Article Abstract
Thymic hyperplasia is frequently observed in Graves' disease. However, detectable massive enlargement of the thymus is rare, and the mechanism of its formation has remained elusive. This case showed dynamic changes in thymic hyperplasia on serial computed tomography images consistent with changes in serum thyrotropin receptor (TSH-R) antibodies and thyroid hormone levels. Furthermore, the patient's thymic tissues underwent immunohistochemical staining for TSH-R, which demonstrated the presence of thymic TSH-R. The correlation between serum TSH-R antibody levels and thymic hyperplasia sizes and the presence of TSH-R in her thymus suggest that TSH-R antibodies could have a pathogenic role in thymic hyperplasia.

While improving quality of life (QOL) is the focus of MG management, multifactorial determinants of QOL impairment remain unclear, especially in socioeconomically underrepresented regions, particularly Southwestern China. This study aimed to explore myasthenia-specific risk factors for QOL and develop a parsimonious prediction model.

Mediastinal masses in children often raise concern for malignant conditions, particularly lymphoma. The thymus, which is normally prominent in infants and young children, begins its physiological involution around the age of six to seven years; however, this process is gradual and can extend into adolescence. Thymic hyperplasia beyond this age is uncommon, and it can mimic a mediastinal tumor on imaging.

We treated a 43-year-old woman with Graves' disease (GD), complicated by thymic hyperplasia. Routine chest radiography revealed an abnormal opacity, and computed tomography revealed an anterior mediastinal tumor. At the initial visit to our institution, blood tests revealed hyperthyroidism with positive thyroid-stimulating hormone receptor antibodies, confirming the diagnosis of GD.

Less than 10% of primary hyperparathyroidism (PHPT) patients have supernumerary parathyroid glands. In a 52-year-old man with multiple endocrine neoplasia type 1 (MEN 1) syndrome with PHPT, integrated 18F-Fluorocholine PET/4D-CT (FCH PET/4D-CT) was done for localization of parathyroid adenoma. FCH PET/4D-CT revealed 5 culprit lesions (1 ectopic) along with FCH avid nonenhancing anterior mediastinal mass, possibly NET or thymoma.
