Pancreatic cystic lesions are challenging clinically because they represent a spectrum of different lesions, ranging from benign to malignant. At times, the final diagnosis is made only at surgery. We report a final diagnosis of a pancreatic cystic lymphangioma, made using endoscopic ultrasound fine needle aspiration (EUS-FNA) in a young girl, with cytological examination and measurement of the level of triglycerides in the intracystic fluid.
A 6-year-old girl showed evidence of a pancreatic head cystic lesion on transabdominal ultrasonography. Magnetic resonance imaging (MRI) showed a multilobular cystic lesion, with an inverted C shape, around the splenomesenteric confluence ([Fig. 1]).
The MRI also showed a small, irregular area, which was suspected of being a solid component within the lesion. Endosonography with linear array showed a micro-macrocystic lesion, 4 cm in diameter, in the pancreatic head and uncinate process ([Figs. 2], [3]).
No solid mass was seen. EUS-FNA with a 22 G needle was carried out to evacuate the lesion. The intracystic fluid appeared milky and viscous ([Fig. 4]).
Intracystic fluid analysis showed amylase/lipase 200/1720 U/L, carcinoembryonic antigen (CEA) 0.2 ng/mL, and triglycerides 10 570 mg/dL. Cytology showed normal lymphocytes. The final diagnosis was pancreatic cystic lymphangioma. Abdominal ultrasound confirmed the presence of an unchanged lesion at 1 year follow-up and the patient remains asymptomatic.
Cystic lymphangioma of the pancreas is an extremely rare, benign tumor of lymphatic origin [1] [2]. Possible locations are in the retroperitoneum, within or outside the pancreas [3]. Histologically, it appears as a polycystic lesion, with the cysts separated by thin septa, and lined with endothelial cells. It can be difficult to distinguish this lesion from other pancreatic cystic lesions. A final diagnosis is often achievable only by histopathological examination of the resected lesion [1] [2] [3]. In cases of pancreatic cystic lymphangioma, EUS-FNA with cytological examination and measurement of the level of triglycerides in the intracystic fluid can provide a safe and accurate diagnosis [4] [5].
