This report describes two cases of successful surgical management of granulosa cell tumours (GCT) in mares presenting with haemoperitoneum (HP). Controlled abdominal drainage was initially attempted in Case 1 but was not successful. A ventral midline exploratory laparotomy allowed removal of a haemorrhaging 13 kg GCT. The mare made a full recovery and returned to normal work as a driving pony 11 months post-operatively. In Case 2 controlled abdominal drainage was followed by standing left flank laparoscopic visualisation of the bleeding ovary and transection of the ovarian pedicle by electrocautery. The GCT was then removed via a ventral midline incision due to its large size. Haemoperitoneum can be associated with GCTs and in some cases is severe enough to prompt emergency treatment. Stabilisation of the patient and removal of the haemorrhaging GCT can lead to a successful outcome.
