Brain mapping for a stereotactic biopsy. Enhanced head CT:80 cc of Omnipaque 350 is administered for this exam.Stealth infused head CT with 1 mm slice thickness is obtained. Reformatted images are also acquired. This exam is performed with patient with stereotactic frame on head.Examination again demonstrates a large area of CSF collection in the right posterior frontal -- parietal region (likely result of prior partial lobectomy) with suggestion of subtle enhancing mass along its anterior edge similar to prior MRI exam from 4 -- 29 -- 2011. Extensive vasogenic edema in the left posterior frontal -- parietal is also again noted. There is an internal focus of enhancement measuring 14.9 x 19.5-mm in size.No evidence of an additional focus of enhancement.Stable size of ventricular system and no midline shift.
Stereotactic Stealth pulse infused T2 of the brain demonstrate two foci of enhancement one along the anterior aspect of right posterior temporal -- parietal lobectomy and a second one in the right posterior parietal similar to prior MRI exam.
