The superior cluneal nerve is a pure sensory cutaneous nerve and dominates sensation in the low back and buttock area. Entrapment of superior cluneal nerve around the iliac crest, superior cluneal neuropathy, is one of the etiology of low back pain or buttock pain, but diagnosis and treatment are still challenging. Here, we report a case that the buttock pain from cluneal nerve entrapment was diagnosed and treated by percutaneous interventions. Our patient, in this case, complained of chronic buttock pain that lasted for 6 months, and there was no response to the epidural block, medial branch block, and sacroiliac joint block, but the pain was relieved through the superior cluneal nerve block, and it was diagnosed as superior cluneal nerve entrapment neuropathy. The pain could be treated through nerve block and pulsed radiofrequency therapy. Buttock pain can be induced in many diseases, and accurate diagnosis cannot be made only by imaging studies and physical examination. Two or more diseases can simultaneously cause similar symptoms. Although superior cluneal nerve entrapment causes severe buttock pain, among several causes, it is difficult to diagnose superior cluneal nerve entrapment as the cause first. It is suggested that superior cluneal entrapment neuropathy could be considered as one of the causes in patients with buttock pain.
