The patient has had three prior pregnancies, all of which ended in miscarriages during the first trimester. She currently has monthly menstrual periods. Past medical history is unremarkable. The patient is an avid runner and takes part in several marathons each year. Temperature is 37.2\u00b0C (99.0\u00b0F), blood pressure is 115\/78 mmHg, pulse is 72\/min, and body mass index is 21 kg\/m2. Speculum examination reveals a normal-appearing cervix. The abdomen is soft and non-distended, and there are no palpable masses. The remainder of the physical examination is unremarkable. Laboratory testing reveals a prothrombin time of 12 seconds and a partial thromboplastin time of 37 seconds. A hysterosalpingogram is performed and shown below.

Complete failure of M\u00fcllerian duct fusion<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Incorrect:<\/strong>&nbsp;Uterus didelphys occurs when there&#8217;s complete failure in fusion of the M\u00fcllerian ducts. As a result, individuals will have two uteruses, two cervixes, and two vaginas. In contrast, this patient\u2019s imaging demonstrates a single vagina and cervix but two uteruses, which is more suggestive of a bicornuate uterus.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"B_Proliferation_of_benign_uterine_smooth_muscle_tumors\"><\/span><strong>B.&nbsp;<\/strong>Proliferation of benign uterine smooth muscle tumors<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Incorrect:&nbsp;<\/strong>Uterine fibroids are caused by benign proliferation of smooth muscle. The condition can lead to recurrent miscarriages. However, fibroids are neither present on physical examination nor imaging, and the patient lacks additional symptoms suggestive of fibroids (e.g., menorrhagia, back pain).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"C_Formation_of_anti-%CE%B22_glycoprotein_autoantibodies\"><\/span>C. Formation of anti-\u03b22&nbsp;glycoprotein autoantibodies<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Incorrect:<\/strong>&nbsp;Individuals with antiphospholipid syndrome can form anti-\u03b22&nbsp;glycoprotein autoantibodies and are at risk for recurrent miscarriages. The condition will lead to an elevated partial thromboplastin time (PTT). In contrast, this patient\u2019s PTT is within normal limits, making antiphospholipid syndrome unlikely.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"E_Reduced_hypothalamic_hormone_release\"><\/span>E. Reduced hypothalamic hormone release<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"margin: 0px;padding: 0px\"><strong>Incorrect:&nbsp;<\/strong>Excessive exercise can lead to reduced hypothalamic secretion of GnRH, which subsequently impairs pituitary release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH).<\/span> The condition can manifest with amenorrhea and infertility. While this patient has a history of training for marathons, her BMI is within normal limits, and she has been having monthly menstrual periods. Furthermore, imaging findings are more suggestive of a uterine abnormality as the underlying cause of her prior miscarriages.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Main_Explanation\"><\/span>Main Explanation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This patient has a history of recurrent miscarriages. Laboratory testing is unremarkable, and imagining reveals a&nbsp;<strong>bicornuate uterus<\/strong>. This condition arises due to&nbsp;<strong>incomplete fusion of the M\u00fcllerian ducts<\/strong>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Uterine anomalies<\/strong>&nbsp;describe anatomical malformations of the uterus that are present at birth.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A&nbsp;<strong>septate uterus<\/strong>&nbsp;occurs when the M\u00fcllerian ducts fuse, but the&nbsp;<strong>septum between the ducts persists<\/strong>. The condition can lead to decreased fertility and an increased risk of early miscarriage or pregnancy loss. Diagnosis can be made with&nbsp;<strong>imaging techniques<\/strong>&nbsp;(e.g., ultrasound, hysterosalpingogram, MRI) revealing the presence of a midline septum.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A&nbsp;<strong>bicornuate uterus<\/strong>&nbsp;occurs due to&nbsp;<strong>incomplete fusion of the M\u00fcllerian ducts<\/strong>. As a result, the uterus develops two upper horns above the uterine body, giving it a heart shape. The finding can be observed on imaging. The condition can lead to an increased risk of complicated pregnancy, fetal malpresentation, early miscarriage, and preterm birth.&nbsp;Finally,&nbsp;<strong>uterus didelphys<\/strong>&nbsp;occurs due to&nbsp;<strong>complete failure of M\u00fcllerian duct fusion<\/strong>. As a result, patients will have a double uterus, double cervix, and double vagina. While pregnancy remains possible, patients are at increased risk of early miscarriage and preterm birth. Imaging will reveal two uncommunicated uteruses, each one with its own fallopian tube.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"848\" height=\"666\" src=\"https:\/\/www.osmosis.org\/blog\/wp-content\/uploads\/sites\/2\/2024\/09\/uterine-abnormalities.png\" alt=\"illustration of uterine abnormalities\" class=\"wp-image-620\" srcset=\"https:\/\/www.osmosis.org\/blog\/wp-content\/uploads\/sites\/2\/2024\/09\/uterine-abnormalities.png 848w, https:\/\/www.osmosis.org\/blog\/wp-content\/uploads\/sites\/2\/2024\/09\/uterine-abnormalities.png?resize=300,236 300w, https:\/\/www.osmosis.org\/blog\/wp-content\/uploads\/sites\/2\/2024\/09\/uterine-abnormalities.png?resize=768,603 768w\" sizes=\"auto, (max-width: 848px) 100vw, 848px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Major_Takeaway\"><\/span>Major Takeaway<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Uterine anomalies include&nbsp;<strong>septate uterus, bicornuate uterus, and uterus didelphys<\/strong>.
