title: Thymic carcinoma presenting with an unusual and delayed metastasis to the neural foramen, mimicking thoracic spinal radiculopathy.
abstract: We report a case of metastatic thymic carcinoma which presented as an enhancing mass located in the neural foramen of the thoracic spine. More common tumours which arise in the neural foramen would include a neurogenic tumour or developmental anomalies such as a foregut duplication cyst. This case is singular firstly because the lesion present as radiculopathy which mimics a neurogenic tumour. Secondly, the presentation was unusually delayed as the patient presented to our centre more than a decade after the resection of the primary tumour in another institution.
