Signalment:Adult female massasauga

History:This wild massasauga was from a population in Clinton County, Illinois with a long-term history of ophidiomycosis. In December 2020, this snake was observed above ground and basking instead of brumating underground. It was captured and transported for evaluation on December 29. On presentation, this individual had significant skin lesions consisting of crusting and necrotic scales, especially involving the cloaca. Some thickened caudal coelomic contents were appreciated on palpation.

Gross Lesions:The liver was dark red with sharp margins and contained a focal, pale tan, firm nodule within the parenchyma.
