Large lipoma of chest wall

Ultrasound Imaging Findings of Large Lipoma of the Chest

Ultrasound Imaging Findings:

1. Hyperechoic Mass: Lipomas typically appear as well-defined, hyperechoic (bright) masses on ultrasound due to their high fat content.

2. Homogeneous Texture: Lipomas have a uniform texture, with a smooth and consistent echogenicity throughout the lesion.

3. Posterior Acoustic Enhancement: Lipomas often exhibit posterior acoustic enhancement, causing increased brightness behind the mass due to sound waves passing through the fatty tissue.

4. Well-Circumscribed Borders: These benign tumors have clear, distinct borders that differentiate them from surrounding tissues.

5. Lack of Vascularity: Lipomas usually lack significant blood flow, as they are non-vascular structures.

Differential Diagnoses:

1. Liposarcoma: It can mimic a lipoma but tends to be larger, more heterogeneous, and may show vascularity on imaging.

2. Sebaceous Cyst: These cysts may appear similar but tend to have a central punctum and may be associated with skin changes.

3. Hemangioma: Vascular tumors may show significant blood flow and a different echogenicity pattern.

Prognosis:

Lipomas are typically benign and do not pose a significant health risk. They rarely become malignant, and the prognosis is excellent.

Management:

1. Observation: Asymptomatic lipomas may be left alone and monitored.

2. Surgical Removal: Indicated for large, symptomatic, or cosmetically bothersome lipomas. Excision is curative.

3. Biopsy: If there is uncertainty about the diagnosis, a biopsy may be performed.

Always consult a healthcare professional for proper evaluation and management.
