Spontaneous Regression of a Hypoglossal Neurinoma: Case Report and Review of the Literature.

BACKGROUND: Hypoglossal neurinomas are very rare intracranial tumors. The management choices include surgery, as the gold standard, and radiosurgery or a combination of both. Little is known about this condition and the behavior of this tumor. CASE DESCRIPTION: A 54-year-old woman presented with a right 12th nerve neurinoma with ipsilateral hemiatrophy of the tongue and spontaneous regression after 1 year of follow-up. CONCLUSIONS: Our case highlights the importance of considering careful observation and diligent follow-up as a treatment option, as these lesions can show spontaneous regression with no invasive approaches.
