A 65 year-old man with anorexia, epigastric pain and weight loss # 2kilogram for one month but without nausea nor jaundice.
Abdomen ultrasound detected some metastase nodes in the liver that may come from the tail of the pancreas tumor.
A hypoechoic mass with peripheric Doppler signals at the spleen hilus # 35x29mm was revealed through the spleen window at the LUQ that leads to think about a pancreatic tail tumor.
Lab data was not any interesting clue for diagnosis.
MSCT confirmed a #30x40mm pancreas tumor of the pancreatic tail which captured CE irregularly, hypodensity lower than pancreatic tisue and metastase liver nodes #10-45mm.
Biopsy of metastases liver nodule was done. The result of the liver biopsy was a poor differentialized adenocarcinoma ; and immunohistostaining was an endocrinological pancreatic tumor.
Endocrinological pancreatic tumor is still a rare entity and hardly to diagnose as it could appear anywhere. It has to combine some modalities of the diagnostic imaging as the diversity and complexities of the endocrinological pancreatic tumor.
