Placentomegaly with acute chorionitis: case report

Objective

Placentomegaly is enlargement of placenta with 2 standard deviation from mean values. A placental thickness of > 40mm at term is associated with gestational diabetes, intra uterine infections and hydrops fetalis.

Case(s)

A 16-year-old women, gravidity 1 with 23 weeks pregnancy was reffered to as placentomegaly. Her blood type was A Rh positive. There was single, alive and anatomically normal fetus with 23 week biometric measurement in her ultrasonographical exam. Cervical dilation with 3cm and 80% effacement was found in clinical exam. Placental thickness was 6 cm and measured from cord insertion as a perpendicular to uterine wall. Placenta has occupied nearly whole part of uterine cavity and fetus located on one side because of placenta. She delivered a 530gr, male, dead fetus by spontaneous vaginal way. Acute chorionitis and fibrinoid necrosis were found in histo-pathological evaluation of placenta.
Placentomegaly might be result of hydrous fetalis, placental bleeding, eritroblastosis fetalis, intrauterine infections (e.g. syphilis), chromosomal abnormality, molar pregnancy, chorioangioma of placenta. Increased placental thickness was associated with maternal mortality and fetal anomaly furthermore ıt was a predictor for LGA infants. Placentomegaly was accompanied with acute chorionitis in our case. However exact etiology of acute chorionitis could not found.
