M71.31
Other bursal cyst, shoulder
Clinical Classification Guidelines
Medical Intelligence & Overview
An other bursal cyst in the shoulder, classified under ICD-10 code M71.31, refers to a fluid-filled sac that develops in the subacromial or subdeltoid bursa of the shoulder. Bursae are small fluid-filled sacs that help reduce friction between tissues, especially around joints. When these sacs become cystic or develop a cyst, they can cause discomfort and limit movement. This condition is typically associated with inflammation or degeneration of the bursa but can also arise due to trauma or repetitive use.
Causes & Symptoms
Clinical Causes: Repetitive shoulder movements or overuse Chronic inflammation or bursitis Shoulder injury or trauma Degenerative changes in shoulder tissues Infections leading to cyst formation Underlying shoulder joint conditions like osteoarthritis or rotator cuff pathology
Key Symptoms: Pain or tenderness in the shoulder, especially when moving or lying on the affected side Swelling or a palpable lump over the shoulder Restricted range of motion due to discomfort or mechanical obstruction Weakness in shoulder movements Discomfort that worsens with activity or at night Possible warmth or redness if associated with inflammation or infection
Diagnostic & Treatment
Diagnosis Path: Physical examination to check for swelling, tenderness, and range of motion limitations Imaging tests such as ultrasound to visualize fluid-filled sacs and assess their size Magnetic resonance imaging (MRI) for detailed images of shoulder tissues, helping distinguish bursal cysts from other soft tissue masses Aspiration of fluid, if necessary, to analyze for infection or other pathological changes
Treatment Protocols: Rest and avoiding activities that exacerbate symptoms Application of ice packs to reduce swelling and pain Nonsteroidal anti-inflammatory drugs (NSAIDs) to manage pain and inflammation Physical therapy programs to strengthen shoulder muscles and improve mobility Corticosteroid injections to decrease inflammation within the bursa Drainage of the cyst if it is large, painful, or resistant to conservative procedures Surgical removal may be considered if symptoms persist despite non-invasive treatments or if the cyst impairs shoulder function
