[more ▼] This chapter is part of a comprehensive book on veterinary diagnostic radiology and illustrates abnormal radiological features of stifle and tarsus disease in the horse. The best radiographic technique for each disease is briefly described and ultrasonography is mentionned as a complementary examination when needed. More than 3O illustrations are available in the chapter. Chapter quizzes, key points and case studies are available on internet at http://evolve.elsevier.com/Thrall/vetrad.

[more ▼] This retrospective study reports diagnostic findings in 74 horses with ultrasonographic diagnosis of femorotibial joint damage; it describes the ultrasonographic features of meniscal tears and determines the prevalence of medial or lateral meniscal involvement and of associated synovial effusions. Horses were classified into four groups: with medial meniscal damage, with lateral meniscal damage, with lesions in both menisci, and with no ultrasonographic evidence of meniscal damage. After ultrasonographic appearance, meniscal lesions were described as central degeneration, horizontal tear, partial oblique tear of the distal angle, combined horizontal and oblique tears, or complex tear. Meniscal protrusion or other associated ultrasonographic or radiographic abnormalities were recorded. Of the 74 horses, 54 (73%) had medial meniscal damage, 5 (6.75%) had lateral meniscal damage, 5 (6.75%) had lesions in both menisci, and 10 (13.5%) had no meniscal lesion. Meniscal protrusion occurred in 20 cases (27%). Horizontal tears were the most frequent type of meniscal lesion (26 horses). Complex lesions were found in 6 lateral menisci and 14 medial menisci. Lesions of the cranial meniscal ligaments were seen in 10 horses. Synovial effusion of one or several joint compartments was found in 51 cases (68.9%). This study demonstrates the high prevalence of meniscal tears and synovitis in horses with ultrasonographic evidence of femorotibial derangement. Based on this series of clinical cases, horizontal tears of the medial meniscus appear to be the most frequent soft tissue injury of the equine stifle.

[more ▼] The objective was to describe the ultrasonographic features of the lesions of the podotrochlear apparatus identified when the foot is imaged through the frog in equine cadaver digits and to compare the ultrasonographic graphic changes with macroscopic findings. Fourteen cadaver feet with abnormalities of the podotrochlear apparatus detected by transcuneal ultrasonography were used for the study. The palmarodistal portion of the podotrochlear apparatus was studied and imaged using the transcuneal approach. The detectable ultrasonographic findings suggesting pathology of the podotrochlear apparatus were described. Ultrasonographic and gross findings in the podotrochlear apparatus were compared to interpret the transcuneal ultrasonographic changes.

[more ▼] The urinary bladder of four dogs with emphysematous cystitis was assessed radiographically. Ultrasonography was also performed using a 7.5-MHz microconvex probe in dorsal recumbency and in a standing position. Ultrasonographically there were bright echoes and reverberations typical of gas in all dogs. This was entrapped in the bladder wall as it appeared in the same location in recumbent and standing positions. Bladder size was reduced and bladder content was echogenic in all dogs. In only one out of the four dogs was a gas stripe seen in the bladder on radiographs. Proteus mirahilis was isolated from the urine of all patients. Diabetes was ruled out on the basis of urine and blood analysis. A small amount of gas can be difficult to detect on radiographs. Ultrasonography appears to be a more sensitive technique for detection of gas within the bladder at an early stage of emphysematous cystitis. Prevalence of emphysematous cystitis may be underestimated if only radiographs are made.

[more ▼] We describe the abnormal magnetic resonance (MR) imaging findings in the deep digital flexor tendon (DDFT) and distal sesamoid bone in horses with radiographic changes compatible with navicular syndrome. Thirteen postmortem specimens were examined using a 1.5-T magnetic field, with spin echo (SE) T1-weighted, turbo SE (TSE) proton density-weighted (with and without fat saturation), and fat saturation TSE T2-weighted sequences. The limbs were then dissected to compare the MR findings with the gross assessment and histologic examination of the DDFT and distal sesamoid bones. Tendonous abnormalities were detected by MR imaging in 12 DDFTs and confirmed at necropsy. Most tendon lesions were located at the level of the distal sesamoid bone and the proximal recess of the podotrochlear bursa. Tendon lesions were classified based on their MR imaging features as core lesions, dorsal lesions, dorsal abrasions, and parasagittal splits. Areas of increased MR signal in the DDFTs were characterized by tendon fiber disturbance and lack of continuity of the collagen fibers, foci of edema, hemorrhages, and formation of lakes containing eosinophilic plasma-like material or amphophilic material of low density. Bone marrow signal alterations in the distal sesamoid bone were seen in all digits. Two main phenomena were responsible for the abnormal signal, respectively, in T1-weighted (decreased signal) and in T2-weighted fat-suppressed images (increased signal): a decrease in the fat marrow content in the trabecular spaces and an increase in the fluid content. Histologic examination revealed foci of bone marrow edema, hemorrhage, necrosis, and fibrosis. Cyst formation and trabecular abnormalities (disorganization, thinning, remodelling) were also observed in areas of abnormal signal intensity. Increased bone density because of trabecular thickening induced a decrease in signal in all sequences. [less ▲] Detailed reference viewed: 50 (10 ULg) |
