title: Failure of the isthmus lobe to fuse in the midline.
abstract: Four developmental anomalies of the thyroid gland are to be noted: a pyramidal lobe, failure of the lobes of thyroid tissue to develop, failure of the isthmus to fuse, and absence of a significant part of the lateral lobes. We encountered failure of the isthmus to fuse in the midline of the thyroid gland in a 48-year-old female cadaver.
