Spontaneous Rupture of Pyometra Causing Peritonitis in Elderly Female Diagnosed on Dynamic Transvaginal Ultrasound

Computed Tomography Findings in a Case of Uterine Rupture as a Complication of Pyometra

Uterine rupture in the setting of pyometra is a rare occasion, with an incidence of less than 0.5%. The clinical manifestation of a perforated pyometra is non-specific; therefore, it can mimic many other causes of acute abdomen, such as perforated viscus, acute appendicitis, or diverticulitis, which poses unique challenges to diagnosis solely based on clinical information. We reviewed a case of an elderly postmenopausal lady who presented with a sudden onset of generalized abdominal pain, preceded by fever and vomiting. Physical examination revealed a distended abdomen with clinical signs of peritonism. She was initially diagnosed with possible obstructed gastrointestinal carcinoma by clinical examination, with the differential diagnosis of diverticular abscess. Eventually, further abdominal and pelvic contrast-enhanced computed tomography (CECT) study revealed a pyometra with uterine rupture, complicated with pneumoretroperitoneum and pneumoperitoneum. This case emphasizes the value of a CT scan in establishing an accurate diagnosis and early detection of life-threatening complications, such as uterine rupture, as in this case.

Imaging evaluation of uterine perforation and rupture

Uterine perforation and rupture, denoting iatrogenic and non-iatrogenic uterine wall injury, respectively, are associated with substantial morbidity,and at times mortality. Diverse conditions can result in injury to both the gravid and the non-gravid uterus, and imaging plays a central role in diagnosis of such suspected cases. Ultrasound (US) is the initial imaging modality of choice, depicting the secondary signs associated with uterine wall injury and occasionally revealing the site of perforation. Computed tomography can be selectively used to complement US findings, to provide a more comprehensive picture, and to investigate complications beyond the reach of US, such as bowel injury. In certain scenarios, magnetic resonance imaging can be an important problem-solving tool as well. Finally, catheter angiography is a valuable tool with both diagnostic and therapeutic capability, with potential for fertility preservation. In this manuscript, we will highlight the clinical and imaging approach to uterine perforation and rupture, while emphasizing the value of various imaging modalities in this context. In addition, we will review the multi-modality imaging features of uterine perforation and rupture and will address the role of the radiologist as a crucial member of the management team. Finally, a summary diagrammatic depiction of imaging approach to patients presenting with uterine perforation or rupture is provided.

A Rare Case of Idiopathic Pyometra in a Premenopausal Patient

Pyometra is a very uncommon disease principally occurring in postmenopausal women. It is characterized by the accumulation of purulent material within the uterine cavity. This paper presents the clinical history of a 35-year-old premenopausal woman with otherwise normal menstruation who developed heavy menstruation and was diagnosed with a benign pyometra of indeterminate etiology in March 2017. The patient underwent repeated ultrasound-guided drainage, dilation and curettage, and antibiotic therapy. Biopsies of the pelvic sidewall revealed endometriosis in June 2017. The heavy menstruation and suppurative fluid in the uterus of the patient persisted in which intramuscular leuprolide acetate was prescribed to address the endometriosis and heavy menstrual bleeding. Ultimately, the leuprolide acetate effectively resolved the patient's bleeding and pyometra. The medication was concluded after 12 months of supervision and the patient is currently symptom free. Pyometra is an unusual condition rarely identified in premenopausal women. Drainage and antibiotic therapy are routinely employed; however, one may consider gonadotropin-releasing hormone agonist medication to potentially confer a beneficial patient outcome in rare cases where endometriosis and bleeding are intractable.
