It may be present as subtle or vague abdominal pain following mid-gut volvulus. Computerized tomography may help diagnosis, but surgery remains the gold standard of diagnosis and treatment.</span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Case Presentation: </span></i></b>We presented a 24-year-old woman who complained of chronic intermittent abdominal pain, progressive food intolerance, and severe weight loss. Magnetic resonance enterography revealed dilated jejunum and collapsed ileum with slight bowel rotation around its mesentery (whirlpool sign), which was suggestive for mal-rotation of the intestine complicated by midgut volvulus, then the diagnosis was confirmed by laparotomy. During six months of follow-up after surgery, the patient&#39;s appetite improved significantly with eight kilograms of weight gain and resolution of abdominal pain.</span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Conclusion:</span></i></b> It may be a rationale to consider intestinal malformation as a differential diagnosis in a patient who complained of chronic abdominal pain with progressive weight loss, anorexia, and recurrent bowel obstructive symptoms.<b><i><span style="color:#0033cc"></span></i></b></span></span></span> Midgut Malrotation, Volvulus, Adult, Congenital Abnormalities, Case Report 380 385 http://caspjim.com/browse.php?a_code=A-10-2414-2&slc_lang=en&sid=1 Abdolreza Emami emami.abdoulreza@gmail.com 100319475328460041907 100319475328460041907 No Student Research Committee, School of Medicine, Babol University of Medical Sciences, Babol, IR Iran Yasser Asghari yasser_asghari@yahoo.com 100319475328460041908 100319475328460041908 No Department of Surgery, School of Medicine, Shahid Beheshti Hospital, Babol University of Medical Sciences, Babol, IR Iran Hasan Abedi Valukalaei h.abedi@mubabol.ac.ir 100319475328460041909 100319475328460041909 Yes Department of Internal Medicine, School of Medicine, Babol University of Medical Sciences, Babol, IR Iran Mohammad Sakhaei yaghobsakhaei@yahoo.com 100319475328460041910 100319475328460041910 No Islamic Azad University Sari Branch, Sari Campus, Iran
