Radiation-induced cranial nerve palsy

Radiation-induced cranial nerve palsy: a cross-sectional study of nasopharyngeal cancer patients after definitive radiotherapy.

PURPOSE To address the characteristics and the causative factors of radiation-induced cranial nerve palsy (CNP) in nasopharyngeal carcinoma (NPC) patients with an extensive period of followed-up. PATIENTS AND METHODS A total of 317 consecutive and nonselected patients treated with definitive external-beam radiotherapy between November 1962 and February 1995 participated in this study. The med...

Capecitabine and sixth cranial nerve palsy.

Capecitabine is an oral chemotherapeutic agent converted to 5 fluorouracil (5-FU). Neurotoxicity associated with the medication encompasses both central and peripheral nervous systems. We describe a 60 year old man with colonic carcinoma who developed diplopia due to a sixth nerve palsy following the use of capecitabine which is an orally administered prodrug of 5-FU. An MRI of brain did not re...

Management of congenital fourth cranial nerve palsy.

Nasal cause of sixth cranial nerve palsy.

Anatomically the cavernous sinus is closely related to the sphenoid sinus and the nasopharynx. Sphenoid sinusitis, as demonstrated in the case can affect the nerves which are contained within it. Apart from the sinus, a direct extension from a nasopharyngeal lesion is commonly encountered to cause diplopia, owing to the sixth nerve involvement. The provisional diagnosis should be a nasopharynge...
