Giant Inflammatory Cervical Ganglion Due to Ectopic Rib Head: Report of a Rare Diagnosis Mimicking a Cervical Schwannoma

Abstract

Cervical schwannomas may be common in patients with cervicobrachialgia. We report a case of an apparent C8 schwannoma in a 55-year-old female that was discovered to be an inflammatory enlarged cervical ganglion. Such a rare presentation may be explained by the particular conformation of the left C7-Th1 neuroforamen, compressed by an ectopic cranially located first rib head, which was visible only with a cervical computed tomography scan. No similar finding is reported in the literature, and this interesting case may provide new insight into the differential diagnosis of cervical spinal lesions.
