However, in rare cases, these lesions can remain asymptomatic until adulthood. The combination of duplication cyst and pancreas divisum is extremely rare and both conditions have been linked with acute recurrent pancreatitis. We present the case of a 37 years-old patient who presented with repeated episodes of acute pancreatitis. By means of magnetic resonance imaging and endoscopic ultrasonography we discovered a duplication cyst whose cavity received drainage from the dorsal pancreas. After opening the cyst cavity to the duodenal lumen with a needle knife the patient presented no further episodes in the clinical follow-up. Comparable literature findings and therapeutic options for these abnormalities are discussed with regard to the presented case.enPáncreasPancreatitisHumanosEnfermedades DuodenalesEndosonografíaMasculinoImagen por Resonancia MagnéticaQuiste del ColédocoColangiografíaDuplication cystPancreas divisumAcute recurrent pancreatitisEndoscopic ultrasonographyMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Anatomy::Digestive System::PancreasMedical Subject Headings::Diseases::Pathological Conditions, Signs and Symptoms::Pathological Conditions, Anatomical::CystsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Imaging::Magnetic Resonance ImagingMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Imaging::Radiography::Radiography, Abdominal::CholangiographyMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Imaging::Ultrasonography::EndosonographyMedical Subject Headings::Publication Characteristics::Study Characteristics::Case Reportsresearch article21160764open access10.4253/wjge.v2.i9.318.1948-5190PMC2999032
