Tuberculosis is increasing in prevalence in North America, mainly due to HIV infection. We describe an unusual case of TB of the thymus in a HIV sero-negative Filipino immigrant who preoperatively was thought to have a thymoma. We describe the clinical, radiologic and pathologic findings and review the literature on TB of the thymus.

W15 Limiting MRI to the area of interest to shorten image acquisition time is essential. A long image acquisition makes successful breath-holding difficult, with resultant motion artifact significantly compromising image evaluation. Hyperventilating the patient before each breath-hold can be helpful. Oxygen administration has been shown to be even more

Toxicologic Pathology, 2006
The thymus is a primary lymphoid organ that manifests dynamic physiological changes as animals age in addition to being exquisitely sensitive to stress and toxic insult. It is typically the first lymphoid tissue to respond to immunotoxic xenobiotics, with the first change being loss of cortical lymphocytes by apoptosis.

Journal of Thoracic Imaging, 1999
Thymic neoplasms are a common cause of an anterior mediastinal mass and may be benign or malignant. Thymic cysts are congenital or acquired and may be associated with a thymic malignancy. True thymic hyperplasia and thymic lymphoid hyperplasia may enlarge the thymus and simulate a neoplasm.

Immunology Today, 1984
The thymus has fascinated immunologists since the discovery that it influenced the maturation of T lymphocytes. However, only within the past five years have investigations of the thymus progressed beyond descriptive histology or functional studies performed at the population level.

Archives of Pediatrics & Adolescent Medicine, 1956
DEVELOPMENT and expansion of thoracic surgery has increased the frequency with which tumors and cysts of the thymus are encountered. This has led to greater need for observation and study of anatomy, physiology, and pathology of the thymus in order to elucidate the poorly understood subject of diseases of the thymus.

Chest Surgery Clinics of North America, 2001
Technologic advances in imaging, particularly CT and MR imaging, have revolutionized the ability to noninvasively image the thymus. Increasing knowledge of the normal and pathologic states of the thymus has been accompanied by an increasing ability to depict morphologic alterations in this gland with fine spatial resolution and can even provide ...

Survey of Immunologic Research, 1985
Macrophages are a major population of thymic cells along with lymphocytes and epithelial cells. They are distributed in an apparently random manner throughout the cortex and medulla. Thymic macrophages express all of the various identifying characteristics associated with macrophages throughout the body including expression of a high level of class-I ...

Proper development of the thymus is critical for an individual to acquire full immune capability. A full complement of the components that participate in thymic development, interacting with each other at the correct time, is required for maturation.
