Abstract:
Schwannoma arising from cervical sympathetic chain is relatively uncommon and can be occasionally misdiagnosed as carotid body tumor. On MR images, schwannoma shows generally hypointense features on the T1-weighted images and hyperintense features on the T2-weighted images. Occasionally, however, contrast administration, which lets schwannoma show marked enhancement, may make it difficult to differentiate schwannoma from carotid body tumor. A 41-year-old woman presented a neck mass on the left. MR images of the neck and carotid angiography revealed a well-enhancing ovoid tumor, which separated the internal carptod arteries from the external carotid arteries at the level of carotid bifurcation. Complete tumor resection was performed and histopathology findings confirmed a schwannoma originating from the sympathetic chain. Postoperatively, miosis and facial anhydrosis of the left side were noted without ptosis, enophthalmos or other neurologic deficits. We report this case with a review of the literatures.
