrast CT and MR images, neovascularity and a densely staining hypervascular rim on angiography, and moderately increased signal intensity of the cyst content on T1-weighted MR images, which indicated fluid containing blood and/or necrotic tissue. These findings are helpful in defining the nature of these lesions and strongly suggest that cystic islet cell tumor should be included in the differential diagnosis.
