A 58-year-old man complained a palpable painless mass over his right arm for 1 month. Magnetic resonance imaging (MRI) showed a 14-cm mass with predominantly composed of fatty tissue between long and short heads of triceps muscle. There were some serpiginous structures with hyperintensity within the tumors on gradient-echo and gadolinium enhanced T1-weighted images. Histologic examination revealed a picture of intermuscular angioma predominantly composed of cavernous lymphangioma.
