We present a first case of concurrent @entity5 consisting of @entity808 and @entity1653 arising at the same spinal level in a @entity1 without @entity4786 . A 49-year-old @entity1 without clinical evidence of @entity4786 presented with a 5-month history of right neck @entity158 . MRI demonstrated an @entity5 involving the right-sided C2 nerve root with a small intradural component. T1- and T2-weighted and contrast-enhanced MRI could not differentiate the @entity5 as different from the @entity5 . Total @entity5 was performed. No contiguity of the @entity5 with the @entity5 was seen. The @entity5 attached strongly to the dura mater around the C2 nerve root exits. Intraoperative pathological diagnosis confirmed the @entity5 as @entity808 and the @entity5 as @entity1653 . We therefore thoroughly coagulated the dura mater adjacent to the @entity5 and resected the dura mater around the nerve root exits together with the @entity5 . Pathological examination revealed that the resection edge of the extradural component consisted of a spinal nerve with thickened epineurium and was free of neoplastic cells. No @entity808 component was evident in the @entity5 . No obvious transition thus existed between the extra- and @entity5 . Distinguishing these @entity5 prior to surgery is critical for determining an optimal surgical plan, as @entity808 and @entity1653 require different surgical procedures. We therefore recommend a careful review of preoperative imaging with the possibility of concurrent @entity5 in mind.
