“…In addition, MRN can detect direct and indirect signs of neuropathy even in the absence of a detectable compressive cause, and aids in management and diagnosis by nding the precise site of injury, evaluating peripheral nerve contour, caliber, signal, fascicular disruption, and intralesional fat, etc., allowing the operator to grade the nerve injury to aid pre-operative assessment for the nerve surgeon [24] providing a comprehensive evaluation of the regional neuromuscular structures. This helps with the diagnosis since historically the identi cation of the inguinal nerves and their surrounding tissues was complex.…”

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.

Peripheral neuropathy is known to be one of the most common neurological disorders. Despite the great diagnostic value of electroneuromyography and ultrasound, diagnostics and differential diagnostics of peripheral nerves diseases of different origin could be challenging. Magnetic resonance tomography has been increasingly used in recent years to evaluate cases of suspected or established peripheral neuropathy with excellent results. Manuscript deals mainly with advantages and limitations of abovementioned diagnostic instruments, technical considerations according to different anatomy of peripheral nerves and state-of-the-art technical decisions, frequently used MRI-sequences and their diagnostic value based on own observation, recommendations for contrast enhancement use, different methods of fat suppression. Currently there is practically no standardized description of normal MRI features of peripheral nerves as well as their changes in different diseases, evaluation of images is based mainly on the radiologist experience, which obviously decreases methods diagnostic value. Studies of large numbers of healthy volunteers and patients with peripheral neuropathies of different origin are required to solve this problem.

Chronic pain is a frequent and notable complication after inguinal hernia repair, it has been extensively studied but its management and diagnosis are still difficult. 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 confirmation of the preoperative imaging findings. 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 finding 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.
