| Final diagnoses included one bronchogenic cyst and one combined bronchogenic cyst and thymic hyperplasia. |
| Rare cases of thymomas, thymic carcinomas, and lymphomas have been reported. |
| The systemic immune effects include increased apoptosis of thymocytes, decreased macrophage phagocytosis, thymic atrophy and diminished allograft rejection. |
| After partial decerebration, the thymic cortical and medullary compartments diminished markedly in size. |
| Most of these lesions arise as a consequence of migrational defects during thymic embryogenesis. |
| Histological findings included lymphoid depletion and thymic and adrenal atrophy. |
