Plain-English summary
This study looked at how ultrasound can help diagnose granulosa cell tumors in mares, which are a type of ovarian tumor. The researchers examined seven cases and found that these tumors could look different, sometimes appearing dense or having large fluid-filled areas. Some of the tumors looked similar to other ovarian issues, making it hard to identify them just by their ultrasound images. While there isn't a clear ultrasound picture that can confirm a granulosa cell tumor on its own, using ultrasound along with the horse's medical history and a physical exam can be helpful for veterinarians.
Abstract
The ultrasonic appearance of seven cases of granulosa cell tumour is described, and compared with an ovarian haematoma and an ovarian serous cystadenoma. The granulosa cell tumours varied from being uniformly dense to having one or several large fluid filled cysts. Some tumours resembled the haematoma or cystadenoma and also, in some aspects, normal ovarian structures such as corpora haemorrhagica or follicles in early pregnancy. There was no typical ultrasonographic appearance of the granulosa cell tumours which enabled definitive diagnosis. However, ultrasound may be a diagnostic aid when used in conjunction with the history and findings on rectal palpation.
