title: Pudendal Neuralgia as the Initial Manifestation of Infiltrative Sacrococcygeal Chordoma.
abstract: Sacrococcygeal chordoma is a malignant tumour originating from remnants of the notochord. Chordomas are slow-growing tumours whose symptoms develop insidiously. We present the case of a 72-year-old woman with a 6-month history of genital pain radiating to the perianal area and exacerbating when she was in a sitting position. MRI and PET studies revealed a large mass in the sacrococcygeal region causing bone destruction and invasion of neurovascular structures. The immunohistochemical study of the surgical specimen determined it to be chordoma. This is the first published case of pudendal neuralgia as a form of presentation of sacrococcygeal chordoma.
