SECOND MRI REPORT
OREGON IMAGING CENTER
PATIENT NAME: POLISHCHUK, Katherin, DOB 15 Dec 2000, AGE: 004, SEX: F
EXAM DATE: 15 Sept 2005
ORDER PROVIDER: BRADSHAW, PILAR
MRI OF THE BRAIN WITH AND WITHOUT CONTRAST
1. 4.8 x 3.8 x 3.1 cm
mass arising from the pons is most consistent with a pontine glioma.
The overall size of the lesion is similar to the prior exam oof 8/11/05.
2. There is interval development of two enhancing nodules within the left
aspect of the lesion when compared to the prior exam.
INDICATIONS: Re-evaluate size of brain tumor.
Multiplanar MR imaging of the brain was performed with and without
contrast 3.5 cc of Magnevist.
SEDATION: The patient was given 90mg of Nembutal orally for sedation.
Continuous monitoring was performed by the nursing staff.
No adverse effects were noted.
FINDINGS: There is a 4.8 x 3.1 x 3.8 cm mass again identified arising from the pons.
This mass is predominantly hyperintense on the T2-weighted images.
There is interval development of a 1.2 x 1.0 x 1.5 cm irregular enhancing nodule at the inferior
left lateral aspect of the mass. There is an additional punctate area of enhancement at the superior
left aspect of the mass which was also not identified on the prior examination. The overall
size of the mass is similar to the prior study. There is expansion of the pons with effacement
of the prepontine cistern.
The basilar artery is displaced anteriorly by the mass; however a normal flow void is
The supratentorial structures remain within normal limits. There is no evidence of hydrocephalus
or extraaxial fluid collection. Normal gray/white differentiation is seen supratentorially.
The paranasal sinuses are well-aerated. No osseous destructive lesion is identified. No soft
tissue abnormality is seen. The included bones are within normal limits.
