Name of the Patient : Abc Xyza lmn / F / 9 mnths.
Referred by : Dr. Abc Xyzdar / Dr. Abc Xyzarmar.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O delayed milestones.
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
3 mm thick T1 Weighted and T2 Weighted coronal images.
5 mm thick T1 Weighted sagittal images.
Ill-defined, hyperintense signal on the proton and T2 Weighted images in the periventricular white matter bilaterally, more on the right side and in the right centrum semiovale, most likely represents unmyelinated white matter fibres.
There is mild to moderate dilatation of both the lateral ventricles. The septum pellucidum is not visualized. The third ventricle and the frontal horns of the lateral ventricles are well differentiated. The interhemispheric fissure is well formed. The corpus callosum is also well identified, but appears thin, probably the result of ventricular dilatation. The left optic nerve is well identified. The right optic nerve is also seen and is smaller than the left.
The head of the caudate nucleus, thalamus and the lentiform nucleus on the right side appear hypoplastic as compared to the left.
The fourth ventricle and posterior fossa are unremarkable.
The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
The MRI features suggest absence of the septum pellucidum with dilated lateral ventricles, hypoplastic head of the caudate nucleus, thalamus and the lentiform nucleus on the right side, well differentiated frontal horns and the anterior interhemispheric fissure and a small right optic nerve. Septo-optic dysplasia should be ruled out. Lobar holoprocencephaly is less likely.
