En la ecografía guarda parecido con otras enfermedades placentarias y puede asociarse con distintos defectos y síndromes congénitos, pero también con fetos sin anomalías.  CASO CLÍNICO:  Paciente de 29 años, con antecedentes de 4 embarazos, dos cesáreas y un aborto. En el primer trimestre del embarazo se diagnosticó displasia mesenquimal placentaria que se evaluó con Doppler seriado de las arterias uterinas, umbilical y cerebral media. En virtud de tratarse de casos excepcionales se hace una breve revisión bibliográfica.  CONCLUSIONES:  La displasia mesenquimal placentaria tiene un amplio espectro de comportamiento clínico. Para los fetos sin anomalías no existen lineamientos claros acerca de su vigilancia. Se sugiere una evaluación seriada del bienestar fetal que incluya, pero no restrinja, la evaluación Doppler materno-fetal y registro cardiotocográfico, entre otras variables biofísicas, ya que tienen un riesgo elevado de óbito inexplicable.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  BACKGROUND:  Placental mesenchymal dysplasia (PMD) is a rare condition of recent description, often mistaken with other placental diseases. PMD is associated to fetal anomalies and syndromes. However, some fetuses are anatomically and genetically normal.  CLINICAL CASE:  Patient is 29 years old, with a history of 4 pregnancies, two cesarean sections and one abortion. In the first trimester of pregnancy, placental mesenchymal dysplasia was diagnosed and evaluated with serial Doppler of the uterine, umbilical and middle cerebral arteries. As these are exceptional cases, a brief bibliographic review is made.  CONCLUSIONS:  Placental mesenchymal dysplasia has a wide spectrum of clinical behavior. For fetuses without abnormalities there are no clear guidelines about fetal surveillance. We suggest a serial evaluation of fetal well-being that includes, but is not restricted to, maternal-fetal Doppler evaluation and cardiotocographic recording, among other biophysical variables, since they have a high risk of unexplained death.]]></p></abstract>
