Aim of the investigation is to precisely study the morphological features of ventral pancreas ductography in pancreas divisum, in order to improve the radiological interpretation and differential diagnosis of this frequent pancreatic anomaly. The clinical part of the study was based on 610 endoscopic retrograde pancreatograms, with pancreas divisum diagnosed in 14 (2.3%) cases; while the anatomical part consisted of 203 postmortem pancreatograms of human pancreas obtained at autopsy, where pancreas divisum was found in 12 (5.9%) cases. The following ductal features of the ventral pancreas were studied: length and calibre of the main duct, number of side branches, calibre of the common bile duct and the biliopancreatic junction angle. No significant differences were detected between the results from the 2 groups, with the exception of side branches, which were more numerous in the anatomical series, probably because of higher injection pressure and consequent better opacification. These results underline the potential of the anatomical pancreatography serving as a model for studying the ductal system of pancreas divisum.

The diagnosis of ovarian pregnancy is based on the improper rise of serum beta-hCG levels, sonographic findings of an empty uterus, highly characteristic ovarian formation with double hyperechogenic ring surrounding small hypoechogenic field, and the laparoscopic verification of Spiegelberg's criteria. We present a case of ovarian pregnancy in spontaneous cycle in 34-year-old woman following two unsuccessful IVF/ET procedures and ovarian pregnancy on contralateral side laparoscopically treated seven months ago, also achieved in non-stimulated, spontaneous cycle. On admission she had a serum hCG level of 596 mIU/mL on cycle day 46 and an empty uterus. Transvaginal sonography showed a 20 mm ring-like thick-walled hyperechogenic structure within the left ovary. The echogenic ring was surrounded by irregular, hypoechogenic structures suggestive of an ovarian pregnancy with periluteal hemorrhage and blood clots. The ruptured cystic ovarian pregnancy and the corpus luteum were removed by laparoscopy. During the procedure we have seen two clips on the fight ovary placed laparoscopically to achieve hemostasis after rupture of the ovarian pregnancy seven months ago. Histopathology showed isolated chorionic villi within hemorrhagic areas in the vicinity of the corpus luteum.
