Case Reports[Pontine hemorrhage as a cause of peripheral facial paralysis].
Bell's palsy is the most frequent type of peripheral facial nerve paralysis. Nevertheless there are other less frequent causes of peripheral facial palsy, among which, we can find lesions in the brain stem affecting the seventh cranial nerve nucleus or its fibers. These lesions of the pons which paralyze the muscles of the face are often accompanied by lesions to other structures in the vicinity of the nucleus. We present the case of peripheral facial nerve palsy caused by hemorrhage in the pons, seen both on brain CT-scan and MRI, which affected the nucleus of the seventh cranial nerve and was not accompanied by any other clinical manifestations due to lesions of structures placed in the vicinity of this nucleus.
