A 23-year-old female imprinted steppe eagle (Aquila nipalensis) was presented by a public falconry centre for postmortem examination following sudden death with no previous clinical signs. Postmortem examination revealed the presence of 150 ml of blood within the coelomic cavity, with a packed cell volume of 42% indicating an acute, internal haemorrhage as a presumptive cause of death. A well-demarcated, solid, hard, ovoid, approximately 3 cm×2 cm (in cross section) mass was discovered within the body of the aorta adjacent to the ovary. Histological examination confirmed this to be an aortic aneurysm underlain by severe atherosclerosis with a transmural rupture.

Paraphimosis and penile prolapse have been described in hystricomorph rodents. Commonly the cause is a ring of fur or debris, found at the base of the penis, especially in chinchillas. Other causes described include infection, trauma and irritation. In dogs, preputial reconstruction is used to narrow the preputial orifice. In this case, a degu was seen for recurrent penile prolapse. An excessively wide preputial orifice was the presumptive aetiology. A simple surgical technique for prevention of persistent penile prolapse is described. The technique involves narrowing the preputial orifice without risking iatrogenic damage to the penis or urethra with a simple suture to approximate both sides of the mucosa on the ventral aspect of the distal preputial orifice. No recurrence or micturition problems were seen 18 months following surgery.
