Ultrasonography of gastric volvulus: "peanut sign".
We report a case of chronic gastric volvulus in which ultrasonography (US) was useful. An 81-year-old woman was hospitalized due to vomiting, and upper gastroduodenoscopy revealed that the stomach was spirally twisted and constricted. An upper gastrointestinal barium study demonstrated an organoaxial-mesenteroaxial combined type gastric volvulus. US showed constriction between the dilated upper stomach body and the lower stomach body similar to a "peanut". Thereafter, the patient's vomiting stopped and follow-up US demonstrated that the constriction of the stomach was loosened. Therefore, we believe that this characteristic US sign paralleled the symptoms of the patient.
