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.
Chorionic hematoma is the pooling of blood between the chorion, a membrane surrounding the embryo, and the uterine wall. [2] It occurs in about 3.1% of all pregnancies , [ 2 ] it is the most common sonographic abnormality and the most common cause of first trimester bleeding .
These are postmentrual spotting, pain during menstrual bleeding, technical difficulty inserting the catheter during embryo transfer and secondary unexplained infertility combined with intrauterine fluid (fluid inside of the uterine cavity after the ovulation). Secondary symptoms are symptoms that are caused usually because of the primary symptoms.
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 ...
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.
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.
When the endometrial mucous membrane is found outside of the uterus in places such as the ovaries, it causes chronic pelvic pain with intercourse and menstrual cycles. Endometriomas can produce a toxic environment by producing estrogen, cytokines, interleukins, and other inflammatory substances, that could damage healthy endometriomal tissue.
Endometritis is inflammation of the inner lining of the uterus (endometrium). [6] Symptoms may include fever, lower abdominal pain, and abnormal vaginal bleeding or discharge. [1] [4] It is the most common cause of infection after childbirth. [7] [1] It is also part of spectrum of diseases that make up pelvic inflammatory disease. [8]
