	All cranial nerves should be assessed in the workup of Villaret to rule out other cranial nerve involvement (potentially leading to a different diagnosis). Cranial nerves IX, X, XI, and XII are expected to be weak or paralyzed, as well as an ipsilateral Horner's syndrome.

	=== Laboratory Tests ===		=== Laboratory Tests ===
			Laboratory testing may not be necessary in patients with a low index of suspicion for infectious causes. In patients where you suspect an infectious etiology, such as osteomyelitis of the skull base, routine infectious laboratory workup is warranted:
			* Complete blood count (CBC) with differential
			* C-Reactive Protein (CRP) / Erythrocyte Sedimentation Rate (ESR)
			* Blood cultures

	=== Imaging ===		=== Imaging ===
			In many instances, patients will already have a CT Brain at the time of ENT consultation to rule out a central cause of their cranial nerve deficits. MRI of the skull base with and without contrast will be the ideal imaging modality in most neoplastic causes of Villaret syndrome. For patients with a traumatic etiology, CT skull base will identify any fractures or bone chips resulting in the nerve palsies. Consider CT angiogram of the carotid system if there is trauma to the skull base as there may be concomitant injury to the carotid canal.

	=== Differential Diagnosis ===		=== Differential Diagnosis ===
	There are several named syndromes differentiating the various cranial nerve deficits that can result from skull base masses and lesions. These should be considered based on cranial nerve involvement.
