Unilateral leg edema: Is it always vascular?

Area of Science:

• Vascular Medicine
• Dermatology
• Endocrinology

Background:

• Unilateral lower extremity edema is commonly attributed to deep venous thrombosis, venous insufficiency, or lymphedema.
• Diagnostic workup typically involves patient history, physical examination, and venous duplex ultrasound.
• Vascular etiologies are frequently identified as the cause of leg swelling.

Observation:

• A case report details a 23-year-old patient presenting with unilateral leg swelling.
• The patient underwent a diagnostic evaluation to determine the cause of edema.
• Initial assessments might not immediately suggest the underlying condition.

Findings:

• The diagnostic workup revealed lipedema as the cause of the patient's unilateral leg edema.
• Lipedema is characterized by the deposition of subcutaneous adipose tissue.
• While uncommon in general cardiology clinics, lipedema is a recognized cause of edema in specialized settings.

Implications:

• Highlights the importance of considering less common causes of edema, such as lipedema.
• Suggests that specialized clinics may encounter lipedema more frequently than general practices.
• Emphasizes the need for comprehensive diagnostic approaches for persistent unilateral leg swelling.
