Computed tomography of infiltrating benign lipoma

Lipomas are frequently encountered benign tumors of adipose tissue origin. A lipoma generally develops in the superficial subcutaneous tissues but may occasionally be deep seated, growing between or within muscles. Deep-seated lipomas (excluding body cavities and viscera) have been termed infiltrating benign lipomas, of which there are two varieties--lipoma and angiolipoma. We wish to report three cases of infiltrating benign lipomas. Computed tomography scanning is the diagnostic modality of choice in the evaluation of these tumors.
