Differential Diagnosis for a 26-year-old Woman with Recurrent Miscarriages, Cyclic Pain, Dyschezia, and Irregular Bowel Habits

  • Single most likely diagnosis:

    • Endometriosis: This condition is characterized by the presence of endometrial tissue outside the uterus, leading to cyclic pain, dyschezia (painful defecation), and irregular bowel habits, especially during menses. The history of recurrent miscarriages also supports this diagnosis, as endometriosis is known to affect fertility.

  • Other Likely diagnoses:

    • Adenomyosis: This condition involves the growth of endometrial tissue into the uterine wall, which can cause painful periods, heavy bleeding, and potentially contribute to miscarriages. However, the normal ultrasound findings might make this less likely.
    • Pelvic Inflammatory Disease (PID): Although PID can cause pelvic pain and infertility issues, the cyclic nature of the pain and the absence of other symptoms like abnormal vaginal discharge or fever make it less likely.
    • Irritable Bowel Syndrome (IBS): IBS could explain the irregular bowel habits but does not directly account for the cyclic pain or the history of miscarriages.

  • Do Not Miss diagnoses:

    • Ovarian Cancer: Although rare in young women, ovarian cancer can cause pelvic pain, irregular bowel habits, and infertility issues. It's crucial to rule out this diagnosis due to its severe implications.
    • Ectopic Pregnancy: Given the history of miscarriages, it's essential to consider the possibility of an ectopic pregnancy, especially if the patient is currently pregnant or suspects she might be. This is a medical emergency.

  • Rare diagnoses:

    • Mullerian Anomalies: These are congenital anomalies of the uterus and vagina that can increase the risk of miscarriage and may cause obstructive symptoms. However, a normal ultrasound of the uterus and ovaries makes this less likely.
    • Intestinal Endometriosis: A rare form of endometriosis where endometrial tissue grows into the intestines, causing bowel symptoms like dyschezia. This would be a rare cause of the patient's symptoms but could explain the combination of cyclic pain, dyschezia, and irregular bowel habits.
