Case Reports
Isolated unilateral hypoglossal nerve paralysis caused by an atlanto-occipital joint synovial cyst.
An isolated unilateral hypoglossal nerve lesion is an uncommon cranial nerve palsy. We report a case of isolated hypoglossal nerve paralysis caused by an intra-dural synovial cyst. To our knowledge, this is the first reported case of a twelfth nerve paralysis caused by a synovial cyst. The anatomy of the hypoglossal nerve, its blood supply and the relationship of the nerve to the atlanto-occipital joint are reviewed, along with the common causes of isolated hypoglossal nerve paralysis.

The implanted peripheral nerve stimulator has a role for pain relief in well-selected patients with pain in a peripheral nerve distribution. We describe an electrode to help simplify the surgical implantation of a peripheral nerve stimulator and also to reduce the possibility of electrode migration following implantation. Design details of the electrode are discussed, as are notes on surgical technique.

Schwannomas are rare benign tumours of nerve sheath cells of neural crest origin. Often these tumours are solitary and encapsulated. ⋯ We report an extremely rare case of schwannomatosis of the sciatic nerve in a young female and include a comprehensive literature review. Treatment options are discussed.

Painful neuromas form on cutaneous nerves as a result of trauma, pressure, stretch or entrapment. Since the earliest descriptions of neuromas, proposed treatments have been met with poor results and controversy. ⋯ As veins are readily accessible due to their proximity in the neurovascular bundle, they serve as a ready source for grafting. The advantages include minimisation of trauma to bone and muscle as compared with previous treatment techniques and the relative ease of the method.
