In this case study, an 8‐year‐old Warmblood‐cross mare presented for investigation of acute onset left hindlimb lameness.

In September 2020, a case report was published titled, "Advanced imaging of a histologically confirmed bone infarction of the distal tibia in a Warmblood mare" in BEVA's and AAEP's Equine Veterinary Education journal. The study was authored by lead author M.J. Hann of the Department of Equine Clinical Science, Institute of Veterinary Science, University of Liverpool, U.K. His fellow university authors were G. Rocchigiani, R Verin, P. Milner, and M. Castro Martins, plus C. Robinson from the Nantwich Veterinary Group Equine Centre.

Summary

"An 8‐year‐old Warmblood‐cross mare presented for investigation of acute onset left hindlimb lameness. Nuclear scintigraphy identified a marked, focal, increase in radiopharmaceutical uptake in the distal aspect of the left tibia. Radiography revealed a large, oval, multi‐loculated radiolucent area within the medulla of the distal metaphysis of the left tibia. The mare was treated conservatively for 6 months but showed little improvement in the lameness so the owner elected for euthanasia. Post‐mortem computed tomographic imaging revealed a large, oval, hypoattenuating area within the distal tibia, surrounded by a thick, irregular, sclerotic border. The lesion occupied the majority of the medullary cavity but the cortical bone was unaffected. Gross and histopathological examination confirmed a diagnosis of a bone infarction in the medullary cavity of the distal tibia."
