Ventrolateral pontomedullary junction ischaemic stroke imitating isolated facial nerve palsy


A 75-year-old woman presenting with unilateral lower motor neurone facial weakness was ultimately diagnosed with an ischaemic stroke at the pontomedullary junction affecting the facial nerve fascicles. Isolated, unilateral, upper and lower facial weakness is typically caused by lesions affecting the facial nerve, such as Bell’s palsy, though rarely can be a manifestation of acute ischaemic stroke. It is important for neurologists and emergency providers to determine appropriately which patients with facial weakness require neuroimaging and which do not.
