“…MRI Neurography (MRN) presents as a useful resource for the radiologic evaluation of peripheral nerves. It is a tissue-speci c imaging technique, which depicts mechanical distortion of nerves, abnormal hyperintensity related to nerve irritation/entrapment, edema, discontinuity or neuroma in cases of injury, the relation of nerves to space-occupying lesions, and con rms neuropathy by depicting secondary muscle denervation changes [12]. This case series highlights the utility of MRI neurography in evaluating the damage to inguinal nerves after a hernia repair, with surgical con rmation of the preoperative imaging ndings.…”

Chronic pain is a frequent and notable complication after inguinal hernia repair, it has been extensively studied but its management and diagnosis are still di cult. The cause of chronic pain following inguinal hernia surgery is usually multifactorial. This case series highlights the utility of MRI neurography (MRN) in evaluating the damage to inguinal nerves after a hernia repair, with surgical con rmation of the preoperative imaging ndings.A retrospective review was performed on patients who underwent inguinal mesh removal and triple denervation of the groin. Inclusion criteria included MRI Neurography. All patients underwent surgical exploration of the inguinal canal for partial or complete mesh removal and triple denervation of the groin by the same senior surgeon.A total of nine patients who underwent triple denervation were included in this case series. MRN was then performed on 100% of patients. The postoperative mean VAS score adjusted for all patients was 1.6 (SD p), resulting in a 7.5 score difference compared to the preoperative VAS score (p). Since chronic groin pain can be a severely debilitating condition, diagnosis and treatment become imperative.MRN can detect direct and indirect signs of neuropathy even in the absence of a detectable compressive cause aids in management and diagnosis by nding the precise site of injury, and grading nerve injury to aid pre-operative assessment for the nerve surgeon.Thus, it is a valuable diagnostic tool to help with the diagnosis of nerve injuries in the setting of post-inguinal hernia groin pain.
