A juvenile Deckert's rat snake, Elaphe obsoleta deckerti, was presented with a circumferential enlargement of the body in the region of the heart. The heart was enlarged approximately twice normal size. Focal mineralized lesions were present in the tunica media of the right aorta and the right atrioventricular valve. The normal sinusoid architecture of the liver was disrupted with deeply eosinophilic to lightly basophilic granules of variable size in the cytoplasm and light eosinophilic intranuclear inclusions. Similar appearing intracytoplasmic granules were seen in the glomeruli and kidney tubules.
