66 pigs from 52 premises have been found to be affected by a cerebrospinal angiopathy. In 64, symptoms first appeared in the 5 weeks following weaning. The lesions were characterised by thickening of the walls of the small arterioles of the central nervous system, swelling and degeneration of their medial cells, subendothelial hyaline deposits, and perivascular eosinophilic droplets. In a proportion of cases, similar vascular lesions were found in the tongue, pancreas, liver, small intestine and adnexa of the eye.
