[8] The cystic lymph node is situated at the neck of the gallbladder.
[2][4] It increases in size in cholecystitis and cholangitis;[citation needed] it becomes enlarged in most cases of acute cholecystitis which serendipitously also makes it easier to identify in case of subsequent surgery.
[citation needed] The node can be used as a landmark to prevend iatrogenic injury during surgery in the cystohepatic triangle so as to avoid the bile ducts and other structures of the porta hepatis.
[9] The node is named after Fred Bates Lund (1865-1950), an American surgeon.
It was also named after the Italian anatomist and physician, Paolo Mascagni (1752-1815), who first identified the node around 1787.
