Wasted tongue in neuromyelitis optica spectrum disorders due to hypoglossal nerve involvement

We report two cases of neuromyelitis optica spectrum disorder with hypoglossal nerve involvement resulting in a wasted tongue associated with other brainstem symptoms of hypogeusia, hypersalivation, hiccough, increased sweating, hyperemesis and myelitis (in the second patient). This occurred due to involvement of the hypoglossal, tractus solitarius and dorsal vagal nuclei. Though the myelitis and other brainstem signs recovered the hypoglossal nerve involvement resulting in a unilateral wasted tongue did not. It is important to consider neuromyelitis optica and its spectrum disorders in the differential diagnosis of a wasted tongue though its occurrence is rare.

Hypoglossal nerve tumor: A rare primary extracranial meningioma of the neck

Zulkiflee AB, Prepageran N, Rahmat O, Jayalaskhmi P, Sharizal T

We report a case of primary extracranial meningioma arising from the hypoglossal nerve in a 54-year-old man who presented with a 9-month history of hoarseness and progressive dysphagia. He had also noticed that his tongue was deviated to the left and, as a result, he was having difficulty pronouncing words. Examination revealed fasciculation and muscle wasting on the left side of the tongue. Other cranial nerve functions were normal. Contrast-enhanced computed tomography detected a heterogeneous mass that had arisen above the bifurcation of the left common carotid artery and had extended to near the skull base. Transcervical excision of the tumor was performed, and histopathology identified it as a meningioma of the hypoglossal nerve. The patient recovered uneventfully, and he was without recurrence at more than 2 years of follow-up. A primary extracranial meningioma is extremely rare, and its presentation may be subtle. A thorough investigation is necessary to avoid fatal compressive symptoms.

Fulltext Unilateral hypoglossal nerve palsy after the use of laryngeal mask airway (LMA) Protector

Tham LY, Beh ZY, Shariffuddin II, Wang CY

Korean J Anesthesiol, 2019 12;72(6):606-609.

PMID: 31304693 DOI: 10.4097/kja.d.18.00354

BACKGROUND: The laryngeal mask airway (LMAⓇ) ProtectorTM (Teleflex Medical Co., Ireland) is the latest innovation in the second generation of LMA devices. One distinguishing feature of this device is its integrated, color-coded cuff pressure indicator (Cuff PilotTM technology) which enables continuous cuff pressure monitoring and allows adjustments when necessary; this ensures patient safety due to better monitoring.

CASE: We report a case of postoperative unilateral hypoglossal nerve palsy after uncomplicated use of the LMA Protector. To the best of our knowledge, this could be the second reported case.

CONCLUSIONS: This case demonstrates that anesthetists need to routinely measure cuff pressure and that the Cuff PilotTM technology is not a panacea for potential cranial nerve injury after airway manipulation.
