case_images: MRI image of a wrist Schwannoma mimicking an intraneural ganglion cyst. A well-defined ovoid structure lateral to the extensor carpi radialis tendon, measuring 6 x 5 mm and communicating with the underlying joint space. (A) Sagittal, (B) Coronal, and (C) Transverse view.

case_images: To diagnose the lesions, he underwent both hand ultrasound and MRI, and the radiological characteristics were consistent with cystic lesions (Figure 1).
case_images: An intraoperative image of a schwannoma in the wrist shows a well-circumscribed tumor located on the superficial radial nerve. The image was obtained during the surgical procedure for excision of the tumor. Panel (A) shows two separate, well-defined oval masses adhered to the superficial radial nerve. Panel (B) shows the nerve after excision of both tumors, as the nerve showed continuity without disruption. (C) shows a gross picture of both lesions after removal.

case_images: In the operating room, when the skin was cut open, and the lesions were first exposed, they exhibited a gross appearance that was more consistent with Schwannoma tumors, with no cystic material emerging on aspiration (Figure 2).
case_images: Typical schwannoma with palisaded wavy nuclei on a myxoid background, without mitotic activity (hematoxylin-eosin, 1003).
