Figure 2. 2 A. T2 axial, 1B. T1 axial, 1 C. T1 coronal, and 1D. T2 coronal magnetic resonance imaging of the left wrist demonstrating abnormal enlargement with mixed signal involving the median nerve just proximal to the carpal tunnel (yellow arrow). Note the coaxial cable-like appearance on the coronal imaging and honeycombing on the axial consistent with fibrolipomatous hamartoma.

Figure 4. Intraoperative image of the left wrist. Tenosynovectomy is performed demonstrating extensive tenosynovitis (yellow arrow). The flexor tendons underlying the tenosynovium are seen in the bed of the wound (blue arrow). The retractor at the bottom of the image is protecting the median nerve from inadvertent injury.

Figure 5. Intraoperative image of the left wrist. The median nerve is seen with an abnormal fusiform mass (yellow arrow). Micro-instrumentation is used to reveal the underlying mass to further assess for possible removal.

Figure 6. Intraoperative image of the left wrist. The median nerve is positioned on a background with fibrolipomatous hamartoma demonstrated next to the measuring utensil. Neurolysis of the epineurium has been performed and the mass is seen to be intimately associated with the underlying fascicles preventing excision.
