“…These lesions appear as well-circumscribed, rounded, hypoechoic or mixed-echogenicity masses protruding from the fetal side of the placenta (46,50). Most are located near the cord insertion, and Doppler imaging reveals substantial vascularity or a large feeding vessel (46)(47)(48) (Fig 20).…”

The placenta is often overlooked in the routine evaluation of a normal gestation, receiving attention only when an abnormality is detected. Although uncommon, abnormalities of the placenta are important to recognize owing to the potential for maternal and fetal morbidity and mortality. Pathologic conditions of the placenta include placental causes of hemorrhage, gestational trophoblastic disease, retained products of conception, nontrophoblastic placental tumors, metastases, and cystic lesions. Sonography remains the imaging modality of choice for evaluation of the placenta. Magnetic resonance (MR) imaging can be of added diagnostic value when further characterization is required, particularly in the setting of invasive placental processes such as placenta accreta and gestational trophoblastic disease. Computed tomography (CT) has a limited role in the evaluation of placental disease owing to limited tissue characterization, compared with that of MR imaging, and the radiation risk to the fetus; this risk often outweighs the benefit. The primary role for CT is in the evaluation of trauma and gestational trophoblastic disease, for which it allows characterization of the primary lesion and distant metastases.

“…Chorioangiomas are the most common, occurring in less than 1% of pregnancies (46,47). Placental teratomas are extremely rare and are similar in appearance to chorioangiomas, but are differentiated by the presence of calcifi cations (46).…”

“…11 Some studies have found only arterial blood flow in chorioangiomas, 12,13 some have found only venous waveforms, 14 and a few studies have demonstrated both arterial and venous waveforms. 9 Doppler flow characteristics include either abundant blood flow or a single large feeding vessel within the tumor with a branching pattern.…”

“…Spontaneous abortion is characterised by degenerative changes on histology and small vesicles that are focal rather than diffuse in contrast to PMD 4. Placental chorioangioma has a well-circumscribed echogenic area with increased vascularity which may be seen as a protrusion on the fetal placental surface 6. This increased flow may lead to fetal congestive heart failure.…”

Placentomegaly and placental mesenchymal dysplasia

SUMMARYA 23-year-old primigravida presented to the labour ward at 37 weeks gestation referred with intrauterine growth restriction, oligohydramnios and placentomegaly. Differential diagnoses of placentomegaly were considered. Her antenatal blood screening tests were normal. There were no fetal malformations. However, triple screen and fetal karyotype were not done as patient presented late in pregnancy. The patient soon went into spontaneous labour and delivered a girl weighing 2.15 kg with a normal Apgar score. The cord was long and twisted; placenta was bulky, 1.7 kg, with prominent grape-like vesicles involving whole placenta with a rim of normal placenta at the periphery. Microscopy showed some areas of multiple villi with marked hydropic changes and myxoid degeneration, preserved vasculature and no trophoblastic proliferation. Placental mesenchymal dysplasia was thus diagnosed. The baby had no evidence of Beckwith-Wiedemann syndrome. The child is now 3 years old with normal development and is doing well. BACKGROUND

Role of color Doppler imaging in diagnosing and managing pregnancies complicated by placental chorioangioma

Abstract: Color Doppler imaging helps differentiate placental chorioangioma from other placental lesions and may be useful in the prenatal follow-up of chorioangioma.
