Perineal neuralgia is characterised clinically by pain (burning type of perineal pain) exacerbated in the sitting position. It is secondary to impairment of the internal pudendal nerve in its musculo-osteo-aponeurotic tunnel composed by the ischium and the obturator internus muscle (ischiorectal fossa or pudendal canal). As in any nerve tunnel syndrome, pre-existing neuropathy constitutes a predisposing factor and should therefore be identified. The diagnosis of pudendal tunnel syndrome is confirmed by perineal electrophysiological investigations (detection of neurogenic muscles of the perineal floor, increased sacral latency). Treatment consists of infiltration, possible repeated, of the pudendal tunnel with a sustained-release corticosteroid under CT guidance.
会阴神经痛的临床特征为疼痛（会阴烧灼样疼痛），坐位时会加重。它继发于阴部内神经在由坐骨和闭孔内肌组成的肌骨 - 腱膜隧道（坐骨直肠窝或阴部管）中的损伤。与任何神经隧道综合征一样，既往存在的神经病变是一个易感因素，因此应该被识别出来。阴部管综合征的诊断通过会阴电生理检查（检测会阴底部的神经源性肌肉、骶部潜伏期延长）得以证实。治疗包括在CT引导下用缓释皮质类固醇对阴部管进行浸润，可能需要重复进行。
