(Table 1), and the diagnosis of the acute unilateral manifestation includes the potential involvement of a neurovascular event in the affected side. For example, vasculitis of the feeding artery presents with necrosis of the tongue with severe pain and swelling. As a masquerading representation of angioedema, spontaneous dissection of the cervical area of the internal carotid artery can manifest as acutely painless swelling of the unilateral tongue, with a predilection for hypertensive individuals. Acute denervation of the hypoglossal nerve can lead to an increase in the capillary bed in the tongue muscles or a fluid shift to the extracellular matrix, resulting in oedema in the unilateral tongue. Ryan and colleagues reported a patient with a 3 hour history of painless unilateral tongue swelling without paralysis in the acute phase of hypoglossal neuropathy due to spontaneous dissection of the internal carotid artery.
