case_images: Two linear masses were palpated in the longitudinal direction on the dorsal side of the left forearm of the patient (Figure 1).
case_images: Ultrasound of the forearm in the short-axis view showing a normal compressible right cephalic vein (A,B) and a non-compressible left cephalic vein, indicating vein thrombosis (C,D).

case_images: The long-axis and short-axis ultrasound confirmed an oval-shaped mass with a homogenous echogenicity filling the left cephalic vein (Figure 2).
case_images: Doppler ultrasound of the left forearm shows an obstructive, ovoid, and hypoechoic mass in the long-axis view (A) and short-axis view (B). Thrombus (arrow) is filling the lumen of the cephalic vein, with the absence of a Doppler signal at its location.

case_images: In addition, when the lesion was compressed with a probe, unlike the opposite forearm showing a normal collapse of the vein, there was no change in the shape of the vein, indicating thrombi in the cephalic vein (Figure 3).
case_images: T2-weighted coronal section (A), T1-weighted coronal section (B) with contrast enhancement, and T2-weighted axial section (C) of the left forearm MRI. Non-enhancing low signal lesion (arrows) suspected to be thrombus located in the cephalic vein of the left forearm, extending 12 cm long.

case_images: A 12-cm-long mass without enhancement, filling the cephalic vein in the longitudinal direction, was identified confirming SVT at the forearm, without any other soft tissue pathologies (Figure 4).
