Patient
female, 83 year(s)
 
 
  • Figure 1
    Abdominal X-ray

    Radiolucent mass in the pelvis. Bone structures (short red arrow) and mural calcifications (red arrow).

     
    Area of Interest: Emergency; Imaging Technique: Conventional radiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Acute;
     
     
  • Figure 2
    Pelvic ultrasound image

    Complex cystic adnexal mass.

     
    Area of Interest: Emergency; Imaging Technique: Ultrasound; Procedure: Complications; Special Focus: Acute;
     
     
  • Figure 3
    Contrast-enhanced CT
     

    Sagittal view. Gravity-dependent levels secondary to the presence of different fluid densities. Calcified protuberance (arrow head- Rokitansky nodule).

     
    Area of Interest: Emergency; Imaging Technique: CT; Procedure: Complications; Special Focus: Acute;

    Axial view. Calcic images (teeth) outside the mass in the pelvis (red arrow).

     
    Area of Interest: Emergency; Imaging Technique: CT; Procedure: Complications; Special Focus: Acute;

    Axial view. Floating areas of fat attenuation around the liver. Do not confuse with pneumoperitoneum bubbles.

     
    Area of Interest: Emergency; Imaging Technique: CT; Procedure: Complications; Special Focus: Acute;

    Coronal view. Ascites, slight deviation of the uterus and signs of periuterine vascular engorgement.

     
    Area of Interest: Emergency; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Acute;
     
     
  • Figure 4
    Anatomopathological study
     

    Macroscopic view (H&E stain 2X). Vascular congestion in the fallopian tube, transmural necrosis and malignant squamous cells infiltrating the cyst wall.

     
    Area of Interest: Anatomy; Imaging Technique: Image manipulation / Reconstruction; Procedure: Surgery; Special Focus: Acute;

    Immunohistochemistry. Ki67: keratinizing squamous carcinoma with high proliferation rate.
