RESUMO
OBJECTIVE: To report the clinical features of 9 patients with both abducens nerve palsy and postganglionic Horner syndrome. PATIENTS AND METHODS: Nine patients with this symptom combination were examined by our Neuro-ophthalmology Clinic in Nihon University Itabashi Hospital between 1978 and 2004. Patient ages ranged from 28 to 63 years (average 47.2+/-8.7 years). Six patients were males and 3 were females. Primary diseases, accompanying symptoms and prognoses were surveyed. RESULTS: In primary diseases, neoplasm in the cavernous sinus was observed in 2 patients, sphenoidal sinus cyst in 2, intra-cavernous carotid aneurysm in 2, epipharynx carcinoma in 1, chordoma in the base of the skull in 1, and meningioma in the middle cranial fossa in 1. Five patients with extra-cavernous sinus lesions; sphenoidal sinus cyst, epipharynx carcinoma, chordoma and meningioma, complained of severe headache. However, in patients without severe headache, intra-cavernous sinus lesions such as carotid aneurysm and metastatic carcinoma were detected. After therapy, abducens nerve palsy improved in 5 patients, however, Horner syndrome persisted in all patients. CONCLUSION: We emphasize that this symptom combination is an important sign of lesions in the posterior portion of the cavernous sinus or in its vicinity. Moreover, the presence or absence of severe headache depends on whether the lesion is in the intra-cavernous or extra-cavernous sinus.
