Additionally, hematometra may develop as a complication of uterine or cervical surgery such as endometrial ablation, where scar tissue in the endometrium can "wall off" sections of endometrial glands and stroma causing blood to accumulate in the uterine cavity. [1] It can also develop after abortion, [4] as well as after childbirth.
Another theory is that hormonal changes that come with the menstrual cycle can cause blebs to spontaneously rupture. Blebs are small blisters/pustules filled with air or fluid and can develop on the lungs. [7] Endometrial tissue attaches within the thoracic cavity, forming chocolate-like cysts.
However, not all pelvic infections will cause distal tubal occlusion. Tubal tuberculosis is an uncommon cause of hydrosalpinx formation. While the cilia of the inner lining (endosalpinx) of the fallopian tube beat towards the uterus, tubal fluid is normally discharged via the fimbriated end into the peritoneal cavity from where it is cleared ...
In the early stages of infection, the ultrasound may appear normal. As the disease progresses, nonspecific findings can include free pelvic fluid, endometrial thickening, uterine cavity distension by fluid or gas. In some instances the borders of the uterus and ovaries appear indistinct.
The cause of thoracic endometriosis is unknown. [5] Those with previous surgeries are more prone to developing thoracic endometriosis due to the surgical manipulation that can cause embolisation of the endometrial tissue into the thoracic cavity. Some thoracic endometriosis patients have been described as having a congenital defect in the ...
Symptoms include vaginal bleeding, abdominal pain, premature labor and threatened miscarriage. [6] Ultrasonography is the preferred method of diagnosis. [7] A chorionic hematoma appears on ultrasound as a hypoechoic crescent adjacent to the gestational sac. The hematoma is considered small if it is under 20% of the size of the sac and large if ...
The myometrium is located between the endometrium (the inner layer of the uterine wall) and the serosa or perimetrium (the outer uterine layer).. The inner one-third of the myometrium (termed the junctional or sub-endometrial layer) appears to be derived from the Müllerian duct, while the outer, more predominant layer of the myometrium appears to originate from non-Müllerian tissue and is ...
Laparoscopic view, looking from superiorly to inferiorly in the peritoneal cavity which has been pumped up with carbon dioxide gas to visualize the uterus (marked by blue arrows). On the left fallopian tube there is an ectopic pregnancy and hematosalpinx (marked by red arrows). The right tube is normal. Specialty: Urology
