Background
The DP groove is a space delimited medially by the head of the pancreas and laterally by the second duodenal portion.
Its superior border is the duodenal bulb,
its anterior border is the first portion of the duodenum and sometimes the gastric antrum and the posterior border is the third duodenal portion and the inferior vena cava,
considering the segment intrapancreatic of the common bile duct as part of this limit.
Also in this location there are small lymph nodes that are not usually visualized by imaging techniques.
Therefore,
due to the wide spectrum of entities that may affect this region,
it is important to make a good diagnosis highlighting the role of imaging tests,
although it is sometimes necessary to appeal to a definitive histopathological study.
The pathologies that are originated or affect the groove can be divided into four types according to whether they affect the pancreas,
the duodenum,
the lymph nodes or the distal bile duct.
Among all of them we will focus on pancreatic pathologies due to the challenge that pose its accurate pretreatment diagnosis by imaging techniques in many cases.
