    1. This case concerns a 35-year-old woman referred to our Gastroenterology Department 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.The patient underwent an abdominal computed tomography (CT) scan (Figure ​(Figure1),1), which 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. The majority of these lesions were small, but one larger contrast-enhancing lesion of 22 mm was present in the uncinate process.Open in a separate windowFigure 1Computed tomography abdominal scan. A: Small cystic lesions dispersed throughout the pancreas; B: The largest lesion.Given the findings of the CT scan, we performed an abdominal magnetic resonance imaging (MRI) (Figure ​(Figure2),2), which revealed several cysts that had a high signal intensity on T2 weighted images.Open in a separate windowFigure 2Magnetic resonance imaging. Cyst lesions are bright on T2-weighted images.The patient underwent endosonography that confirmed the presence of multiple simple cysts throughout the entirety of the pancreas. The majority of the cysts were less than 1 cm in diameter, but two cysts were larger than 1 cm. One of the larger cysts was 16 mm in diameter and was located at the isthmus-body transition. This cyst and did not communicate with the main pancreatic duct and was aspirated. The content had a serous appearance, and cytological analysis revealed amorphous material, few erythrocytes and inflammatory cells (Figure ​(Figure33).Open in a separate windowFigure 3Endosonography. A, B show a large cyst of 16 mm in diameter without communication or dilatation of the pancreatic duct; C: Demonstrates aspiration of the cyst; D: Demonstrates its appearance after total aspiration.The largest cyst was 23 mm in diameter and was located in the head of the pancreas. The cyst had a honeycomb appearance characteristic of serous cystadenomas (Figure ​(Figure4A).4A). The cytology did not show evidence of cellular atypia (Figure ​(Figure4B).4B). The carninoembryonic antigen was < 0.6 ng/dL, and the amylase in the cystic content was 135 U/L.Open in a separate windowFigure 4The largest cyst was 23 mm in diameter and was located in the head of the pancreas. A: Endosonography. Cyst with a honeycomb appearance; B: Cytology (papanicolaou stain, × 100). Benign pancreatic cysts.The endosonography also showed cysts in the left kidney and in the spleen (Figure ​(Figure5).5). The findings described were compatible with simple cysts and pancreatic serous cystadenomas and provided an indication for genetic testing for VHL. The sequencing of the VHL gene revealed one pathogenic heterozygous mutation in exon 1 (c.269A > T), confirming the diagnosis of VHL disease.Open in a separate windowFigure 5Endosonography. A: A cyst in the renal cortex; B: A cyst in the spleen.The patient underwent a MRI of the brain and entire spine and no hemangioblastomas were detected. The abdominal MRI scan excluded renal carcinoma. The plasma and urinary catecholamines and the urinary vanilmandelic acid were normal, excluding pheocromocytoma. The patient was also referred for examination of the retina and ear, nose and throat, including audiometry. There were no abnormal findings, which excluded angiomas of the retina and endolymphatic sac tumors, respectively.
