Horner syndrome: Difference between revisions

Latest revision as of 06:12, 27 November 2021

Scheme showing sympathetic and parasympathetic innervation of the pupil and sites of a lesion in Horner's syndrome.

Involves lesion anywhere along the sympathetic tract:
- Central (Hypothalamus, brainstem, spinal cord)
- Preganglionic (Pulmonary apex)
- Postganglionic (Superior cervical ganglion, ICA, skull base, cavernous sinus)

Left-sided Horner's syndrome

CXR
CT brain
CT Angiography head and neck, MRI, or MRA if concern for carotid artery dissection
