“…In non-humans, the Phrygian cap appearance has been reported in rhesus monkey and cat gallbladders [12,13]. To our knowledge, ours represents the first report of gallbladder imaging with a Phrygian cap appearance in a mouse.…”

We used live-animal magnetic resonance imaging (MRI) to examine the gallbladders of male mice. These healthy mice were fasted overnight before the study and anesthetized in an animal chamber, with a gas mixture of oxygen and isoflurane for small animal MRI. In the course of these live-animal MRI studies, we observed a Phrygian cap appearance to the gallbladder of one healthy-appearing 6-week-old male mouse, similar to that of the human gallbladder described in many reports. After euthanasia for measurement of bile content, this mouse’s gallbladder appeared anatomically normal. To our knowledge, this is the first report of a Phrygian cap appearance of the murine gallbladder.

“…I n a later section he discusses the anomaly of floating gallbladder and summarizes 50 cases of torsion reported up to 1930 (see below). Further cases of double gallbladder were reported by Wilson (1939)~ Bryan (1940), Golob and Kantor (I942), Kirkman (1946), Guyton (1946), Alexander (1947), Lockwood (1948), and others. Lockwood quotes Mentzer (1929)~ stating that it is " estimated that about 10 per cent of human beings have some anomaly of the biliary tract ".…”

(Boyden, '35 and McNamee, '35). OBSERVATIONSThe right and left bladders in our specimen were separate caudally to about the nornial position of the beginning of the cystic duct. It was a cesica fcllea divisn of the deeply cleft bilobed type (Boyden, 'as), and therefore one which had probably devcloped by a subdivision of the primary cystic diverticulum in the enibryo. The left bladder was oiily slightly larger than the right one. The cystic duct originated at the junction of two hepatic ducts, one of which came from the1atei.d edge of the right median lobe arid from the entire riglit laterul lobe; the other from most of the remainder of the liver. A small liepatic, or cysto-hepatic, duct eniptied into tlie cystic duct from the medial edge of the riglit median and caudate lobes.Tlie gallbladder normally lies in a deep fossa, the fossa ?-esica fcllccx, iii the right median lobe (fig. 3 ) . I n our spccimen tliere was u cleft in the liver a t this point which was deeper than normal, but slit-like. This cleft divided the lobe about lialf way to its base. Figure 1 makes it appear that the two bladders were widely separated, but in fact, the left bladder angled sharply toward tlie right bladder within the c c a c~e s s o r y '~ median liver lobe in such a way that the rim of liver tissue to the riglit of the left bladder was not over 5-6mm deep, arid the strip of tissue to the left of the right bladder was not more than 3-4mm deep. The riglit and left bladders were situated close to one another along the internal and inferior edges of the cleft. They were covered and held together by a tough sheet of peritoneum which appcarcd to dip into the space between the two bladders, separating them from one another.Roydcn ('26) stated that the occurreiice of accessory bladders is especially common in the cat (1 in S), although Kirkinail ( '46) cites personal correspondence from Hoyden wliicli indicates that cats in the Miiineapolis rcgion have fewer aecessory bladders than Boston's cat population ! The only gallbladder anomaly reported by Gribble ( '50) in approximately 900 speciniens which he examined was a single case of its total absence.* Of the nearly 2600 specimens examined by Boyden ("%), there were only 26 in which the primary and accessory vcsiclcs were of equal size. He made 110 meritiori of bladders in which the tips penetrated the liver tissue, but in a previous paper ('25, p. 157) he shows an iiitraliepatic bladdcr associated with the development of a 1)r. Gribl,le inforins mc that :L second specimen showing complete nbsenrc, of thr gallbladder wt'iis found after his n1:~anal had gone to press, and that he has noted srveral cases of complrtely intrahrpatic bladders in the cat. IIIVIDED INTRAIIEPATIC GALLBLADDER 717pancreatic bladder. The condition in which both parts of a divided bladder penetrate the liver tissue was considered rather rare, since it combined two anomalies. Of approximately 200 eats which my students have dissected over the past 5 years, no other specimen has shown a comparable condition, although...
