Popis: | Occipital neuralgia is a painful condition affecting the posterior scalp in the distributions of the greater occipital nerve (GON), lesser occipital nerve (LON), third occipital nerve (TON), or a combination of the three. Scalp masses can be a cause of occipital neuralgia if they originate from neural components, but their incidence is low and preoperative diagnosis may be difficult. Among benign tumours of peripheral nerves, there is a group originating from Schwann cells. We report a rare case of a GON schwannoma causing occipital neuralgia. A 52-year-old Chinese lady presented with 6 months of daily headaches mainly in the left occipital region, with no other associated symptoms. Physical examination was normal. CT scan showed a left occipital mass for which she underwent surgical excision for. Intra-operatively, the mass was noted to be deep to the muscles arising from a nerve. Upon review of the pre-operative scan, this nerve was most likely the GON. Histology subsequently came back as a schwannoma. To the best of our knowledge, this is likely to be the 5th reported case of GON schwannoma causing occipital neuralgia. Keywords: Schwannoma, Greater occipital nerve, Occipital neuralgia |
