1. To illustrate embryology and anatomy of peritoneum with emphasis on foramina, recesses & fossae associated & responsible for development of congenital internal hernias 2. To discuss salient imaging findings that can help in diagnosing and classifying internal hernias on multidetector computed tomography (MDCT) 3. To present an algorithmic approach for accurate preoperative diagnosis  

Congenital weakness in peritoneal orifices leads to abnormal protrusion of viscera & internal hernias. These patients can be asymptomatic or can present with epigastric discomfort, periumbilical pain and recurrent vomiting. Diagnosing it early is critical as internal hernia with small bowel obstruction (SBO) is at high risk for strangulation, ischemia and perforation. Accurate knowledge of anatomy of peritoneal cavity and potential hernia sites is very important. Each type of hernia has characteristic anatomic location & CT appearance. MDCT with multiplanar reconstruction (MPR) plays vital role in diagnosis & guiding surgical approach.  In this educational exhibit, we discuss the types and important imaging findings of paraduodenal, pericecal, foramen of Winslow, transmesenteric, transmesocolic, pelvic and supravesical, sigmoid mesocolon, transomental hernias with emphasis on utility of MDCT & algorithmic approach for accurate preoperative diagnosis.
