Sonographic features of agenesis of dorsal pancreas

Indian Journal of Radiology and Imaging, 2013
Agenesis of dorsal pancreas is an extremely rare congenital anomaly that occurs due to failure of the dorsal pancreatic bud to form the body and tail of the pancreas. We report the sonographic appearance of this condition in six cases.
