AI Article Synopsis
- - Granular cell tumor (GCT) is a rare, mostly benign growth, often found on the tongue, but can occur in nerve tissues, as seen in this case.
- - A 43-year-old man experienced neck pain and hand numbness, leading to the discovery of a tumor near his C2 nerve, which was surgically removed and diagnosed as GCT.
- - This case highlights the importance for surgeons to recognize GCT in spinal nerve root tumors, as it may require a different surgical technique than standard nerve sheath tumors.
Article Abstract
Background: Granular cell tumor (GCT) is a relatively uncommon predominantly benign lesion that usually presents as a solitary, painless cutaneous or submucosal nodule. Most of these tumors are found in the tongue. Although GCT is believed to have a Schwann cell origin, reports of GCT in peripheral and spinal nerves are uncommon.
Case Description: We report the case of a 43-year-old man with neck pain and hand numbness who was found to have a heterogeneously enhancing left-sided C2 nerve sheath tumor on magnetic resonance imaging. He underwent C2 decompression and resection of the left-sided C2 nerve sheath tumor with subsequent C1-C2 arthrodesis and instrumentation. Histopathologic review showed GCT. Review of the literature yielded 4 other reported cases of GCT within the vicinity of a spinal nerve root. Only one of these explicitly showed spinal nerve root involvement. This is a rare case of a GCT presenting as cervical nerve root mass, and what we believe is the first reported case of this in the literature.
Conclusions: The surgeon should be aware of GCT when encountering spinal nerve root tumors because it may alter the surgical approach necessary for adequate resection compared with more commonly encountered nerve sheath tumors.

: Charcot-Marie-Tooth (CMT) disease is an inherited peripheral neuropathy primarily involving motor and sensory neurons. Mutations in INF2, an actin assembly factor, cause two diseases: peripheral neuropathy CMT-DIE (MIM614455) and/or focal segmental glomerulosclerosis (FSGS). These two phenotypes arise from the progressive degeneration affecting podocytes and Schwann cells.

Background: A brachial plexus avulsion occurs when the nerve root separates from the spinal cord during birthing trauma, such as shoulder dystocia or a difficult vaginal delivery. A complete paralysis of the affected levels occurs post-brachial plexus avulsion. Despite being reported in 10-20% of brachial plexus birthing injuries, it remains poorly diagnosed during the acute stages of injury, leading to poor intervention approaches.

Complex regional pain syndrome (CRPS) is a chronic pain condition characterized by significant sensory, motor, and autonomic dysfunction, often following trauma or nerve injury. Historically known as causalgia and reflex sympathetic dystrophy, CRPS manifests as severe, disproportionate pain, often accompanied by hyperalgesia, allodynia, trophic changes, and motor impairments. Classified into type I (without nerve injury) and type II (associated with nerve damage), CRPS exhibits a complex pathophysiology involving peripheral and central sensitization, neurogenic inflammation, maladaptive brain plasticity, and potential autoimmune and psychological influences.

Objective: This study aimed to describe the anatomical landmarks for intervertebral disc (IVD) percutaneous approaches (transpedicular TPA and transannular TAA) using CT scans in humans and dogs for regenerative medicine research.
Method: CT scans of 57 human (30 supine, 27 prone) and 49 canine (29 chondrodystrophic, 20 non-chondrodystrophic) lumbar spines were analyzed. Morphometric data, cutaneous landmarks, and approach angles were measured, with additional sections assessing nerve root distances from TPA routes.

Lumbar intervertebral disc degeneration is thought to be the main cause of low back pain, although the mechanisms by which it occurs and leads to pain remain unclear. In healthy adult discs, vessels and nerves are present only in the outer layer of the annulus fibrosus and in the bony endplate. Animal models, and histological and biomechanical studies have shown that annulus tear or endplate injury is the initiating factor for painful disc degeneration.
