Angiolipomas are benign mesenchymal tumors infrequently affecting the head and neck region, manifesting themselves as small (<4 cm), slow-growing mass that are painful or tender to palpation. Ultrasonography, fine needle aspiration biopsy, computed tomography, and magnetic resonance imaging can be used to make a diagnosis. Surgical excision is the treatment of choice in both infiltrating and noninfiltrating forms, even if liposuction can be considered in multiple forms. We describe a case of infiltrating intramasseterin angiolipoma, in which diagnosis was suspected after magnetic resonance imaging with gadolinium; then a transoral surgical excision was performed. To the best of our knowledge, only 1 other case of intramasseterin-infiltrating angiolipoma has been previously described.
