Clinically, ovarian hematomas are divided into four well recognized types: the large ovarian cysts with hemorrhagic contents due to twisting of the pedicle of the cyst or other conditions; the perforating hemorrhagic (chocolate) cysts of the ovary so well described by Sampson, and the follicular and corpus luteum cysts of the ovary which on their rupture may give rise to severe intraperitoneal hemorrhage.
The first type, as a rule, does not give rise to intraabdominal hemorrhage; the second type likewise gives rise to but little bleeding in the peritoneal cavity, since the perforation in the cyst becomes readily sealed by becoming adherent to the peritoneum of the pelvis or to the adjacent organ with which it comes in contact. It is therefore with the third and the fourth types, or the follicular and the corpus luteum cysts with rupture, causing intraperitoneal hemorrhage, that I wish to deal in this paper.
