Figure 10. A, B.

High-resolution grayscale and color Doppler ultrasound of the forearm, in a 53-year-old patient with painless tumor in the front of the forearm, without a history of trauma. A round tumor of less than 1 cm iso/hypoechogenic mass in grayscale was observed, moderately delimited, with an attached vessel that nourished the lesion. An important signal Doppler was observed. Due to signs of suspicion, such as heterogeneity, high vascularity, and a very important Doppler signal, an MRI was requested, which showed a well-defined, rounded, 1 cm image, with hypersignal in T1, leading to a metastatic lesion. MRI, magnetic resonance imaging.
