“…Ruptured ovarian teratomas can be suspected when imaging shows discontinuity of the cyst wall, an irregular shape of the teratoma, extra-tumoral fatty nodules, and ascites. CT is the most sensitive technique for detecting intraperitoneal fatty nodules, which are commonly observed around the liver surface (Figure 9) [64,65].…”

In female patients, acute pelvic pain can be caused by gynaecological, gastrointestinal, and urinary tract pathologies. Due to the variety of diagnostic possibilities, the correct assessment of these patients may be challenging. The most frequent gynaecological causes of acute pelvic pain in non-pregnant women are pelvic inflammatory disease, ruptured ovarian cysts, ovarian torsion, and degeneration or torsion of uterine leiomyomas. On the other hand, spontaneous abortion, ectopic pregnancy, and placental disorders are the most frequent gynaecological entities to cause acute pelvic pain in pregnant patients. Ultrasound (US) is usually the first-line diagnostic technique because of its sensitivity across most common aetiologies and its lack of radiation exposure. Computed tomography (CT) may be performed if ultrasound findings are equivocal or if a gynaecologic disease is not initially suspected. Magnetic resonance imaging (MRI) is an extremely useful second-line technique for further characterisation after US or CT. This pictorial review aims to review the spectrum of gynaecological entities that may manifest as acute pelvic pain in the emergency department and to describe the imaging findings of these gynaecological conditions obtained with different imaging techniques.

“…The rate of malignant transformation is estimated to be between 1% and 3% and usually corresponds to postmenopausal women [ 4 ]. In addition, in rare cases, mature cystic teratomas may rupture [ 5 ]. In contrast, adnexal torsion with mature cystic teratoma is common [ 6 ].…”

Mature cystic teratomas are common benign ovarian tumors. They usually occur in young women, less than 40 years old. Our case report concerns a patient of perimenopausal age who came to the hospital complaining about mild abdominal pain, fever below 37.8°C, and diarrhea. The patient had an intrauterine contraceptive device inserted. Based on the clinical findings and imaging, a possible diagnosis of pelvic inflammatory disease was set, and intravenous administration of broad-spectrum antibiotics started immediately. The decision for performing laparotomy was taken after the fact that the clinical condition and blood tests of the patient had shown no improvement. Intraoperatively, the presence of a large twisted ovarian mass with signs of total necrosis due to adnexal torsion was detected. A histological examination of the surgical specimen confirmed the diagnosis of mature cystic teratoma in the right ovary. The postoperative course was uneventful. The presentation of the case follows a brief literature review of this rare medical condition regarding the diagnostic and therapeutic approach of these patients.

Rationale: Reports of mature cystic teratomas (MCTs) with associated complications and changes in serum cancer antigen levels are rare. Herein, we report a rare case of MCT with associated complications (rupture and malignant transformation), high levels of serum cancer antigens (CA19-9, CA12, and CEA), and surgical therapy. Patient concerns: An 81-year-old woman was referred to our emergency department because of diffuse abdominal pain and distension for 20 days. Diagnoses: Imaging findings, including transabdominal ultrasonography, computed tomography, and magnetic resonance imaging, revealed a complex solid cystic mass in the lower abdomen. Preoperative laboratory test results showed high levels of serum cancer antigens (CA19-9, CA12, and CEA) in MCT. Histopathological examination of the specimen revealed a MCT with rupture and malignant transformation. Interventions: The patient underwent a total abdominal hysterectomy, bilateral oophorectomy, and partial omentectomy. The patient did not undergo chemotherapy after surgery. Outcomes: The follow-up period was 12 months. The patient recovered well without focal local recurrence or distant metastasis after the surgery. Lessons: The study aims to report a new case of MCT with associated complications (rupture and malignant transformation) and changes in serum cancer antigen levels. Although this tumor presents as a complex solid cystic mass, detection of the intratumoral fat component is a key diagnostic imaging feature. A high level of serum cancer antigen may indicate the malignant transformation of MCT. In this case, surgery was an effective treatment for the MCT.
