What does left ovarian cyst 4641 mean?

Left ovarian cyst 4641 usually refers to the size of the left ovarian cyst in the ultrasound examination report as 46 × 41 mm. Ovarian cysts are cystic structures formed in the ovary. Most are benign and may be related to physiological changes or pathological factors.

1.Physiological cyst

Physiological ovarian cysts are common in women of childbearing age, such as corpus luteum cysts or follicular cysts, and are usually related to the menstrual cycle. The diameter of such cysts is mostly 2-5 cm, and some can reach 7-8 cm, but the 46×41 mm cyst exceeds the physiological range. Most physiological cysts can disappear on their own. It is recommended to review the ultrasound after menstruation.

2. Endometriosis cyst

Chocolate cysts are pathological cysts and are related to endometriosis. There is old blood accumulation in the cyst, and ultrasound often shows thick cyst wall and uneven internal echo. Patients may have dysmenorrhea, dyspareunia, or infertility and need to undergo tumor marker CA125 testing combined with imaging evaluation. Treatment options include gestrinone capsules or goserelin sustained-release implants. Larger cysts require laparoscopic surgery.

3. Serous cystadenoma

A common type of epithelial ovarian tumor, the cyst is thin-walled and contains clear fluid. A cystadenoma measuring 46 x 41 mm may compress the bladder or rectum, causing frequent urination or constipation. Ultrasound can show single-room or multi-room anechoic areas, and the tumor marker HE4 needs to be monitored. If the cyst grows rapidly or has solid components, the possibility of malignancy needs to be ruled out, and laparoscopic cyst removal should be performed if necessary.

4. Teratoma

Mature teratomas are germ cell tumors, and the cysts may contain tissue such as oil and hair. The ultrasound characteristics are mixed echo with strong light group. The 46×41 mm teratoma may have pedicle torsion and cause acute abdomen. It is recommended to undergo laparoscopic surgery as soon as possible after diagnosis, and ovarian tissue can be preserved in young patients.

5. Malignant tumors

Rarely, a solid cystic mass measuring 46 × 41 mm may represent a borderline or malignant ovarian tumor. If ultrasound shows papillary protrusions, abundant blood flow, or is accompanied by ascites or significantly elevated CA125, further evaluation with enhanced CT or MRI is required. Diagnosis requires pathological examination, and treatment is mainly based on comprehensive staged surgery.

After the discovery of a 46 × 41 mm left ovarian cyst, it is recommended to review the ultrasound every 3 months to monitor changes. Avoid strenuous exercise to prevent the cyst from rupturing or twisting. If abdominal pain worsens, seek medical attention immediately. Maintain a regular daily schedule and reduce the intake of high-estrogen foods. Women of childbearing age can take short-term contraceptive pills such as drospirenone and ethinylestradiol tablets to inhibit the growth of cysts, but all drug treatments must be carried out under the guidance of a gynecologist.
