A 21-year-old male with Groove Pancreatitis. Longitudinal view of the Gray-scale ultrasound demonstrates an ill-defined hypoechoic lesion (yellow arrow) in the groove between the head of the pancreas (P) and the second part of the duodenum (D2) suggestive of paraduodenal pancreatitis.

A hypoechoic lesion was noted in the space bounded by the pancreatic head and duodenum wall, which showed no vascularity on color Doppler [Figure 1].
A 21-year-old male with Groove Pancreatitis. Longitudinal view of the Gray-scale ultrasound demonstrates an Ill-defined cystic component (white arrow) around the of 2nd part of the duodenum (red arrow) compresses the lumen of the duodenum.
