 To practice basic interpretation principles using selected diseases of the brain. The session is intended to reinforce the principles discussed during a previous hour of formal lecture.

 A collection of nine cases are presented below. However, it is highly unlikely to cover more than six cases in a one-hour discussion. MRI findings and conclusions will be discussed with active audience participation.

 For all cases, list your MRI findings and most likely diagnosis.
