Hypoglycemic Syndrome in a Patient with Proinsulin-Only Secreting Pancreatic Adenoma (Proinsulinoma)
Figure 1
Imaging studies and intraoperative appearance. (a) A contrast-enhanced computed tomography slice of the upper abdomen, showing a mildly hyperintense nodule, about 1 cm in diameter, located between the body and the tail of the pancreas (red arrow). (b) A gadolinium-enhanced magnetic resonance slice of the upper abdomen, showing a mildly hyperintense nodule, about 1 cm in diameter between the body and the tail of the pancreas (red arrow), in the same location as identified by CT. (c) A digital subtraction angiography with the catheter positioned in the proximal splenic artery, showing nodular vascularization from the arteria pancreatica magna (red arrow). (d) Isolation and enucleation of the adenoma using the CUGA Excel system. (e) Macroscopic appearance of the adenoma soon after resection (scale bar in cm).
