IntroductionIntraspinal teratomas associated with congenital scoliosis are extremely rare, especially in an elderly adult.Materials And MethodsWe report the seventh case of intraspinal extramedullary teratoma coexisting with congenital scoliosis in a patient older than 50 years, possibly the oldest patient documented in literature. A 56-year-old male suffered from low back pain that increased with calf numbness and foot weakness. Conventional radiography showed a congenital scoliosis due to incomplete segmentation of the L2 and L4 vertebras, and magnetic resonance images revealed a heterogeneous intraspinal extramedullary mass located at L4-S1.ResultsThe tumor was totally removed, and was confirmed as a mature teratoma on biopsy. The patient remains asymptomatic at 34-month follow-up.ConclusionsRare intraspinal teratoma should be included in the differential diagnosis of intraspinal mass, especially in patient with congenital scoliosis. Patient with mature teratoma may survive with out any symptoms in the long term. Progressing neurological deficit is a main indication for surgery. Excellent clinical outcomes could be achieved by surgical resection and dural sac decompression.
