Acute Gastric Volvulus on Hiatal Hernia.

The gastric volvulus is defined as an abnormal rotation of all or part of the stomach around one of its axes, creating the conditions of an upper abdominal obstruction with gastric dilation and risk of strangulation. It is a rare entity that requires a surgical treatment, and its diagnosis is often delayed due to frequently aspecific symptoms. We will describe the observation of a 62 year old patient who presented to the emergency department for acute epigastric pain with dyspnea.

Case note: retroperitoneal nonfunctioning paraganglioma.

Paragangliomas are extra-adrenal chromaffin tumours that develop at the expense of neuroectodermal cells of the autonomous nervous system. Retroperitoneal and nonfunctioning forms are very rare. They are often asymptomatic and can reach a substantial size.
