Resection of an intramedullary high cervical metastasis from a malignant mixed Muellerian tumour

We present a 66-year-old female patient with a high cervical intramedullary metastasis from a malignant mixed Muellerian tumour (MMMT; carcinosarcoma) with concomitant syringomyelia. She was admitted to our clinic with symptoms of cervical myelopathy. MRI revealed an intramedullary tumour of 2.6cm×1.2cm at the cervical vertebral body C2. We performed a laminectomy on C2 followed by a dorsal median myelotomy from C1 to C3 to resect the tumour. The surgical intervention removed the tumour completely and resolved the syringomyelia. During the 36months of follow-up, the patient presented in a stable condition with no evidence of tumour recurrence. To our knowledge, this is the first report of an intramedullary metastasis of a MMMT.
