Internal abdominal hernias may rarely be the cause of intestinal obstruction with an incidence of less than 1% and paraduodenal hernias constitute approximately 50% of them. Those hernias emerge as a result of abnormalities in gut rotation at the embryonic stage. The clinical spectrum of a symptomatic internal hernia may range from abdominal pain to frank intestinal obstruction. Delay in the diagnosis and treatment should be avoided, since the content of paraduodenal hernia may quickly progress to strangulation and necrosis because of vascular compromise. Here, we report a case of successfully diagnosed and treated paraduodenal hernia who was admitted with symptoms of abdominal pain, nausea, vomiting, distension and obstipation. Key words: Internal hernia, paraduodenal hernia
