CT appearances of the normal and abnormal thymus in childhood. 1987

T E St Amour, and M J Siegel, and H S Glazer, and S N Nadel

Computed tomography in 25 children with diseases of the thymus was evaluated to determine which features are the most useful in diagnosing thymic pathology. In each case thymic shape, density, and size, particularly thickness and width, were analyzed and compared with similar data in 71 normal children with no clinical evidence of thymic abnormality. Comparison showed that most thymic diseases altered normal thymic shape and contour, and hence evaluation of gross thymic morphology alone was adequate for recognition of abnormality. Although thymic thickness was a more reliable indicator of disease than width, this measurement was rarely required for diagnosing disease. The attenuation value of the thymus was helpful occasionally in suggesting a specific diagnosis.

D013945 Thymoma A neoplasm originating from thymic tissue, usually benign, and frequently encapsulated. Although it is occasionally invasive, metastases are extremely rare. It consists of any type of thymic epithelial cell as well as lymphocytes that are usually abundant. Malignant lymphomas that involve the thymus, e.g., lymphosarcoma, Hodgkin's disease (previously termed granulomatous thymoma), should not be regarded as thymoma.

D013950 Thymus Gland A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.
