Occult micro-metastatic disease is common in PDAC, often undetected by current radiology techniques. Case. (A) At the time of diagnosis, a CT found 37 mm pancreatic head tumor (yellow arrows) contacting > 50% with the superior mesenteric vein (white arrow) with no liver metastasis (B) and classified as a resectable stage T3 N0 M0. In a CT performed just 4 weeks after the basal one, the pancreatic mass was stable (yellow arrows) (C), but liver metastases were found (red arrow) (D), the tumor re-staged as a T3 N0 M1, and the tumor surgical excision was not indicated anymore.
