•Understand normal and abnormal human development causing the ectopic 
        tissues or organs. 
•Recognize clinical and radiological features of these ectopic tissues 
        focusing on the anatomical correlations and genetic factors.
•Identify the complications, the differential diagnoses and key findings of the 
        ectopic tissues for the correct diagnosis.

Table of contents
I.Introduction to human development
         From zygote to each organ:
         How does the ectopic tissue or heterotopic tissue develop? 
         Signaling pathway and gene mutations which cause malformations or 
         affect the development of organ systems.
II.Normal and abnormal human development, with the aspect of diagnostic 
        radiology
        : divided into five areas. Brain, Head and neck, Chest, Abdomen, Bone and 
        soft tissue.
III.Case based review
