A Rare Anomalous Case of Absence

A rare anomaly, in which the celiac artery was not present, that is, the left gastric, the splenic and the common hepatic arteries arose independently from the abdominal aorta in that order, was found in an 80-year-old Japanese female among cadavers for student dissection. Such a case was not described in Adachi's classification (1928) of the variations of the celiac artery, but seemed to belong to type V of Morita's classification (1935). This type was a rare, valuable and embryologically primitive pattern, which was suggested by Morita as typus primitivus, and has been reported a few times.
