Possible hydrocephalus status post left temporal tumor excision. 1-year-old female. The patient is status post left sided craniotomy. There is a large extra-axial fluid collection present also identified on 4/29 but not on 4/28. It measures 25 mm in width comparedThere is midline shift present with the shift of the third ventricle approximately 12 mm to the right of midline appeared there is a 90 x 20 mm cystic fluid collection in the left temporal lobe. There is associated intracranial air in the subdural and subarachnoid spaces.The right lateral ventricle is larger than the left lateral ventricle and the temporal horn is dilated but not substantially different than the prior exam. the right lateral ventricle measures 24 mm in width on the current exam as well as on the recent MRI exam.There is a right sided subdural collection measuring 7 mm in thickness.
1.Bilateral subdural effusions left larger than right associated with intracranial air.2.There is a cystic cavity in the left temporal lobe extending to the frontal lobe better demonstrated on the recent MRI3.There is midline shift present as described above4.Recent left frontal and temporal surgery.5.Enlargement of the right lateral ventricle and compression of the left lateral ventricle. The size of the ventricles has not changed since exam of 4/29.
