PURPOSE: @entity145 are sometimes encountered in MRIs performed for a variety of reasons. In @entity1 with @entity302 , particularly those with @entity302 , @entity145 are often assumed to be related to their @entity410 focus. We conducted a study to investigate this putative relationship. METHODS: A retrospective study on the incidence of @entity145 was performed in @entity1 seen in our @entity302 Clinic who had CT or MRI scans, interictal EEGs or ictal EEGS. Locations of @entity410 foci in these @entity1 were defined from clinical and electrophysiologic data. RESULTS: Seventeen of 867 @entity1 had @entity145 . Twelve @entity1 had temporal lobe cysts and only 3 of them had temporal lobe @entity410 . Four @entity1 @entity75 and only 1 had @entity410 ipsilateral to the cyst. One @entity1 had a cerebello-pontine angle @entity410 . Thus, clinical manifestations of @entity410 and EEG findings (interictal and/or ictal) indicated that the @entity410 focus was adjacent to the cysts in only 4 @entity1 (23.5%). CONCLUSIONS: Our findings suggest that @entity145 are often an incidental finding in @entity1 with @entity302 and do not necessarily reflect the location of the @entity410 focus.

What is the relationship between XXXX and @entity410 foci?
