Pudendal neuralgia

Sira Carrasco García de León, José Manuel Flores Barragán, Natalia Villasanti Rivas
Sacrococcygeal chordoma is a malignant tumour originating from remnants of the notochord. Chordomas are slow-growing tumours whose symptoms develop insidiously. We present the case of a 72-year-old woman with a 6-month history of genital pain radiating to the perianal area and exacerbating when she was in a sitting position. MRI and PET studies revealed a large mass in the sacrococcygeal region causing bone destruction and invasion of neurovascular structures. The immunohistochemical study of the surgical specimen determined it to be chordoma...

Pudendal neuralgia is being increasingly recognized as a cause of chronic pelvic pain, which may be related to nerve injury or entrapment. Due to its complex anatomy and branching patterns, the pudendal nerve abnormalities are challenging to illustrate. High resolution 3 T magnetic resonance neurography is a promising technique for the evaluation of peripheral neuropathies. In this article, the authors discuss the normal pudendal nerve anatomy and its variations, technical considerations of pudendal nerve imaging, and highlight the normal and abnormal appearances of the pudendal nerve and its branches with illustrative case examples...

Pudendal nerve entrapment syndrome is an unusual cause of chronic pelvic pain. We experienced a case of pudendal neuralgia associated with a ganglion cyst. A 60-year-old male patient with a tingling sensation and burning pain in the right buttock and perineal area visited our outpatient rehabilitation center. Pelvis magnetic resonance imaging showed the presence of multiple ganglion cysts around the right ischial spine and sacrospinous ligament, and the pudendal nerve and vessel bundle were located between the ischial spine and ganglion cyst at the entrance of Alcock's canal...

A variety of neuromodulation approaches have been described for the management of pelvic neuropathies, including interstitial cystitis, pudendal neuralgia and persistent genital arousal disorder. The benefits of a combined sacral and pudendal nerve neuromodulator has yet to be explored for these patients. In this report, we describe the case of a 35-year-old woman with a complex pelvic neuropathy resulting in urinary, sexual and gastro-intestinal dysfunction. She presented with an established diagnosis of interstitial cystitis; however, she also fulfilled diagnostic criteria for pudendal neuralgia and persistent genital arousal disorder...

Persistent pain after vaginal mesh surgery is a rare and agonizing entity that has devastating consequences for the patient's quality of life. Many etiologies have been blamed including nerve injuries and entrapments. Pudendal neuralgia is a rare chronic neuropathic pain syndrome in the anatomical territory of the pudendal nerve. Various treatment options, such as medication management, physiotherapy, nerve blocks, decompression surgery and neuromodulation, have been used, but the most appropriate treatment for pudendal neuralgia has not yet been determined...

BACKGROUND: Pudendal neuropathy is a tunnel syndrome characterized by pelvic pain and may include bowel, bladder, or sexual dysfunction or a combination of these. One treatment method, pudendal nerve perineural injections (PNPIs), uses infiltration of bupivacaine and corticosteroid around the nerve to provide symptom relief. Bupivacaine also anesthetizes the skin in the receptive field of the nerve that is injected. Bupivacaine offers rapid pain relief for several hours while corticosteroid provides delayed pain control often lasting 3 to 5 weeks...

Pudendal neuralgia is a chronic neuropathic pelvic pain that is often misdiagnosed and inappropriately treated. The Nantes criteria provide a basis for the diagnosis of pudendal neuralgia due to pudendal nerve entrapment. The 5 essential diagnostic criteria are pain situated in the anatomical territory of the pudendal nerve, worsened by sitting, the patient is not woken at night by the pain, and no objective sensory loss is detected on clinical examination. The fifth criterion is a positive pudendal nerve block...

AIMS: Pudendal neuralgia is the clinical expression of a chronic compression of the pudendal nerve. The diagnosis is based on a set of five criteria, called Nantes criteria. Four of the criteria are clinical and the last requires evaluation of the anesthetic response to CT-guided infiltration of the pudendal nerve. The aim of our study is to evaluate the relevance of anesthetic test response to select patients for surgery, and whether this criterion can be used to predict its success...

Chronic pelvic pain is a condition that can be caused by pudendal neuralgia, interstitial cystitis, piriformis syndrome and neuropathy of the ilioinguinal, iliohypogastric and genitofemoral nerves. Based on three case reports this article discusses the clinical effectiveness of pulsed high-frequency radiofrequency (PRF) treatment applied to the pudendal nerve under ultrasound guidance in medicinally treated patients with chronic pelvic pain.

Pudendal neuralgia is characterized by chronic pain or discomfort in the area innervated by the pudendal nerve, with no obvious cause. A successful pudendal nerve block is crucial for the diagnosis of pudendal neuralgia. Blind or fluoroscopy-guided pudendal nerve blocks have been conventionally used for diagnosis and treatment; however, ultrasound-guided pudendal nerve blocks were also reported recently. With regard to the achievement of long-term effects, although pulsed radiofrequency performed under fluoroscopic guidance has been reported, that performed under ultrasound guidance is not well reported...

BACKGROUND: Conscious external anal sphincter contraction is mediated by the pudendal nerve. Pudendal neuropathy is, therefore, believed to result in fecal incontinence. Until urge sensation is experienced, fecal continence is maintained by unconscious external anal sphincter contraction, which is regulated by the anal-external sphincter continence reflex. The innervation of unconscious contraction is yet unknown. OBJECTIVE: We aimed to determine whether unconscious contraction is mediated by the pudendal nerve and whether age influences unconscious contraction...

Chronic pelvic pain is defined as disabling pain of at least six months duration. Chronic pelvic pain has often multiple causative factors. Careful analysis of clinical history and detailed clinical examination must be carried out to guide further imaging investigations. Endometriosis is a common cause of chronic pelvic pain, although there is no correlation between the severity of lesions and pain intensity. Pelvic ultrasonography should be the first line imaging examination to search for causative conditions that include endometriosis, adenomyosis, pelvic varices and chronic infection...
