Osteochondroma of the First Phalanx in Tbourida Horses

Abstract: This study aimed at describing anatomo-histopathological and imaging features, using computed tomography and magnetic resonance imaging on six ex vivo forelimbs of Tbourida horses, that presented a particular bone exostosis on the dorsal and proximal part of the first phalanx, diagnosed by X-ray. Gross anatomy of the bone exostosis revealed an irregular surface with poly-lobulated tissue masses showing a cauliflower shape. The diameter/depth varied from 0.5 to 5.1 cm with a mean of 3.9 ± 0.9 cm. The capsule of… Show more

“…Histological examination of the OBE revealed a cap of hyaline cartilage, including large foci of endochondral ossification with a base of cancellous bone surrounding marrow spaces, which confirmed the diagnosis of osteochondroma lesion. Such osteochandroma lesions are rare in horses [32].…”

“…A particular radiographic finding showing a bony overgrowth that looked like an exostosis on the dorsal and proximal part of the P1 was observed in 19,6% of the examined horses. In a recent study, we have diagnosed this lesion as an osteochondroma of the P1 [32]. Indeed, using different approaches (Computed tomography, Magnetic resonance imaging, histology analysis) on six ex vivo forelimbs of Tbourida horses that presented a particular OBE on the dorsal and proximal part of the P1 diagnosed previously by X-ray, computed tomography (CT) showed bone remodeling on the dorsal and proximal surface of the P1, with the presence of several bone fragments at this level.…”

“…These findings increase the index of suspicion of an osteochondroma; however, histopathology is necessary for a definitive diagnosis. There have been reports of advanced imaging techniques such as scintigraphy, CT and MRI, being used to aid diagnosis of osteochondroma (Secombe and Anderson 2000;Dixon and Anderson 2019;Seghrouchni et al 2019). Non-contrast CT and MRI were used to aid the diagnosis of an osteochondroma on the proximal phalanx (Seghrouchni et al 2019).…”

Non-contrast CT and MRI were used to aid the diagnosis of an osteochondroma on the proximal phalanx (Seghrouchni et al 2019). Sechrouchni et al (2019) described how CT provided essential cross-sectional information about the cortical and medullary continuity of the osteochondroma with the underlying bone.…”
