II. Pathophysiology

  1. Paralysis of superior cervical Sympathetic Nerve
    1. Destructive lesion to superior cervical Ganglion
    2. Destruction in posterior retroparotid space
    3. Mediastinal tumor or superior Lung Mass
  2. Lesions interrupt sympathetic fibers as they course to the Carotid Artery and then to the orbit
  3. Associated lesions
    1. Cranial Nerve 9
    2. Cranial Nerve 10
    3. Cranial Nerve 11
    4. Cranial Nerve 12

III. Causes

  1. Brainstem Stroke
  2. Posterior retroparotid space mass
    1. Parotid Gland tumor
    2. Carotid body tumor
    3. Metastatic tumor
    4. Lymphoma
    5. Tuberculous Adenitis
  3. Mediastinal Mass
  4. Apical Lung Lesion (e.g. Pancoast Tumor)

IV. Signs

  1. Mnemonic: Miosis, Ptosis, Anhidrosis
  2. All findings are unilateral
  3. Miosis
  4. Palpebral Ptosis (Incomplete)
    1. Contrast with complete Ptosis in levator paralysis
    2. Illusion of eyeball recession (No true enophthalmos)
  5. Absence of sweating (Anhidrosis) on face and neck

Ontology: Horner Syndrome (C0019937)

Definition (MSHCZE) Typ periferního vegetativního syndromu, vyvíjí se při lézi horního krčního sympatiku segmentu C8-Th1 (Budgeova ciliospinálního centra) – poškození míšních kořenů, ramus communicans albus, ganglion cervicale craniale a plexus caroticus. Klinicky se projeví ptózou, miózou, enoftalmem, hyperhidrózou a hypertermií na příslušné straně tváře. CBH syndrom se může rozvinout i při poškození jader v hypothalamu a v mozkovém kmeni, je pak součástí pontinního syndromu. Tento syndrom se někdy nazývá zánikový sympatikový syndrom. Srov. Hornerova triáda. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI_NCI-GLOSS) A condition in which one side of the face is flushed, does not produce sweat, and has a constricted pupil and drooping eyelid. It can be caused by an injury to, or paralysis of, nerves in the neck, or by a tumor.
Definition (MSH) A syndrome associated with defective sympathetic innervation to one side of the face, including the eye. Clinical features include MIOSIS; mild BLEPHAROPTOSIS; and hemifacial ANHIDROSIS (decreased sweating)(see HYPOHIDROSIS). Lesions of the BRAIN STEM; cervical SPINAL CORD; first thoracic nerve root; apex of the LUNG; CAROTID ARTERY; CAVERNOUS SINUS; and apex of the ORBIT may cause this condition. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp500-11)
Definition (CSP) syndrome associated with defective sympathetic innervation to one side of the face, including the eye; clinical features include miosis, mild blepharoptosis, and hemifacial anhidrosis (decreased sweating); lesions of the brain stem, cervical spinal cord, first thoracic nerve root, apex of the lung, carotid artery, cavernous sinus, and apex of the orbit may cause this condition.
