Cubital tunnel syndrome is the second most common peripheral
neuropathy of the upper limb. This is due to the anatomy of the
tunnel, the physiological changes that the nerve undergoes during
elbow flexion, as well as pathological conditions that occur within
the tunnel. We present two cases of ulnar neuropathy occurring
at the level of the cubital tunnel, demonstrating that this entity
may occur owing to an identifiable cause or may show only signal
alteration without a visible cause on MRI.
