The following images represent an interesting case of congenital Cytomegalovirus infection.

 

Case report

 

A 33-year-old patient G0P0 was referred to our unit for the ultrasound examination at 20 weeks of the otherwise uncomplicated pregnancy. Patient underwent bariatric surgery for morbid obesity 5 years ago and has suffered from chronic anemia since. Her family history was negative. Her blood group was 0 Rhesus negative and her indirect Coombs test was negative.  No flu-like symptoms in the past months. The ultrasound screening at 12 weeks was normal.

 

During the ultrasound examination we revealed the following findings:

    • Ascites
    • Fluid collection, suspicious of hematoma, subsequent ventriculomegaly
    • Intestinal distention with echogenic bowel
    • Hepatomegaly with calcifications


The findings were suggestive of a fetal infection. We decided to perform a cordocentesis and amniocentesis to exclude parvovirus B19 and CMV (cytomegalovirus) infection.
Fetal MRI reported supratentorial tumor with ventriculomegaly which could be caused by intracranial bleeding.
Subsequent ultrasound performed in 2 weeks revealed worsening of the fetal condition, progression of ventriculomegaly and ascites.
The fetal blood results confirmed a congenital Cytomegalovirus infection.
The couple opted for the pregnancy termination due to an adverse prognosis for the fetus. The autopsy confirmed a severe systemic CMV infection.

 

Images 1,2,3: Images show fetal brain at 20 weeks, note echogenic lesion in the frontal lobe.

 

 

 

 

Images 3,4: Images show an axial plain view of the brain at 22 weeks, note the ventriculomegaly.

 

 

 

Images 5,6: Axial view of the brain, note apparent ventriculomegaly and echogenic round lesion in the frontal region.

 

 

 

Images 7,8: The images show the echogenic bowel and ascites, indicated by (*). 

 

  

 

Images 9, 10: The images show a transverse view of the fetal abdomen. Image 10 shows a hepatic calcification, indicated by arrow and the ascites, indicated by (*) . 

 

  

 

Images 11,12: Image 11 shows a transvers view of the abdomen with the apparent hepatomegaly indicated by the arrow. Image 12 shows a longitudinal view, hepatomegaly with calcification (indicated by arrows), ascites and the echogenic bowel.  

 

  

 

Images 13,14: Image 13 shows a cell infefcted by CMV, note intranuclear and intracytoplasmic inclusion and white halo around the nucleus. Image 14 shows a fetus after the pregnancy termination.
