Alcock canal syndrome is a rare entrapment neuropathy of the pudendal nerve. We report a case of perineal neuralgia where pudendal nerve compression was due to fibrosis of the obturator internus muscle following an injury of the muscle. After being misdiagnosed for 2 years, the patient was diagnosed only after a combined neurophysiologic and magnetic resonance imaging (MRI) investigation. This case underlines the importance of performing focused neurophysiologic and neuroimaging studies in patients with neuropathic perineal pain in order to reach a correct diagnosis.

Abstract
Alcock canal syndrome is a rare entrapment neuropathy of the pudendal nerve. We report a case of perineal neuralgia where pudendal nerve compression was due to fibrosis of the obturator internus muscle following an injury of the muscle. After being misdiagnosed for 2 years, the patient was diagnosed only after a combined neurophysiologic and magnetic resonance imaging (MRI) investigation. This case underlines the importance of performing focused neurophysiologic and neuroimaging studies in patients with neuropathic perineal pain in order to reach a correct diagnosis.
