The thymus is an important lymphatic organ; plays an essential vital role in the development and maturation of the immune system during childhood. • Our Objectives in this exhibit are :- - To review the normal anatomy and embryology of the thymus gland. - To enumerate the differential diagnosis of the focal and diffuse lesions of thymus gland in the pediatric patient. - To illustrate the imaging features of such lesions and increase awareness and recognition of uncommon lesions.  

- 1. Embryological development of the thymus gland : 2. Normal anatomy of the thymus gland throughout the different age stages of life:- 3. Imaging features of the different disorders affecting the thymus at the pediatric age group: A. congenital lesions as:- Congenital absence of the thymus ( Di-Goarge syndrome.) B: Benign lesions including:- - Thymic cyst , - Thymlipoma , - Rebound thymic hyperplasia - Ectopic parathyroid adenoma within the thymus. C: Malignant thymic lesions including:- - Germ cell tumor, - Thymic lymphoma - Deposits within the thymus. In conculsion: - Lesions of the thymus, both diffuse and focal, in a pediatric patient encompass wide range of differential diagnosis;. Thus the proper orientation and accurate diagnosis help in proper treatment of these patients.
