Head and Neck MRI Imaging Performed Safely in a Patient with Sacral Neuromodulation Device: A Case Report

Abstract

Introduction: Sacral neuromodulation is a well-established treatment option to manage refractory lower urinary tract and pelvic floor disorders. The technique involves implantation of a lead and an internal pulse generator that delivers electrical impulses to modulate the sacral area. Many patients worldwide have been implanted with MRI-non-compatible devices. Currently, MRI head only can be performed safely in these patients. Therefore, we present a case report of a patient who underwent MRI of the head as well as neck in the presence of a sacral neuromodulator without serious complications. Case Report: A 33-year-old lady known to have systemic lupus erythematosus, refractory overactive bladder, and recurrent urinary tract infection started complaining of right sided neck pain for 3 months in which she required MRI of the head and neck to further assess the nature of the pain. The patient was already implanted with sacral neuromodulator with excellent outcome to manage her refractory overactive bladder. Following careful discussion with the patient and radiologist, MRI study was conducted at 1.5 tesla and total procedure duration was 8 minutes for T1, T2 sagittal and axial cuts. The patient revealed feeling minimal tingling of the right lower limb and mild lower back pain during MRI, all of which disappeared once the study was terminated. Device was functioning well afterwards. Conclusion: MRI may be feasible for certain sacral neuromodulation patients under certain conditions without any serious adverse events.
