Cerebral toxoplasmosis


It is not uncommon to not be aware of the immune state of a patient at the time of imaging, either because lab results are still pending or because the information has not been passed on along with the imaging request. It is thus essential to keep that possibility in mind. 

This is a fairly typical appearance for Toxoplasmosis and would certainly be the favored diagnosis if the patient was known to be immunocompromised.
