Subcutaneous lipoma compressing the common peroneal nerve and causing palsy: sonographic diagnosis.
The compression of peripheral nerves by benign fatty tumors has rarely been reported in the literature. We present the case of a patient who had a subcutaneous lipoma in the region of the knee that caused common peroneal nerve palsy and appeared to compress the nerve on sonography. The surgical removal of subcutaneous lipoma allowed complete recovery.
