MASSIVE THYMIC HYPERPLASIA SECONDARY TO GRAVES DISEASE
AACE Clinical Case Reports
|June 12, 2020
Summary
Graves disease can cause massive thymic hyperplasia, a rare condition. Radioiodine therapy effectively reduced thymic hyperplasia in a patient with Graves disease, highlighting a non-surgical treatment option.
Area of Science:
- Endocrinology
- Thoracic Surgery
Background:
- Graves disease (GD) is frequently associated with thymic hyperplasia.
- Massive thymic hyperplasia in GD is rare, with limited documented cases.
Observation:
- A 24-year-old female presented with symptoms of hyperthyroidism and a large anterior mediastinal mass.
- Diagnostic workup confirmed Graves disease and revealed significant thymic hyperplasia.
Findings:
- Radioiodine therapy for Graves disease resulted in a 76% reduction in the thymic mass volume.
- Thyroid function normalized, and hyperthyroid symptoms resolved post-treatment.
Implications:
- Radioiodine therapy can be an effective non-surgical treatment for massive thymic hyperplasia associated with Graves disease.
- This case expands the understanding of thymic pathology in GD and its management.

01:23The Thyroid Gland
6.3K
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...

4.7K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

00:59The Parathyroid Glands
4.1K
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...

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...

01:20Synthesis and Regulation of Thyroid Hormones
6.8K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
