“…In horses it has been described within a femorotibial bursae (Kirk, 1982), metatarsophalangeal joints (Smith et al, 1995) and a middle carpal joint (Newman et al, 2014). Intra‐synovial soft tissue tumours reported in horses include mastocytomas (Leadbeater et al, 2010; Uehlinger et al, 2010), lipomas (Hammer et al, 2002; Owens et al, 2017) and a fibroma (Rich et al, 2021). Intra‐articular mass‐like lesions caused by non‐septic chronic inflammation can be classified as villonodular synovitis (Nickels et al, 1976) or chronic proliferative synovitis (Veenedaal & Moffatt, 1980).…”

Summary This case report describes the diagnosis and arthroscopic removal of a ruptured epidermoid cyst in a distal interphalangeal (DIP) joint of a horse. The cyst was the cause of chronic moderate lameness and following removal the horse returned to athletic performance. However, 12 months postoperatively the horse was retired due to the recurrence of lameness. Epidermoid cysts have been diagnosed elsewhere in the equine digit but have not been reported intra‐articularly to the best of our knowledge.

BackgroundNon‐septic tenosynovitis is a clinically relevant and often performance limiting musculoskeletal injury in the horse.ObjectivesTo review the published literature to determine which tendon sheaths are commonly affected by non‐septic tenosynovitis and to describe the most frequently reported pathological lesions, outcomes, and surgical complications in equine non‐septic tenosynovitis.Study designSystematic review.MethodsLiterature searches were conducted in July 2021 from the online search engines PubMed, Scopus, Web of Science Core, VetMed Resource and ProQuest Theses & Dissertations. The inclusion criteria followed a participants, interventions, comparisons, outcome and study design (PICOS) approach. For inclusion, studies had to include live equids with non‐septic tenosynovitis of any tendon sheath. Studies were excluded if they only described non‐equine species, if they included data only on non‐tendon sheath structures, or if they included data exclusively on cases of septic or contaminated tendon sheaths. Determination of non‐sepsis relied on the diagnosis of the original authors; however, if non‐sepsis was not explicitly specified, then cases that had a history of contamination of the sheath, a wound near the sheath or a positive bacterial culture were excluded from analysis. Data analysed included the distribution of structures affected by non‐septic tenosynovitis, the most common pathological lesions identified within each sheath, and the most frequently reported surgical complications of non‐septic tenosynovitis. The quality of each study was assessed using a methodological quality analysis.ResultsA total of 85 studies describing non‐septic tenosynovitis in the horse were included. Across all 85 studies, there were a total of 2449 tendon sheaths in 2101 horses reported to be affected by non‐septic tenosynovitis. The digital flexor sheath was the most reported structure to be diagnosed with non‐septic tenosynovitis: 41/85 (48%) studies examined the digital flexor sheath exclusively, followed by the carpal flexor sheath, tarsal flexor sheath, carpal extensor sheaths, tarsal extensor sheaths, and one case of biceps brachii non‐septic tenosynovitis. For most tendon sheaths, the most common pathological lesion was an intrathecal tear of a soft tissue structure, including tears of the deep digital flexor tendon and tears of the manica flexoria. Bilateral disease was most common in the carpal flexor sheath, where distal radial physeal exostoses were the most common pathological lesions. Less common causes of non‐septic tenosynovitis included neoplasia, fracture of a bone adjacent to a tendon sheath, and mineralisation of an intrathecal tendon. The likelihood of return to previous level of athletic function following non‐septic tenosynovitis of most structures was approximately 50%, and the most common complication was persistent effusion following tenoscopy. While iatrogenic infection following surgery was uncommon, it was most likely following tenoscopy of the digital flexor sheath.ConclusionNon‐septic tenosynovitis is commonly reported in equine athletes, with intra‐thecal tears of the deep digital flexor tendon, superficial digital flexor tendon and manica flexoria frequently reported. Directions for future research include more thorough assessment of and reporting of complications following non‐septic tenosynovitis and correlation of characteristics of intrathecal pathological lesions with clinical outcomes.

Summary Small intestine strangulation by pedunculated lipomas is a common cause of acute colic in horses. However, diagnosis of this condition prior to surgery may be difficult due to the poor specificity of the clinical signs. We describe the ultrasonographic findings of 2 horses presented for acute colic with a diagnosis of strangulating lipoma confirmed in surgery. Lipomas were identified as rounded and well‐defined, homogeneous hyperechoic structures, surrounded by distended small intestine loops and peritoneal fluid. Ultrasonographic identification of lipomas should be attempted during an abdominal scan, especially in horses with evidence of small intestinal ileus and/or obstruction.
