A: Changes in the erythrocyte (RBC) counts of a broodmare during the periparturient
period. B: Changes in hemoglobin concentration (Hb) of the broodmare during the
periparturient period. C: Changes in packed cell volume (PCV) of the broodmare during
the periparturient period. D: Changes in the leukocyte (WBC) counts of the broodmare
during the periparturient period. Solid line indicates an affected mare. Dot lines
indicate three age-matched Thoroughbred broodmares controls without previous abnormal
breeding history. Values are expressed as the means +- SEM in controls.

Hb were found to be lowered as compared with the reference value and three age-matched Thoroughbred broodmares controls (Controls. 1-3) without previous abnormal breeding history (Figs. 1-A, -B, -C, -D), and no changes were observed in the periparturient period. Hence, hematologic findings of this case indicated mild anemia caused by hemorrhage. The PCV level was maintained within the range 33-39% for at least 3 weeks (Fig. 1-C).

The palpated hematoma mass was as large as a volleyball and located in the area adjacent to the right uterine horn (Fig. 2). Ultrasonographic examination on day 3 revealed a large hyperechoic mass measuring 20 x 15 cm, extending directly to the right uterine horn from the body of the uterus (Figs. 2, 3).
Ultrasonography performed on day 3 demonstrates a large hyperechoic mass, suggesting
hematoma. As shown in a schema of whole part of hematoma as large as volley ball
beside the right pregnant uterine horn. A hyperechoic area of surface part of
hematoma, suggesting a clotted blood of hematoma. The inner part of hematoma indicates
unclotted hematoma. Bar indicates 1 cm.

Ultrasonographic examination on day 3 revealed a large hyperechoic mass measuring 20 x 15 cm, extending directly to the right uterine horn from the body of the uterus (Figs. 2, 3).
Ultrasonography of the hematoma on day 23 reveals loculated hyperechoic spaces
surrounding anechoic areas. As shown in a schema, loculated hyperechoic parts (areas
of clotted and/or organizing hematoma) inside surrounding anechoic parts (areas of
unclotted hematoma) were visible. A size of the whole part of hematoma including
unclotted and clotted hematoma was smaller than that of a handball. Bar indicates 1
cm.

By day 30, the high echo region had gradually changed to several low-echo regions separated by fibrin-like elements (Fig. 4).
