ABSTRACT: An unusually enlarged Thymus is seen in superio anterior mediastinum interspersed between aorta and superior vena cava, observed in adult male cadaver during routine dissection. This finding could be mistaken as intrathymic lymph node. Thymus seems to appear at later half of fetal period but function of persistent enlarged Thymus is still unknown although it is assumed to play a different role in immune system than other peripheral lymph node. Such enlarged Thymus in adults can lead to clinical syndromes similar to superior and anterior mediastinum pressure symptoms.
