Fossa of Landzert

Last revised by Sonam Vadera on 24 Feb 2021

The fossa of Landzert is a congenital mesentery defect. It is present in about 2% of autopsy series and is formed due to non-fusion of the inferior mesentery to the parietal peritoneum. It is found to the left of the fourth part of the duodenum.

The inferior mesenteric vein runs along its (anterior) free edge.

History and etymology

It is named after Theodor Bernhard Landzert (1833-1889), a Russian anatomist.
