Purpose of exam: Evaluation of reproductive function and pathology.

Reproductive History:

Panjang appeared to be a reproductively active female earlier this year based upon animal behavior, endocrine data and ultrasound evaluation. Unfortunately, Dr. Terri Roth reported a large 12 cm diameter uterine mass visible on ultrasound within the caudal aspect of the uterus during her examination in March of 2001. This mass was thought to be associated with a bloody vaginal discharge discovered 18 days following breeding in October of 2000. Based on the large size and subsequent passage of the mass (Figure 1) the original location was likely within the cranial vagina and not the uterus as previously suspected. A vaginal location would also support the clinical picture of vaginal hemorrhage post-breeding. more »
