Cervical intramedullary immature teratoma with metastatic recurrence in an adult.

STUDY DESIGN

Case report.

OBJECTIVES

We present for the first time an adult patient with cervical intramedullary immature teratoma with metastatic recurrence.

SETTING

Peking university Shenzhen Hospital, Shenzhen, China.

METHODS

A 30-year-old woman presented with rapidly progressive quadriplegia. Magnetic resonance imaging (MRI) revealed an intramedullary tumor occupying C1-C2 of the upper spinal cord. An urgent operation, consisting of decompression by laminectomy and tumor gross resection, was performed under a preoperative diagnosis of spinal glioma. The histological diagnosis was immature teratoma. The patient received local radiotherapy after gross total resection. The serum alpha fetoprotein (AFP) and human chorionic gonadotropin (HCG) levels were normal postoperatively, until these were evaluated on the 10th month with neurological deterioration. Metastatic recurrences were demonstrated on MRI with lesions located at the levels of C5-C6 and T11-12. Removal of the second tumors was performed and the pathological examination identified a malignant germ cell tumor (yolk sac tumor). The patient was then referred to chemotherapy and radiotherapy.

RESULTS

No tumor regrowth was encountered and the patient remained stable for 6 months after adjuvant therapy.

CONCLUSION

Immature teratoma should be included in the differential diagnosis of holocord tumors in the adult with rapidly progressing symptoms and if found should be radically excised if possible. Adjuvant therapy should be the salvage therapy for this recurrent tumor.
