spigelian spi·ge·li·an (spī-jē'lē-ən)
Relating to or described by Flemish botanist and anatomist Adrian van der Spieghel (1578-1625).
The spigelian lobe cannot be overlooked in its entire extent until the liver is removed from the body and regarded from behind.
In this way a species of recess (spigelian recess or hepatic antrum of lesser sac) is formed.
Ventral: Visceral peritoneum investing the spigelian lobe and the gastro-hepatic omentum.
Between the two folds the caudal margin of the spigelian lobe projects into the lesser cavity.
Garrod, however, mentions the unusually large size of the spigelian lobe of the liver.
In addition to these, two other divisions are often to be seen—the spigelian and the caudate lobe.
The caecum when short has no longitudinal bands; the liver has a spigelian lobe.
