ABSTRACTObjective: To describe the case of a female patient with a saccular aneurysm of the abdominal aorta simulating a pancreatic pseudocyst.
Setting: Third level health care hospital.
Description of the case: A female patient, 59 years old, with grade II obesity, without chronic-degenerating diseases, with antecedents of abdominal pain for the last 10 years. She started with pungent-type pain at the epigastrium, accompanied by nausea and vomit; these symptoms conditioned her hospitalization, diagnosing a neoplasia of the pancreas. At admission she presented these symptoms, and a 10 kg weight loss. Study protocol was started; clinically without alterations, ultrasonography and computerized axial tomography were performed, revealing the presence of a pseudocyst in the pancreas. Since no clinical patterns of a specific pathology were encountered, an exploratory laparoscopy was performed, during which a saccular aneurysm of the suprarenal abdominal aorta was found, it was resected successfully. The patient was discharged from the hospital after 10 days. The histopathological report confirmed the diagnosis, associating it to an atherosclerotic origin.
Conclusion: Only 5% of the abdominal aorta aneurysms are suprarenal, and less than 5% present a saccular shape, associating them more frequently with an infectious origin. Although they are infrequent, cysts of extra-pancreatic origin must always be taken into account.
