Posterior ischaemic optic neuropathy is a rare cause of visual loss believed to be due to infarction in the territory of the pial branches of the ophthalmic artery. The disorder most commonly occurs in the context of prolonged surgery or giant cell arteritis, and the absence of clinical signs in the eye means that the diagnosis is one of exclusion. Here, we present two cases studies of patients who developed posterior ischaemic optic neuropathy confirmed by the observation of secondary changes on diffusion-weighted imaging sequences. In the first case visual loss followed robotic pelvic surgery, and in the second case it was associated with multiorgan dysfunction secondary to severe pancreatitis. Our cases demonstrate that in the right clinical context, diffusion-weighted imaging can provide a positive diagnosis of acute posterior ischaemic optic nerve injury in the acute phase.

Visceral artery aneurysms are rare with an incidence of 0.1%-0.2%. Of these, 20% are hepatic artery aneurysms (HAAs). Despite the potential of remaining asymptomatic for long periods of time, the risk of rupture for HAAs is 20%-80%. Treatment includes operative management with open or endovascular techniques. HAA in the setting of pancreatitis has been reported in two prior cases outside of the United States. However, there have been no cases describing the association of HAA and giant cell arteritis (GCA). We present a rare case of an 80-year-old male with a history of GCA who was found to have developed HAA following an episode of acute pancreatitis that was repaired surgically with an open technique. To our knowledge, the association between HAA with acute pancreatitis and GCA has not been reported before.
