The Thyroid Gland01:23

The Thyroid Gland

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
Primary Lymphoid Organs01:16

Primary Lymphoid Organs

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...
Development of the Lymphatic System01:15

Development of the Lymphatic System

The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
Graves Disease II: Pathophysiology01:24

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
The Parathyroid Glands00:59

The Parathyroid Glands

The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...
Sympathetic Pathways: Sympathetic Chain Ganglia01:20

Sympathetic Pathways: Sympathetic Chain Ganglia

The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...

Area of Science:

  • Endocrinology
  • Thoracic Surgery
  • Diagnostic Imaging

Background:

  • Substernal goiters can present diagnostic and therapeutic challenges.
  • Thyroid tissue extending into the mediastinum requires careful surgical planning.

Purpose of the Study:

  • To report a case of a substernal goiter with mediastinal extension.
  • To discuss the surgical management and potential origins of mediastinal thyroid masses.

Main Methods:

  • Pre-operative magnetic resonance imaging (MRI) for diagnosis and extent evaluation.
  • Surgical extraction via cervical incision followed by sternotomy for residual mediastinal mass.

Main Results:

  • Initial cervical extraction of substernal goiter.
  • Postoperative MRI revealed a residual mediastinal thyroid mass (8.5×9×10 cm).
  • Successful removal of the mediastinal mass via sternotomy.

Conclusions:

  • Mediastinal thyroid masses can arise from cervical thyroid tissue extension.
  • Multimodal imaging and staged surgical approaches may be necessary for complete resection.
