Ultrasonographic and computed tomographic features of rice bodies in an Arabian horse with atlantal bursitis.
Abstract: A 19-year-old castrated Arabian male horse presented for evaluation of a firm mass at the dorsal cervical region. Ultrasonography and computed tomography revealed multiple well defined fusiform structures within the atlantal bursa. Multiple glossy smooth, white to yellowish, flattened fusiform structures were removed surgically. These structures were composed of dense fibrin with some leukocytes and red blood cells. The imaging and histopathological features of these structures were similar to chronic 'rice bodies' reported in humans with bursitis or tenosynovitis. This is the first veterinary report describing the imaging features of 'rice bodies' in a horse with atlantal bursitis.

This research presents a case study on an Arabian horse with atlantal bursitis, where ultrasonography and computed tomography were used to identify and examine ‘rice bodies’ – dense fibrinous structures typical of chronic inflammation.
Objective of Study
- The paper investigates a case of atlantal bursitis in a 19-year old, castrated, Arabian male horse. The particularly novel aspect is the recognition and description of ‘rice bodies,’ via ultrasound and computed tomography, within the atlantal bursa of the horse, never reported before in veterinary literature.
Case presentation
- A firm mass was detected in the dorsal cervical region of the horse, leading to a consultation for evaluation. Medical imaging techniques, including ultrasonography and computed tomography, were used to view the calcified structures present within the bursa.
‘Rice body’ imaging
- Both imaging techniques revealed the presence of well-defined fusiform structures within the horse’s atlantal bursa. These structures, reminiscent of what human medicine refers to as ‘rice bodies,’ are often identified in patients with bursitis or tenosynovitis. It’s the first time they were identified in a horse.
Surgical Procedure and Results
- The identified structures were surgically removed. These structures appeared as glossy, smooth and were white to yellowish in color, having a shape similar to that of rice grains.
- The structures comprised of dense fibrin, which is a protein involved in blood clotting, specifically, with some leukocytes, which are white blood cells, and red blood cells.
Conclusion
- The analysis post-surgery confirmed the ‘rice bodies’. The extracted structures shared similar imaging and histopathological features with those reported in human bursitis or tenosynovitis cases.
- The recognition of these structures in a horse is the first of its kind. This work expands veterinary literature and our understanding of inflammation in horses.
