Imaging Studies VI: Voiding Cystourethrography and Cystography

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Structural Joints: Synovial Joints

Structural Joints: Synovial Joints

Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Urologic Endoscopic Procedure: Cystoscopic Examination

Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Cholecystitis

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

Summary

Equine articular synovial cysts are rare conditions that can cause lameness in horses. Surgical excision of these cysts offers a successful treatment option, potentially allowing horses to return to work.

Area of Science:

Veterinary Medicine
Equine Surgery
Diagnostic Imaging

Background:

Articular synovial cysts are uncommon in horses.
These cysts can be a source of lameness.
Understanding their clinical presentation is crucial for diagnosis and treatment.

Purpose of the Study:

To detail the clinical findings, diagnostic approaches, treatment strategies, and outcomes for horses with articular synovial cysts.
To evaluate the efficacy of different treatment modalities.

Main Methods:

A retrospective case series involving 16 horses diagnosed with articular synovial cysts between 1988 and 2009.
Data collected included signalment, history, clinical signs, diagnostic imaging (radiography, ultrasonography, arthrography), and treatment outcomes.
Telephone follow-up was conducted to ascertain long-term results.

Main Results:

Lameness was the primary presenting complaint in most horses (n=9).
Diagnosis relied on palpation and various imaging techniques.
Surgical excision was performed in 8 horses, with lameness resolution in 3. Two conservatively treated horses performed satisfactorily.

Conclusions:

Equine articular synovial cysts are rare but can cause significant lameness.
Surgical excision is a potentially successful treatment, enabling horses to return to athletic function.
The cysts consistently demonstrated a synovial lining upon assessment.
