Letter to the Editor: Unilateral Aneurysmal Calcific Dilatation of an Extracranial Portion of the Internal Carotid Artery in a Patient with End-Stage Renal Disease

To the Editor, Aneurysmal dilatation of the extracranial portion of the internal carotid artery is rare. A middle-aged woman, a patient of chronic kidney disease secondary to amyloidosis, presented with fluid overload and abnormal blood biochemistry: hemoglobin of 7 g/dL, serum creatinine of 9 mg/dL, Ca × P product of 48 mg^2/dL^2 (10 × 4.8) and serum albumin of 3.7 g/dL, intact parathyroid hormone level of 121 pg/mL and 25 (OH) vitamin D of 19 ng/mL.. The chest X-ray of her neck and chest revealed proper position of the vascular access in addition to a calcified dilated right internal carotid artery (Figure 1).
