Objective: To investigate the morphological structure and variation of thyroid gland in fetuses. Formalin fixed 40 aborted fetuses from 16weeks -36 weeks of gestational age were dissected to study the morphology of fetal thyroid glands. Crown -Rump length, and weight of the fetus along with fetal thyroid morphological and morphometric parameters were recorded. We observed the broader right lobes, broader left lobes of the thyroid glands, pyramidal lobe, levator glandulae thyroidae and isthmus agenesis which may consider under multiple morphological anomalies of the thyroid gland. The morphological parameters of the both broader right and left lobes of the thyroid glands of the fetuses were recorded. This study highlights various developmental anomalies of the thyroid gland, thereby forming a corner stone to safe and effective surgery. rd ring of trachea. There may be variations in its size and situation. (3) An anastomosis of superior thyroid artery is present along the upper border and inferior thyroid veins along lower border. The thyroid gland is covered by a thin fibrous sheath, the capsule of the thyroid. The anterior layer is continuous with pretracheal fascia and postero-laterally continous with the carotid sheath. The gland is covered anteriorly with infrahyoid muscles and laterally with the sternocleidomastoid muscle. On the posterior side, the gland is fixed to cricoids and tracheal ring cartilages and cricopharyngeus muscle by a thickening of the fascia to form the posterior suspensory ligament of thyroid gland also known as ligament of berry. Two parathyroid glands usually lies on each side between the two layers of the capsule, at the back of thyroid lobes.(4) Over the next few weeks, it migrates to the base of the neck, passing in front of the hyoid bone. During migration, the thyroid remains connected to the tongue by a narrow canal, the thyroglossal duct. At the end of the fifth week the thyroglossal duct degenerates and the detached thyroid continues on to its final position over the following two week. Persistence of pyramidal lobe, thyroglossal cysts, agenesis of the thyroid gland and aberrant thyroid are the major developmental anomalies of the thyroid gland (5). Accessory nodules or ectopic thyroid tissue of the thyroid are usually found at the embryonic origin of thyroid gland, at the foramen caecum, or on the lingual duct and thyroglossal tract within the tongue. (2,7) anomalies of the development of the thyroid gland distort the morphology of the gland may cause clinical functional disorders and various thyroid illnesses (6).
