Transient XXXX after perimesencephalic @entity548 : the role of enlarged temporal horns.

@entity1 @entity2730 @entity548 @entity510
OBJECTIVES: Although long term outcome of @entity1 with perimesencephalic @entity548 , a benign subset of @entity510 , is excellent, some @entity1 report an episode of @entity2730 for the first hours to days after the ictus. The relation between the occurrence of @entity2730 and the size of the ventricles on CT, including the temporal horns, were studied in @entity1 with perimesencephalic @entity548 . METHODS: Twenty seven consecutive @entity1 with perimesencephalic @entity548 were asked about the occurrence of @entity2730 . Age adjusted bicaudate indices and third ventricle sizes were calculated. Linear measurements of the temporal horn were taken in three directions: anterior-posterior, medial-lateral, and oblique. Additionally, enlargement of the temporal horns was assessed with the "naked eye". RESULTS: Ten of the 27 @entity1 reported an episode of transient @entity2730 ; in these @entity1 the mean sizes of the temporal horns were larger than in @entity1 without @entity2730 , ranging from a factor of 1.7 for the medial-lateral measurement to a factor of 2.3 for the anterior-posterior measurement. Most of the @entity1 with @entity2730 had relative bicaudate indices and relative third ventricle sizes> 1, and all had enlarged temporal horns at "naked eye" assessment. CONCLUSION: About one third of @entity1 with perimesencephalic @entity548 have an episode of @entity2730 shortly after the bleed. The occurrence of @entity2730 is associated with enlargement of the temporal horns, and might be explained by temporary hippocampal dysfunction.
