Heterotopic calcification can occur as a result of secondary or tertiary hyperparathyroidism.1 Herein we describe a patient with end-stage renal disease who has had several episodes of facial palsy bilaterally. Clinical evaluation, medical testing, radiographic imaging, and, finally, surgery revealed facial nerve compression secondary to dural calcification. An extensive literature search demonstrated that dural calcifications resulting in facial paralysis has not been previously described to our knowledge.
