What is pelvic effusion cyst?

Pelvic fluid effusion cyst is an ovarian tumor, which is a common gynecological disease in women. It has a wide age of onset. From the histological point of view, the tumor types are different, such as ovarian epithelial tumors, ovarian germ cell tumors, etc. It is not easy to be detected in the early stages, and we must be highly vigilant about the possibility of malignant transformation of the tumor. Let us now understand what pelvic fluid effusion tumor is.

Clinical manifestations

1. Benign ovarian tumor

In the early stages, the tumor is small and often asymptomatic, and is often discovered accidentally during a gynecological examination. When the tumor grows to medium size, there will be a feeling of abdominal distension or a mass with clear boundaries can be felt in the abdomen. Gynecological examination revealed spherical masses on one or both sides of the uterus, which were mostly cystic, with smooth surface, movable and no adhesion to the uterus. If the tumor grows large enough to fill the pelvis and abdominal cavity, compression symptoms will appear, such as frequent urination, constipation, shortness of breath, palpitations, etc. The abdomen is distended, the mass is poorly mobile, percussion is solid, and there is no mobile dullness.

2. Ovarian malignancy

There are no symptoms in the early stages and it can be detected during a gynecological examination. The main symptoms are abdominal distension, abdominal mass and ascites. The severity of the symptoms depends on the size and location of the tumor, the degree of invasion of adjacent organs, the histological type of the tumor, and the presence or absence of complications. In the late stage, cachexia symptoms such as weight loss and severe anemia may occur.

Differential Diagnosis

1. Ovarian malignancy

The disease usually has a short course and progresses rapidly. It is mostly bilateral, solid or cystic, irregular, and often accompanied by ascites. There may be weight loss and cachexia. B-ultrasound shows chaotic light clusters and spots in the liquid dark area with unclear boundaries. The blood flow is often abnormally rich. At the same time, tumor indicators such as CA125 may be elevated.

2. Benign tumors of ovarian origin

The most common are teratomas, serous cystadenomas, mucinous cystadenomas or simple cysts, which can be seen in any age. Physical examination may reveal an adnexal mass, and tumor markers are usually normal. Ultrasound examination may show that the mass is cystic or solid.

3. Pelvic inflammatory mass

She had a history of pelvic inflammatory disease, accompanied by abdominal pain, fever, increased leucorrhea and elevated blood count. Gynecological examination revealed palpable masses in the bilateral adnexal areas, which were fixed, immobile, and had unclear boundaries with the surrounding tissues. There is tenderness. The mass can be significantly reduced after anti-infection treatment.
