In this study, the short tau inversion recovery changes identified were restricted to cases with inflammatory spinal cord disease. The short tau inversion recovery change had a sensitivity of 78%, and a specificity of 92% in predicting inflammatory cerebrospinal fluid, suggesting that short tau inversion recovery sequences are a useful addition to the investigation of suspected inflammatory spinal cord disease.

“…MRI is superior to CT in displaying soft tissue changes. To the authors knowledge it has been used in single cases of an iliopsoas myositis [26] cases of iliopsoas abscess [27,28], a fibrotic myopathy [29], a primary hemangiosarcoma of the iliopsoas muscle [30], and a femoral neuropathy in a dog with iliopsoas muscle injury [8].…”

“…Another author describes them as calcifying tendinopathies occurring unilateral or bilateral and rarely causing associated clinical signs [6]. The most striking clinical symptom in insertion tendinopathy of the iliopsoas muscle is intermittent lameness of the hind limb, which is described as unilateral, bilateral, acute and chronic [2][3][4][7][8][9]. To the authors knowledge no further investigations about different shapes or possible changes of the lesser trochanter exist nor at which age changes may occur.…”

The purpose of this retrospective study is to describe the radiographic morphology of the lesser trochanter as well as possible enthesiopathies of the iliopsoas muscle in Rottweilers, German Shepherd Dogs and Bavarian Mountain Hounds. The normal shape of the lesser trochanter appeared radiological triangular in German Shepherd Dogs and blunt or bump like in Rottweilers and Bavarian Mountain Hounds. Changes indicating an enthesiopathy presented as periosteal blurrings, variation in shape or in isolated bone opacity proximomedial to the lesser trochanter and were categorized into four groups. Three aspects were of special interest: general frequency of radiographic signs of enthesiopathy and potential correlation to sex or to hip dysplasia. In total 736 radiographic studies from Rottweilers (n=311), German Shepherd Dogs (n=133) and Bavarian Mountain Hounds (n=292) have been evaluated. Changes of the lesser trochanter are present in 105 (14.2%) of the radiographic studies. In Rottweilers and Bavarian Mountain Hounds enthesiopathy is significantly correlated to hip dysplasia as dogs classified as "C", "D" and "E" were merged as one group. Regarding gender disposition no correlation was found. Computed tomography (CT) was additionally available in nine dogs and confirmed radiographic findings. The results of this study could be of major interest in the selection process of service, working and sports dogs as enthesiopathies of the iliopsoas muscle occurring in adolescent dogs might act as a life-long weak points, but additional data is needed to evaluate clinical relevance AbstractThe purpose of this retrospective study is to describe the radiographic morphology of the lesser trochanter as well as possible enthesiopathies of the iliopsoas muscle in Rottweilers, German Shepherd Dogs and Bavarian Mountain Hounds.

Objective:Iliopsoas injury and strain is a commonly diagnosed disease process, especially amongst working and sporting canines. There has been very little published literature regarding iliopsoas injuries and there is no information regarding the ultrasound evaluation of abnormal iliopsoas muscles. This manuscript is intended to describe the ultrasound findings in 73 canine agility athletes who had physical examination findings consistent with iliopsoas discomfort. The population was chosen given the high incidence of these animals for the development of iliopsoas injury; likely due to repetitive stress. Methods:Medical records of 73 agility performance canines that underwent musculoskeletal ultrasound evaluation of bilateral iliopsoas muscle groups were retrospectively reviewed. Data included signalment, previous radiographic findings, and ultrasound findings. A 3-tier grading scheme for acute strains was used while the practitioner also evaluated for evidence of chronic injury and bursitis. Results:The majority of pathologies were localised to the tendon of insertion, with the majority being low grade I-II strains (80.8%). Tendon fibre disruption (71.2%) and indistinct hypoechoic lesions (91.8%) were the most common of acute changes noted. Hyperechoic chronic changes were noted in 84.9 percent of cases. Acute and chronic changes were commonly seen together (62.8%). Conclusion:Diagnostic musculoskeletal ultrasound was used to identify lesions of the iliopsoas tendon consistent with acute and chronic injury, as well as identifying the region of pathology. The majority of agility performance dogs had low grade acute strains based on the tiered system, with mixed acute and chronic lesions being noted frequently. Application:Diagnostic musculoskeletal ultrasound provides a non-invasive diagnostic modality for patients suspected of having an iliopsoas strain.

Femoral Neuropathy in a Dog with Iliopsoas Muscle Injury

Abstract: Iliopsoas muscle injury should be considered in patients with hip pain and MRI is a useful test for diagnosis. Tenectomy may be indicated for relief of chronic iliopsoas muscle pain.
