Cancer pain treatment currently consists of the administration of pain medications, radiation therapy, tumor ablation as well as neurolytic plexus blocks. Neurolytic plexus blocks target both sensory afferent fibers and sympathetic fibers innervating visceral organs. Finding the right block for a specific type and location of cancer-related pain is crucial for the successful control of pain. One such example is a ganglion impar block for perineal pain. We report a case of a patient with chronic severe perineal pain from vulvar cancer and multiple surgeries, for whom a ganglion impar block followed by neurolysis provided significant pain relief.
