THIRD MRI REPORT
OREGON IMAGING CENTERS
POLISHCHUK, Katherine
DOB 12/15/2000
Date of Service: 10/21/2005 10:33 AM
Order Provider: BRADSHAW, PILAR, MD
(OIC) - MR BRAIN WO CONTRAST
PRELIMINARY
Signs and Symptoms: Brain tumor.
MRI OF THE BRAIN WITHOUT CONTRAST
IMPRESSION:
1.
The pontine mass appears relatively stable in size, however there has been
slight iterval increase in the enhancement portion in the left side of the
mass.
2.
Stable ventricular size without evidence of hydrocephalus.
HISTORY: Four year old female with brain tumor.
TECHNIQUE:
Multi-sequence, multi-planar MR images are obtained of the brain prior to
and following intravenous administration of 3.5 cc of Magnevist contrast. The
patient was sedated during the procedure with 70 mg of Nembutal.
COMPARISON: Prior study from 9/15/05.
FINDINGS:
Ventricular size is stable. There is no evidence of hydrocephalus.
The pons is expanded by an infiltrating mass. It is predominantly
hyperintense in the T2 and FLAIR sequences. It is similar in size to the
prior study, measuring approximately 4.8 x 3.4 x 3.6 cm in transverse, AP
and craniocaudal dimensions respectively. The mass extends into the
prepontine cistern and infiltrates into the left cerebellar
peduncle. Following gadolinium administration there is an enhancing
portion in the left lateral aspect of the mass. This has increased
slightly in size since the prior study. The enhancing portion measures
approximately 19.2 x 14.5 mm (previously 14.4 x 14.8 mm at a similar
level).
The vascular artery is anteriorly displaced and the mass envelopes the artery
nearly completely. This appearance is similar to the prior study.
There are flow voids in all of the major vascular structures, indicating
patency.
Mild mucosal thickening is seen in the maxillary sinuses.
