1- To know the anatomy of the infrapatellar fat pad of Hoffa. 2- To know the different aspects on imaging of the normal infrapatellar fat pad of Hoffa. 3- To know the main diseases that can affect the infrapatellar fat pad of Hoffa and their main imaging features.

1 – Normal anatomy of the infrapatellar fat pad of Hoffa. 2 - Normal imaging aspects of the infrapatellar fat pad of Hoffa. a- Radiography ; b- Ultrasonography ; c- CT-scan ; d- MRI. 3 – Main diseases : 1- Mass syndrome : a- Cystic lesions : i.
