Endoscopic retrograde cholangiopancreatography is a procedure commonly used for the diagnosis and treatment of various pancreatic and biliary diseases. Air embolism is a rare complication, which may be associated with this procedure. This condition can be manifested as cardiopulmonary instability and/or neurological symptoms. Known risk factors include: sphincterotomy; application of air with high intramural pressure; anatomic abnormalities; and chronic hepatobiliary inflammation. It is important for the health-care staff, including anesthesiologists, interventional gastroenterologists, and critical care specialists, amongst others, to promptly recognize air embolism and to initiate therapy in a timely fashion, thus preventing potentially fatal outcomes. We submit a brief review of the literature and a case report of air embolism which occurred in the immediate postoperative stage of an endoscopic retrograde cholangiopancreatography, performed in a woman with a history of liver transplantation due to Budd Chiari syndrome and biliary stricture.

Van Neck-Odelberg disease or ischiopubic osteochondritis, is a rare cause of pain in the pediatric pelvis due to late closure in synchondrosis ischiopubic, whose main symptom is an asymmetric pain that can cause a limitation in movement or limp. The different characteristics by images from simple radiography, computed tomography, MRI and bone scintigraphy scan will increase certainty diagnosis and will allow the correct differential diagnosis with fractures, posttraumatic osteolysis, infections or tumors, that leads to unnecessary invasive procedures, this being a benign disease with an evolution and improvement that occurs in weeks or months with conservative treatment. A case of a 15-year-old boy who consulted our hospital with an extra-institutional diagnosis of right ischiopubic fracture. After being evaluated by different imaging methods, a diagnosis of Van Neck-Odelberg or ischiopubic osteochondritis was made.
