RESUMEN
Diabetic lumbosacral radiculoplexus neuropathy is often confused with radiculopathy in the context of spinal degenerative disc disease including spinal stenosis. Accuracy in diagnosis may prevent unnecessary interventional procedures including selective nerve root blocks or epidural steroid injections or even surgery in selected cases. Our patient with known diabetes and lumbar disc disease presented with acute onset of pain in L5-S1 distribution of the left lower extremity. Initial MR imaging of the lumbar spine did not show sufficient structural changes to explain her symptomatology. An MR neurogram of the lumbosacral plexus revealed inflammation within the bilateral sciatic and femoral nerves; subsequent EMG demonstrated a generalized sensorimotor neuropathy but no evidence of plexopathy. To our knowledge, this is the first case report that utilized MR imaging of the pelvis to assist in the diagnosis of diabetic lumbosacral radiculoplexus neuropathy (DLRPN).

BACKGROUND: Aortic pseudoaneurysms are a rare cause of chronic back pain, usually resulting from compression of the adjacent neurovasculature. It is uncommon for patients with pseudoaneurysms of the abdominal aorta to present in a delayed fashion after initial traumatic injury. CASE DESCRIPTION: We describe an unusual case of delayed pseudoaneurysm formation with subsequent erosion into the adjacent L1 vertebral body. This pseudoaneurysm was secondary to a gunshot wound with retained ballistic fragment that had occurred 27 years previously. Herein, we discuss the patient's presenting symptoms, imaging, and overall treatment. In this particular case, we used a combined surgical and endovascular (hybrid) approach after the patient experienced recurrent low back pain, weeks after a primary endovascular treatment was performed. We additionally review the current literature on the management of aortic pseudoaneurysms causing vertebral body erosion and back pain. CONCLUSIONS: In our patient, a combined surgical and endovascular (hybrid) approach led to the complete resolution of his back pain symptoms and to complete exclusion of the pseudoaneurysm on follow-up imaging. Endovascular management of aortic pseudoaneurysms may be a reasonable alternative to open surgery in high-risk patients; however, this approach may result in a higher recurrence of pseudoaneurysm and initial presenting symptoms. Further investigation is needed to elucidate the efficacy of endovascular treatment of these lesions.
