Multimodal Imaging to Identify and Characterize a P3 Cystic Lesion and Pathologic Fracture

Complete fractures through osseous cyst‐like lesions of the proximal phalanx in three horses

“…The OCLLs of the proximal phalanx in this case series show very different characteristics to the cases with fractured cystic lesions mentioned in the introduction (Ball et al, 2020;Fuggazola et al, 2014;Moser et al, 2017). OCLLs of the P1 are much smaller than those reported in humans.…”

“…Only three cases of fractures associated with preexisting cysts in horses have been presented to date (Ball et al., 2020; Fuggazola et al., 2014; Moser et al., 2017). In two cases, a fracture through an existing large osseous bone cyst in the distal phalanx (P3) and a collapse of a large medial femoral condyle (MFC) SCL, humane euthanasia was elected (Ball et al., 2020; Moser et al., 2017).…”

The one case which resulted in a favourable outcome was reported to be an 18‐month‐old filly with a large unicameral bone cyst in the greater tubercle of the right front humerus (Fuggazola et al., 2014).…”
