MRI of postamputation neuromas.
Magnetic resonance imaging of 24 symptomatic lower limb amputations revealed that postamputation neuromas were easily diagnosed in above-the-knee amputees. Visualization of nerve trunks in below-the-knee amputees was difficult due to greater compactness of calf muscles. Neuromas on magnetic resonance imaging appeared ovoid or rounded and were usually heterogenous and isointense with muscle. Magnetic resonance imaging also showed additional causes of stump pain such as scar formation, fat in atrophied muscles, soft tissue abscesses, osteomyelitis, and hematomas.
