title: The posterior pararenal space: an escape route for retrocrural masses.
abstract: In two patients with retrocrural tumors, dissection of the tumors selectively into the posterior pararenal space was observed by computed tomography. Cadaver studies confirmed the presence of potential communications between the retrocrural space and the extrapleural space of the thorax or the posterior pararneal space of the abdomen.
