The transformation of uterine fibroids is common in relation to their development. Giant forms of cystic degeneration are rare. They raise diagnostic difficulties with other pelvic tumors, such as ovarian tumors and leiomyosarcomas. Magnetic resonance imaging specifies the original organ, the volume and the main relationships of fibromyoma with adjacent structures. The diagnosis of certainty is based on laparotomy coupled with histology. The authors illustrate these difficulties by observing a giant cystic degenerative fibroma in a 26-year-old G1P1 woman in the postpartum period.

Cyclopia is a rare congenital brain malformation frequently associated with facial anomalies. It is characterized by the presence of a single eye with varying degrees of doubling of the intrinsic ocular structures located in the middle of the face. It is the most severe facial expression of holoprosencephaly. Its aetiology is still poorly understood, but several factors could play a role in its occurrence, including certain viruses contracted during pregnancy. Obstetrical ultrasound has made antenatal diagnosis and the search for associated malformations possible. This diagnosis must be made antenatally because the prognosis is poor, hence the decision to terminate the pregnancy. We report a case of cyclopia associated with ambiguity of the external genitalia, discovered intraoperatively in a patient with poor prenatal follow-up, in whom a coronavirus infection (COVID-19) had been diagnosed in early pregnancy.

Rupture of a Rudimentary Uterine Horn: A Case Report

Pregnancy in an abnormal uterus is a high-risk situation in obstetrics. Uterus bicornis unicollis with a rudimentary horn is often discovered incidentally. The aim of this report is to warn obstetricians about recurrent abdominal pain in the second trimester of pregnancy without any cause identified. Pregnancy can proceed in the rudimentary horn. We presented a case of a rupture of the rudimentary horn which occurred at 25 weeks of amenorrhea in an unmarried 19-year-old primigravida. The rudimentary horn was removed after performing an emergency laparotomy for an intraperitoneal hemorrhage with signs of shock. This abnormality is often revealed by uterine rupture, which usually occurs in the second trimester of pregnancy. Conclusion: We emphasize the importance of early diagnosis of this uterine abnormality, before pregnancy if possible. Undiagnosed, this condition evolves towards uterine rupture during pregnancy and requires emergency surgery with excision of the rudimentary horn.
