Spindle cell lipoma of the mediastinum: a differential consideration for liposarcoma.

Spindle cell lipoma is a benign lesion most commonly found on the posterior neck and shoulders. It shares many imaging characteristics with liposarcoma, including the presence of adipose and soft tissue elements. Although its benign nature precludes the necessity of surgical resection for treatment, surgery is often required for tissue diagnosis. We report a case of spindle cell lipoma arising in the anterior mediastinum.
