CaseHPOFreeText: Admitted with long-standing dyspepsia and pancreatic cysts detected by ultrasound examination. There were no other symptoms, such as abdominal pain, weight loss, visual or hearing changes, headache or urinary complaints. The past medical and family histories were not of significance. There were no abnormal findings on examination.CT scan showed an enlargement of the pancreas, especially in the cephalic region, with heterogeneous density due to the presence of multiple hypodense nodules dispersed throughout the parenchyma. Abdominal MRI revealed several cysts. Endosonography that confirmed the presence of multiple simple cysts throughout the entirety of the pancreas as well as cysts in the left kidney and in the spleen. The findings described were compatible with simple cysts and pancreatic serous cystadenomas.

CaseNotHPOFreeText: MRI of the brain and entire spine and no hemangioblastomas were detected. Abdominal MRI scan excluded renal carcinoma.The plasma and urinary catecholamines and the urinary vanilmandelic acid were normal, excluding pheochromocytoma. Examination of the retina and ear, nose and throat, including audiometry excluded angiomas of the retina and endolymphatic sac tumors, respectively.
