Cardiothoracic Surgery: Elastofibroma Dorsi

Basics

• Benign Soft Tissue Pseudotumor
• Most Common Site: Subscapular/Infrascapular at the Lower Pole of the Scapula, Deep to the Serratus Anterior
• Slow Growing
• May Be Bilateral (13-33%)
• Most Common in Women
• Most Common in Elderly (Age > 50-60 Years)

Presentation

• Often Asymptomatic
• Pain/Discomfort
• Swelling
• “Snapping” of the Scapula with Movement

Diagnosis

• MRI: Streaks of Fibrous & Fatty Tissue
• Often Difficult to Exclude Soft Tissue Sarcoma on Imaging – May Require Core Needle Biopsy

Treatment

• Asymptomatic: Nothing
• Symptomatic: Surgical Excision
  • High Rates of Hematoma/Seroma (40-80%) – Should Have About One Week of Suction Drainage with Limb Immobilization
