Differential Diagnosis for Rối Loạn Kinh Nguyệt (Menstrual Disorder) with Ovarian Cyst
- Single Most Likely Diagnosis
- Hội chứng buồng trứng đa nang (Polycystic Ovary Syndrome - PCOS): This condition is characterized by irregular menstrual cycles, cysts on the ovaries, and hormonal imbalance. The presence of a 22x18 mm cyst on the left ovary and a history of menstrual disorder for 1 year supports this diagnosis.
- Other Likely Diagnoses
- U xơ tử cung (Uterine Fibroids): Although not directly related to ovarian cysts, uterine fibroids can cause menstrual irregularities and are common in women of reproductive age.
- Rối loạn chức năng buồng trứng (Ovarian Dysfunction): This encompasses a range of disorders affecting ovulation, which could explain the menstrual irregularities and the presence of an ovarian cyst.
- Do Not Miss Diagnoses
- Ung thư buồng trứng (Ovarian Cancer): Although less likely, ovarian cancer can present with pelvic masses and irregular menstrual bleeding. It's crucial to rule out malignancy, especially in the presence of a significant ovarian cyst.
- Bệnh buồng trứng kén (Ovarian Endometrioma): Associated with endometriosis, these cysts can cause pelvic pain, menstrual irregularities, and infertility.
- Rare Diagnoses
- Hội chứng buồng trứng kháng androgen (Androgen Insensitivity Syndrome): A rare condition where an individual is genetically male but has resistance to male hormones, leading to female external appearance but with undescended testes and no uterus or ovaries.
- Bệnh Cushing (Cushing's Syndrome): A rare endocrine disorder caused by excess cortisol, which can lead to menstrual irregularities among other symptoms.
- Thyreotoxicosis (Hyperthyroidism): Although more commonly associated with weight loss and tremors, hyperthyroidism can also cause menstrual irregularities and should be considered in the differential diagnosis.
