Topic:Case Reports
Case reports in equine medicine provide detailed accounts of individual horses' clinical presentations, diagnostic processes, treatments, and outcomes. These reports are valuable for documenting rare conditions, novel treatment approaches, or unique clinical insights that may not be captured in larger studies. By focusing on individual cases, these reports contribute to the broader understanding of equine health and disease management. They often include comprehensive information on the horse's history, clinical findings, diagnostic tests, therapeutic interventions, and follow-up evaluations. This page assembles peer-reviewed case reports and scholarly articles that explore diverse aspects of equine health, offering insights into specific medical scenarios and their implications for veterinary practice.
Removal of ureteral calculi in two geldings via a standing flank approach. Two geldings, aged 11 and 17 years, were examined for treatment of ureteroliths located approximately 10 cm proximal to the bladder. Results: Ureteral obstruction was an incidental finding in 1 horse that was referred because of urinary tract obstruction and a cystic calculus. This horse did not have clinical or laboratory evidence of renal failure, although severe hydronephrosis was evident on transabdominal ultrasonography. The second patient had a serum creatinine concentration of 6.3 mg/dL (reference range, 0.8 to 2.2 mg/dL) and mild hydronephrosis of the affected left kidney. Results: In ...
Minimally invasive repair of a calcaneus fracture in a Standardbred foal. A 4-month-old Standardbred colt was examined because of a fractured right calcaneus of 8 days' duration with increased distraction of the fracture fragment evident on sequential radiographs. Results: The foal was severely lame with diffuse periarticular tarsal swelling. Radiographically, a complete, displaced long oblique fracture of the right calcaneal body was evident. Because the fracture gap was increasing with time and lameness remained severe, despite medical management, surgical repair was recommended. Results: The foal was anesthetized, and minimally invasive fracture reduction and int...
[Successful treatment of an equine sarcoid. Case report on a combined surgical and photodynamic therapy]. The case report describes the surgical and photodynamic treatment (PDT) of an equine sarcoid in a 6-year-old gelding. A mass on the ventral prepuce, several tumours on the lateral aspect of the prepuce and one sarcoid on the front aspect of the chest were treated. For PDT, Temoporfin (Fospeg® Biolitec AG, Jena) at a concentration of 0.15mg/ml was injected locally. The subsequent irradiation was performed using a red-light laser (652nm) with an energy density of 10J/cm². The mass on the ventral aspect of the prepuce and some of the lateral tumours displayed total remission. The remaining tumo...
Treponemes-infected canker in a Japanese racehorse: efficacy of maggot debridement therapy. A 3-year-old thoroughbred colt presented with canker on its left hind foot. Subsequent development of cottage cheese-like horns and dermatitis disturbed healing, despite the use of miscellaneous orthodox treatment approaches to the lesions. Histological examination revealed exudative and suppurative dermatitis, and proliferatively suppurative epidermitis infected with helically coiled treponemes. Total debridement under general anesthesia led to a temporary improvement, but the ground surface regenerated abnormal epidermis similar to that observed initially after surgery. Maggot debridement th...
Bilateral parotid duct transposition for keratoconjunctivitis sicca in a Connemara stallion. A 7-year-old Connemara stallion was presented with a 4 month history of blepharospasm, recurrent corneal ulcerations, mucopurulent ocular discharge, and keratoconjunctivitis sicca (KCS) in both eyes unresponsive to medical therapy. Ophthalmic examination revealed lackluster corneas, axial corneal scarring and pigmentation with associated neovascularization, and absolute KCS in both eyes. Computed tomography scan and endoscopic evaluation of the upper airway and guttural pouches revealed no structural abnormalities to indicate neurogenic KCS. The stallion was diagnosed with immune-mediated dacr...
Surgical treatment of septic physitis in 17 foals. To document the progression and outcome after surgical curettage of septic physes in foals. Methods: Case series of 17 foals, aged <9 weeks, with septic physitis. Methods: All foals were treated surgically with curettage of physeal lesions. Combinations of systemic antibiotics, intravenous regional perfusion of antibiotic and antibiotic-impregnated polymethylmethacrylate beads were used as adjunct medical treatments.

64, XX, SRY-negative, testicular DSD syndrome in a Lusitano horse. Here is reported a disorder of sex development found in the Portuguese Lusitano horse breed. The complex genital phenotype included mammary glands, abdominal testes without epididymis, connected through oviducts to pelvic hypoplastic uterine horns and fused vulvar labia majora from which protruded ventrally a penis-like structure. This structure was presented in a reversed position, the urethral opening placed dorsally in the glans. However, it was functional both for micturition and erection. The horse exhibited female micturition posture and aggressive male-like behaviour, including flehmen,...
Case series of equine pituitary pars intermedia dysfunction in a tropical climate. The clinical manifestations of equine pituitary pars intermedia dysfunction (PPID) in temperate climates are well described. The classic presentation is that of an older animal with hirsutism, laminitis, poor muscle tone, pendulous abdomen and weight loss. This case series highlights the additional clinical signs of anhidrosis and heat stress with secondary exercise intolerance that were seen as primary presenting problems in equids with PPID in the hot, humid conditions of a tropical climate. The clinical signs resolved with medical treatment for PPID.

Intrathoracic pulsion diverticulum in a horse. This is a report of a 12-year-old Swedish Warmblood gelding with a ruptured esophageal pulsion diverticulum associated with atypical clinical signs of colic and septic peritonitis on presentation. The location of this diverticulum at the hiatus was unique and was most likely responsible for the unusual presentation of this horse. Diverticule de Zenker intrathoracique chez un cheval. Ceci est un rapport d’un hongre de race Swedish Warmblood âgé de 12 ans présentant un diverticule de Zenker perforé associé à des signes cliniques atypiques de coliques et de péritonite septique à la pré...
Ultrasonographic visualization of colonic mesenteric vasculature as an indicator of large colon right dorsal displacement or 180° volvulus (or both) in horses. Visualization of colonic mesenteric vasculature during transabdominal ultrasonographic examination of horses with colic can be a predictor of right dorsal displacement of the large colon or 180° large colon volvulus, or both. Medical records of 82 horses having had surgical treatment of colic and having received a transabdominal ultrasonographic examination on admission were reviewed. Colonic mesenteric vessels were sonographically identified coursing laterally on the right side of the abdomen in 24 of the 82 cases. Horses with colonic vessels identified on ultrasound were 32.5 times more lik...
Early experience with continuous positive airway pressure (CPAP) in 5 horses — a case series. This case series is the first report of the use of CPAP (continuous positive airway pressure) ventilation in adult horses. Two horses and 3 ponies anesthetized for orthopedic procedures in lateral recumbency received 10 cm H(2)O CPAP. During anesthesia, arterial oxygen partial pressure tended to increase and arterial carbon dioxide pressure tended to increase despite increased minute ventilation index. The measured cardiovascular parameters were within physiologic limits. Cette série de cas est le premier rapport sur l’utilisation de la ventilation spontanée en pression positive continue ...

Equine multinodular pulmonary fibrosis in association with asinine herpesvirus type 5 and equine herpesvirus type 5: a case report. A standardbred gelding with a history of 10 days pyrexia and lethargy was referred to the Equine Hospital at the Swedish University of Agricultural Sciences in Uppsala, Sweden.The horse had tachypnea with increased respiratory effort and was in thin body condition. Laboratory findings included leukocytosis, hyperfibrinogenemia and hypoxemia. Thoracic radiographs showed signs of pneumonia with a multifocal nodular pattern, which in combination with lung biopsy findings indicated Equine Multinodular Pulmonary Fibrosis (EMPF). EMPF is a recently described disease in adult horses with clinical s...
Farriery for hoof wall defects: quarter cracks and toe cracks. Conditions that result in the loss of the structural integrity of the hoof wall, such as quarter and toe cracks, are not uncommon and usually manifest in lameness. The successful management of these problems involves identifying and addressing the underlying causes, stabilization of the foot, and committed follow-up.
Septic diseases associated with the hoof complex: abscesses, punctures wounds, and infection of the lateral cartilage. Hoof abscesses are probably the most common cause of acute severe lameness in horses encountered by veterinarians and farriers. Most affected horses show sudden, severe (acute) lameness; the degree of lameness varies from being subtle in the early stages to non-weight bearing. There is still debate between the veterinary and farrier professions as to who should treat a hoof abscess and the best method to resolve the abscess. Puncture wounds to the sole of the foot can introduce bacteria and debris to the solar surface of the distal phalanx and produce a fracture or a septic pedal osteitis.
Nonseptic diseases associated with the hoof complex: keratoma, white line disease, canker, and neoplasia. This article addresses nonseptic diseases associated with the hoof complex, namely keratoma, white line disease, canker, and neoplasia. Keratoma is an uncommon cause of lameness, which may be surgically removed. White line disease, a keratolytic process on the solar surface of the hoof, is treated with therapeutic farriery and resection of the hoof wall when appropriate. Equine canker is an infectious process that results in development of a chronic hypertrophy of the horn-producing tissues. Neoplasia involving the equine foot is rare, and melanoma is the most common type of neoplasm reported....
Treating laminitis: beyond the mechanics of trimming and shoeing. Laminitis is typically classified into developmental or prodromal, acute, subacute, and chronic phases. Scientific evidence regarding the pathophysiology of laminitis does exist, but it is often conflicting and dependent on the clinician's interpretation/understanding of the study or the model used for inducing laminitis. The diagnosis of laminitis consists of obtaining an accurate history, performing a thorough physical examination, and taking good-quality radiographs. The use of radiographs for diagnosis and interpretation of laminitis is an absolute necessity for the clinician. Laminitis is...
Evaluation of cardiac phenotype in horses with type 1 polysaccharide storage myopathy. Type 1 polysaccharide storage myopathy (PSSM1), an equine glycogen storage disorder caused by a gain of function mutation (R309H) in the gene encoding glycogen synthase (GYS1), is associated with the accumulation of amylase-resistant alpha-crystalline polysaccharide inclusions within skeletal muscle. Several glycogenoses in humans have a cardiac phenotype, and reports exist of horses with PSSM and polysaccharide inclusions in cardiac muscle. Objective: To investigate the hypothesis that horses with PSSM1 display a cardiac phenotype. Our objectives were to compare plasma cardiac troponin I (cTn...
Modified Kuhnt-Szymanowski surgical procedure for secondary cicatricial ectropion in a horse. A 1-year-old Dutch Warmblood gelding was presented to the University of Florida's Large Animal Hospital (UF-LAH) for correction of ectropion of the right lower eyelid. The ectropion was the result of a lower eyelid laceration. A primary repair was performed by the referring veterinarian; however, the horse prematurely removed the sutures and the wound healed with inversion of the eyelid margin. Surgical correction of the entropion, with removal of tissue from the lower eyelid, resulted in cicatricial ectropion. During the initial evaluation at UF-LAH, a corneal ulcer was noted in the right eye...
