An enostosis‐like lesion was diagnosed in the left femur of a Swedish Warmblood horse that had a left hindlimb lameness of 3 weeks duration. With scintigraphy using technetium 99m‐hydroxymethylene diphosphonate ( 99m Tc‐HDP) a marked regional focal increase in radioactivity was identified in the medullary cavity of the left femur. Radiographically there was a corresponding focal increase in bone opacity in the middiaphysis of the left femur. Histopathologically, a 5 cm area of bone matrix was present in the diaphysis of the left femur and confirmed as an enostosis‐like lesion. Enostosis‐like lesions should be considered as a source of pain in horses with difficult to localize, moderate to severe chronic lameness.
