Abstract

Tongue paralysis due to isolated palsy of XII cranial nerve is uncommon neurological

finding. It is a multi-etiological condition, and may occur secondary to infectious mono- nucleosis. It is presented with characteristic signs e.g. reduced tongue movements with

deviation to the affected side on protrusion. The diagnosis is challenging and based on thorough clinical examination and laboratory and imaging findings. A case of 31year old Kuwaiti male, presented to emergency room at Mubarak Alkabeer Hospital-Kuwait, with infectious mononucleosis complicated with temporary unilateral hypoglossal nerve palsy is reported, with an emphasis that paralysis of cranial nerve may be due to a less severe systemic condition, and not necessarily associate an underling malignancy. To the best of our knowledge, hypoglossal nerve palsy complicating infectious mononucleosis has never been previously reported in Kuwait.
