14y MC Akita cross with progressive right pelvic limb lameness. There is a small well‐demarcated ovoid mass in the plantar aspect of the proxi-
mal metatarsus, which is T1 hypo intense, T2 isointense, and STIR hyperintense compared to adjacent tissues (a–c: arrowhead). The mass is in
the location of the superficial and deep digital flexor tendons. The mass, confirmed to be a grade II malignant peripheral nerve sheath tumor,
was surgically excised (d: arrowhead), which required dissection away from the digital flexor tendons.
