What is the best course of action for a patient with a history of Carney Complex and previous ganglion cysts, presenting with intermittent deep ache in the right axillary area, exacerbated by weightlifting or yoga?

Axillary Pain with Exercise in Patient with Carney Complex and Prior Ganglion Cysts

Begin with plain radiographs of the right shoulder and axilla to exclude osseous pathology, followed by ultrasound of the axillary region to evaluate for soft tissue masses including ganglion cysts, given this patient's history and the intermittent, activity-related nature of symptoms. 1

Initial Diagnostic Approach

Clinical Assessment Priorities

• Document the exact location, timing, and reproducibility of pain with specific movements (overhead lifting, yoga positions requiring shoulder external rotation or abduction) 1
• Palpate the axillary region systematically for masses, tenderness, or neurovascular abnormalities, as axillary masses have a broad differential including ganglion cysts, vascular lesions, and soft tissue tumors 1
• Assess for neurologic symptoms including numbness, tingling, or weakness that might suggest nerve compression from a mass lesion 1

First-Line Imaging Strategy

• Obtain shoulder radiographs (AP, lateral, and axillary views) as the initial imaging modality to evaluate for bone abnormalities, calcifications, or joint pathology that could explain axillary pain 1
• Perform ultrasound of the axillary region if radiographs are normal or nonspecific, as US is highly effective for evaluating soft tissue masses including ganglion cysts and has comparable accuracy to MRI for extra-articular soft tissue pathology 1

Advanced Imaging When Indicated

MRI Considerations

• If ultrasound is inconclusive or demonstrates a complex mass requiring further characterization, obtain MRI of the shoulder and axilla without contrast 1
• MRI provides superior soft tissue detail and can identify occult ganglion cysts, vascular abnormalities, or nerve-related pathology that may not be fully characterized on ultrasound 1, 2
• Consider MRI with contrast if there is concern for atypical features such as solid components, irregular borders, or findings suggestive of neoplasm rather than simple cyst 1

Special Considerations for This Patient

Carney Complex Implications

• Carney Complex predisposes to multiple benign and malignant tumors, so any axillary mass requires careful evaluation to exclude myxomas, schwannomas, or other complex-associated neoplasms 1
• Maintain heightened suspicion for atypical presentations given the syndromic nature of this patient's condition 1

Ganglion Cyst Recurrence Pattern

• Prior ganglion cysts increase likelihood of recurrent cyst formation, particularly in areas subject to repetitive motion or mechanical stress 3, 4
• Ganglion cysts can arise from joints and dissect along paths of least resistance, potentially tracking into the axilla from shoulder joint connections 2
• Activity-related symptoms are characteristic of ganglion cysts, as mechanical stress and joint motion can cause intermittent compression or tension on surrounding structures 3, 5

Management Algorithm

Conservative Management First

• If imaging confirms a simple ganglion cyst without neurovascular compromise, initiate activity modification by avoiding provocative movements (heavy weightlifting, extreme yoga positions) for 4-6 weeks 3, 4
• Consider aspiration for symptomatic relief if the cyst is accessible and causing significant functional limitation, though recurrence rates are higher than with surgical excision 4

Surgical Intervention Criteria

• Recommend open surgical excision if conservative measures fail after 6-8 weeks or if the cyst causes persistent pain, weakness, or limitation of activities of daily living 3, 4
• Complete excision of the ganglion complex including the stalk and capsular attachment is essential to minimize recurrence risk, which ranges from 4-12% with proper technique 3, 5, 4
• Intentional cyst rupture during surgery may facilitate identification of the stalk when severe adhesions obscure anatomy, improving completeness of resection 3

Critical Pitfalls to Avoid

• Do not assume this is a simple musculoskeletal strain without imaging, as the patient's Carney Complex and prior ganglion history warrant thorough evaluation for structural pathology 1
• Do not proceed directly to MRI without obtaining radiographs first, as this violates standard imaging algorithms and may miss important osseous findings 1
• Do not dismiss intermittent symptoms as insignificant, as ganglion cysts characteristically produce activity-related pain that may be absent at rest 3, 4
• Do not perform incomplete excision if surgery is undertaken, as failure to identify and remove the stalk and capsular attachment is the primary cause of recurrence 3, 4
• Do not overlook the possibility of complex-associated neoplasms that may mimic benign cysts on initial evaluation, particularly in patients with tumor predisposition syndromes 1
