Pancreatic Laceration in a Pediatric Patient: An Unexpected Diagnosis

Magnetic resonance imaging glossary of findings of pediatric pancreatitis and the revised Atlanta classification

While still uncommon, the incidence of acute pancreatitis in children has been increasing over the last two decades. The Atlanta classification for acute pancreatitis, developed for adults, stratifies cases of acute pancreatitis based on imaging and clinical criteria. This classification scheme allows for standardized use of terminology to facilitate treatment and prognostication. Although US and CT should be used in critical or unstable patients, MRI is an ideal imaging modality in pediatric patients with acute pancreatitis because of its ability to characterize tissue without ionizing radiation. We review MRI examples specific to Atlanta classification terminology in pediatric patients. Chronic pancreatitis has also been increasingly diagnosed in children, and imaging plays a key role in the diagnosis and management of this insidious disease. MRI with magnetic resonance cholangiopancreatography is the optimal modality for assessing the pancreas in a child with known or suspected chronic pancreatitis because it provides tissue characterization and high-contrast imaging of the pancreatic duct without the use of invasive instrumentation or ionizing radiation. We also review and demonstrate accepted MRI findings of chronic pancreatitis.

The Pancreas in Child Abuse

The pancreas can be a critical indicator of inflicted injury in young children. Due to its retroperitoneal location and the amount of incursion of the abdomen required to cause injury, the pancreas is unlikely to be significantly injured in minor trauma incidents. Typical blunt force injury mechanisms for the pancreas include motor vehicle collisions, inflicted injury from blows or kicks, and bicycle handlebar injuries with deep incursion of the abdomen. The death of a toddler is described in which a pancreatic injury was a critical indicator of abusive injury rather than the claimed accidental fall or cardiopulmonary resuscitation-related trauma. Review of the medical literature regarding the epidemiology, etiology, and pathology of childhood pancreatic injuries is discussed. Pancreatic injury is a marker of severe blunt force trauma and should rouse a suspicion of nonaccidental trauma in young children. In the absence of a severe, high velocity or deep abdominal incursion traumatic mechanism, such as motor vehicle collision or bicycle handlebar injury, pancreatic laceration specifically is a marker of inflicted injury in children under the age of five.
