MRI results ? Pain cause?
I got an MRI for pudental nerve entrapment due to my symptoms of rectal pain and itching. My symptoms are very strong but somehow I don’t have nerve entrapment? Insane?
TECHNIQUE: Multiplanar multisequence MRI of the lumbosacral plexus after administration of 5 cc of intravenous contrast.
FINDINGS:
Lumbosacral plexus: Normal course, morphology, and signal intensity of the lateral femoral cutaneous nerve, pudendal nerve,
obturator nerve, and posterior cutaneous nerve bilaterally.
Femoral nerves: Intact.
Sciatic nerves: Intact.
Muscles / Tendons:
Iliopsoas: Normal muscle signal. Unremarkable tendon.
Piriformis: Normal muscle signal.
Gluteal muscles:Normal muscle signal. Unremarkable gluteus medius and minimus tendons.
Hamstring tendon:Normal signal. Unremarkable hamstring tendons.
Joints:
Sacroiliac joints: Normal right sacroiliac joint. Mild edema along the left inferior margin of the sacroiliac joint laterally.
Pubic symphysis: Intact.
Hip joints: No hip effusion.
Bones: Normal marrow signal.
Vessels: Normal flow voids.
Abdomen / pelvis: No significant abnormality in the visualized posterior abdomen and pelvis.
OTHER: Susceptibility artifact from battery pack with leads extending through the left sacral neuroforamina and into the left
presacral space. Pelvic floor is low-lying; directed clinical assessment suggested for rectocele.
IMPRESSION:
1.\X09\Unremarkable lumbosacral plexus MRI without evidence of pudendal nerve entrapment.
2.\X09\Mild edema and enhancement of the left inferior lateral sacroiliac joint cord with mild sacroiliac anteriorly.
