Spontaneous internal carotid artery dissection (sICAD) is an uncommon cause of isolated cranial nerve palsies. Commonly patients present with stroke, headache, facial pain and Horner's syndrome, with upto 16% having cranial nerve palsies. We present the case of a 55-year-old man who presented with hoarseness, dysphagia and tongue swelling, mimicking a tongue base tumor. He was found to have unilateral VIIth, Xth and XIIth nerve palsies with Horner's syndrome. Magnetic resonance imaging showed high signal changes and loss of signal void in right internal carotid artery, later confirmed by Angiography as a dissection with pseudo-aneurysm. He was started on anticoagulation and made a good recovery on discharge. This case presents a unique combination of cranial nerve palsies due to internal carotid artery dissection (ICAD) and to our knowledge is the first reported case in the literature. Early recognition and institution of appropriate therapy is critical to prevention of ischemic stroke.
