	*~~Transverse hemisection~~ of spinal cord		*Hemisection (or unilateral compression) of the spinal cord
	*~~Unilateral~~ cord compression		*Pure Brown-Séquard is rare; most cases are ''Brown-Séquard plus'' syndrome with incomplete hemisection
			*Most common cause: penetrating trauma (stab wounds > gunshot wounds)
			*Other causes: [[spinal cord compression (non-traumatic)\|tumor]], [[epidural abscess]], [[epidural hematoma]], [[multiple sclerosis]], [[spinal cord infarction]]

	==Clinical Features==		==Clinical Features==
	*~~Decussation~~ of ~~corticospinal~~ tract ~~at the medulla and complete lack of~~ decussation ~~of fibers of the posterior columns result in~~:		*Classic pattern results from the anatomy of spinal tract decussation:
	**Ipsilateral spastic paresis		**'''Ipsilateral''' motor deficits: spastic paresis/[[weakness\|paralysis]] (corticospinal tract — decussates at medulla)
	**Ipsilateral loss of proprioception, vibration		**'''Ipsilateral''' loss of proprioception, vibration, and light touch (dorsal columns — decussate at medulla)
	*~~Decussation~~ of ~~anterolateral fibers within spinal~~ tract ~~one level up via~~ anterior white commissure ~~results in:~~		**'''Contralateral''' loss of pain and temperature (spinothalamic tract — decussates 1-2 levels above entry in anterior white commissure)
	**~~Contralateral loss~~ of ~~pain~~, ~~temperature (ie 'sensory dissociation')~~		*Ipsilateral [[Horner syndrome]] if cervical cord involvement
			*At the level of the lesion: ipsilateral LMN signs, band of ipsilateral anesthesia

	==Evaluation==		==Evaluation==
	*~~Clinical presentation~~ and ~~mechanism~~		*MRI spine — imaging modality of choice to identify the lesion
			*CT spine if MRI not immediately available or if penetrating trauma
			*Neurological level assessment: motor, sensory (pinprick and light touch), rectal tone

	==Management==		==Management==
	{{Acute spinal cord injury treatment}}		{{Acute spinal cord injury treatment}}
			*Address underlying etiology (surgical decompression for compressive lesions, antibiotics for abscess)

	===Prognosis===		==Prognosis==
	*~~Good~~		*Best prognosis of all incomplete spinal cord syndromes
			*>90% of patients regain ambulatory function
			*Motor recovery typically begins within 1-6 months

	==Disposition==		==Disposition==
	*~~Admission~~		*Admit all patients — neurosurgery or spine surgery consult
			*ICU admission for high cervical lesions or hemodynamic instability
