Ultrasound (Figure 1) revealed a large placental mass with mixed high and low echogenicity.
A subchorionic blood clot measuring 12 cm x 5 cm covered a large portion of the placenta and had well-defined margins on the fetal surface (shown by dotted lines).

Macroscopic examination revealed that a subchorionic blood clot measuring 12 x 5 cm covered a large percentage of the placenta with well-defined margins on the fetal surface (Figure 2).
Microscopic examination revealed an intervillous hematoma and fibrinous deposits directly beneath the chorionic plate with adjacent compressive effects (hematoxylin-eosin staining, 20x magnification).
