We hypothesized that C7 or T1 root lesions (with a pre\u2010 or postfixed plexus) or cervical myelopathy might explain some \u201cC8 radiculopathies\u201d without C8 root compression. <jats:italic>Methods<\/jats:italic>: Retrospective analysis of cervical neuroimaging in 31 consecutive patients with EMG\u2010confirmed C8 radiculopathy. <jats:italic>Results<\/jats:italic>: Five patients (16%) had C8\u2010root compression at C7\/T1. Of those without C8\u2010root compression, 5 (16%) had C7\u2010root compression at C6\/7, one (3%) had T1\u2010root compression at T1\/T2, 7 (23%) had cervical cord compression at or above the C6\/7 level, 4 (13%) had intramedullary cervical lesions, and 9 (29%) had mild or nonspecific findings. <jats:italic>Conclusions<\/jats:italic>: C8 radiculopathy without C8\u2010root compression may be due to C7\u2010root compression in the setting of a \u201cprefixed\u201d brachial plexus, upper cervical cord compression with vascular compromise of the distal cervical spinal cord (\u201cmyelopathic hand\u201d), or intramedullary cervical cord lesions.
