1/7. A multifocal neurinoma of the hypoglossal nerve with motor paralysis confirmed by electromyography.A rare case of neurinoma in a 72 year-old Japanese woman derived from the hypoglossal nerve is reported. The tumour was composed of three interconnected nodules occurring simultaneously in the left submandibular and sublingual regions. The lesion, which presented as a neck mass, caused a slight left-sided hemiparesis of the tongue with tongue deviation to the affected side not noticed by the patient. An electromyographic (EMG) study revealed decreased muscle activity on the left side of the tongue muscle, indicating dysfunction of the hypoglossal nerve. EMG was useful for diagnosis.- - - - - - - - - - ranking = 1keywords = paralysis (Clic here for more details about this article) |
2/7. Isolated hypoglossal nerve palsy due to skull base metastasis from breast cancer.We describe a 44-year-old woman who presented with an isolated unilateral hypoglossal nerve paralysis caused by a skull base metastasis from breast cancer. The patient had a modified radical mastectomy followed by local radiotherapy and adjuvant chemotherapy. Fourteen months later she presented with difficulty in speaking. physical examination revealed an isolated left hypoglossal nerve paralysis. The MRI scan showed a mass lesion involving the left occipital condyle extending into hypoglossal canal.- - - - - - - - - - ranking = 0.5keywords = paralysis (Clic here for more details about this article) |
3/7. hypoglossal nerve paralysis following tonsillectomy.While tonsillectomy is the commonest operation performed by otolaryngologists, paralysis of the hypoglossal nerve following tonsillectomy is not well recognized in the otolaryngology text or literature. We report a case of hypoglossal nerve paralysis following tonsillectomy and discuss the theories on the pathoaetiology as described in the predominantly anaesthetics literature. The likely causes of nerve injury are described and precautions are suggested to help avoid this problem.- - - - - - - - - - ranking = 1.5keywords = paralysis (Clic here for more details about this article) |
4/7. A case report of unilateral hypoglossal neuroparalysis resulting from horizontal subluxation in the atlanto-occipital joint due to rheumatoid arthritis.We experienced a case of unilateral hypoglossal neuroparalysis, in which the right hypoglossal nerve was compressed by horizontal subluxation in the atlanto-occipital joint, due to rheumatoid arthritis. This report represents a very rare case of unilateral hypoglossal neuroparalysis, in which diagnostic imaging of CT with multiple cross-sectional images (three-dimensional CT) was quite useful for the identification of compression by horizontal subluxation.- - - - - - - - - - ranking = 1.5keywords = paralysis (Clic here for more details about this article) |
5/7. Extracranial internal carotid artery aneurysm presenting as symptomatic hypoglossal and glossopharyngeal nerve paralysis.Aneurysms of the extracranial portion of the internal carotid artery are rare, particularly in young patients. They usually develop following trauma, or secondary to infection involving the parapharyngeal space that extends to the vessel wall. This is a case of an internal carotid artery aneurysm presenting acutely following chiropractic neck manipulation with hypoglossal and glossopharyngeal nerve palsy. The imaging findings and subsequent operative management are described.- - - - - - - - - - ranking = 1keywords = paralysis (Clic here for more details about this article) |
6/7. Asymmetric tongue muscle uptake of F-18 FDG: possible marker for cranial nerve XII paralysis.A 58-year-old woman, with nonsmall cell carcinoma, had multiple metastasis on 2-F-18 FDG positron emission tomography imaging. The right hemitongue had increased activity as compared with the left. This was not the result of the presence of a metastasis to the tongue, as shown by a negative computed tomography scan of the region and failure to demonstrate a lesion over a period of weeks. Uptake was likely related to right hemiglossal muscle activity. This was made more apparent by decreased uptake on the opposite side of the tongue (up to the midline) as a result of left cranial nerve XII paralysis.- - - - - - - - - - ranking = 1.25keywords = paralysis (Clic here for more details about this article) |
7/7. A patient with an odontoid fracture and atrophy of the tongue: a case report and systematic review of the literature.BACKGROUND: Traumatic hypoglossal nerve palsy is a rare entity and has rarely been described in association with an odontoid fracture. CASE DESCRIPTION: We present a patient with a posttraumatic odontoid fracture who developed selective weakness of his arms and a unilateral hypoglossal nerve palsy. A systematic review of the literature is presented, and hypothetical causes for the injury are discussed. CONCLUSION: Bell's cruciate paralysis and central cord syndrome are probably expressions of the same mechanism rather than 2 separate entities based on a preferential damage of pyramidal crossing arm fibers. C2 fractures with concomitant lower cranial nerve injury are relatively rare and have a reasonably good outcome, especially when unilateral.- - - - - - - - - - ranking = 0.25keywords = paralysis (Clic here for more details about this article) |
