Figure 1.
Conventional radiography of the left elbow reveals a nodular soft tissue opacity proximal to the medial epicondyle (arrow).
Figure 2 A‑C.
Magnetic Resonance Imaging shows an oval‑shaped, well‑defined nodule in the subcutaneous tissue. A. The lesion appears isointense to muscle on T1‑weighted images (arrow) and B. is hyperintense on fatsuppressed T2‑weighted images (arrow). C. After intravenous administration of gadolinium contrast, there is vivid, homogeneous enhancement of the lesion (arrow), in keeping with a vascular tumor.
Figure 3 A.
Ultrasound shows a subcutaneous hypoechoic nodule.
Figure 3 B.
There is retro‑acoustic enhancement and high vascularization on color Doppler.
