Name of the Patient : Abc Xyz lmn / M / 29 yrs. Referred by : Dr. Abc Xyzmany.Examination : M.R.I. of the Brain.CLINICAL PROFILE : Patient has been operated upon for a right frontal SOL (low grade astrocytoma) on 00.00.00.C/O headaches with heaviness of the head since 1 month.
For follow up.EXAMINATION :M.R.I. of the brain was performed using the following
parameters :5 mm thick T1 Weighted, Proton and T2 Weighted axial images.5 mm thick FLAIR coronal images.
After administration of contrast, the following parameters were used :5 mm thick T1 Weighted axial and coronal images with magnetization transfer.5 mm thick T1 Weighted sagittal images.OBSERVATION :A right frontal craniotomy is noted with post-operative changes.There are ill-defined hypointense areas in the right frontal region which are seen to follow CSF signal on all the pulse sequences. These represent areas of cystic encephalomalacia, the sequelae of previous surgery. Resultant slight pull of the right frontal horn towards the operative area is noted. Ill-defined, hyperintense signal on the proton, T2 Weighted and FLAIR images is also noted in the frontal cortex around the above described lesion which may represent gliotic changes/?? residual tumor infiltration. ..2/.
The left lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.After contrast administration, there is no area of abnormal enhancement in the brain parenchyma or the meninges.
IMPRESSION :The MRI features are suggestive of :1. Post-operative status. 2. Areas of cystic encephalomalacia in the right frontal region, the sequelae of previous surgery.
3. Altered signal in the frontal cortex around the cystic encephalomalacic area may represent post-operative gliotic changes, ?? residual tumor infiltration.As compared to the previous MRI (study no:0000) dated 00.00.00 there is no significant change.
