Name of the Patient : Abc Xyz Slmn / M / 16 yrs.
Referred by : Dr. Abc Xyzasde.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

Patient has neurofibromatosis.
C/O seizures since 2 years.

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 and Fast Scan (T2 *) 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.

FEW IMAGES SHOW PATIENT MOTION.

OBSERVATION :

Areas of hyperintensity on all the pulse sequences are seen within the globus pallidus bilaterally (? abnormal myelination, ? hamartomatosis/heterotopic tissue). These do not enhance following contrast administration.

A well-defined lesion having a diameter of approximately 1.5 cms is noted within the medial aspect of the left temporal lobe. It is hyperintense on the proton and T2 Weighted images and shows enhancement following contrast administration.


A smaller lesion having a diameter of approximately 8.00 mms is seen within the collicular plate (midbrain) on the left side. This lesion does not enhance after contrast administration.

Both the 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.

IMPRESSION :

The MRI features are suggestive of :

1. Areas of hyperintensity on all the pulse sequences within the globus pallidus (? abnormal myelination, ? hamartomatosis/heterotopic tissue).

2. A lesion having a diameter of approximately 1.5 cms within the left temporal lobe, medially, may represent a hamartoma/glioma. A follow-up scan may be worthwhile.

3. A lesion having a diameter of approximately 8.0 mms within the collicular plate (midbrain) on the left side may represent a hamartoma.

These changes may be seen with neurofibromatosis Type I.
