Learning objectives
Following objectives are considered in relation to this article:
To identify cerebral hemi-atrophy and evaluation of associated factors with a systematic approach.
To emphasize the role of neuro-imaging findings associated with cerebral hemi-atrophy in establishing etiological diagnosis.
Background
Cerebral hemi-atrophy or unilateral cerebral atrophy is the term that describes the end result of various pathologies that result in the atrophy or hypoplasia of one cerebral hemisphere.
Cerebral hemi-atrophy encompasses wide spectrum of etiologies.
It is an uncommon condition which commonly involves paediatric age group.
CT and MRI are imaging modalities that are useful for the image-based neurological evaluation.
MRI is the preferred modality in assessment of the aetiology in cases of cerebral hemi-atrophy.
Clinical presentation varies in relation to the involved structures and...
Findings and procedure details
Magnetic resonance imaging studies were performed using 1.5 Tesla MR System using standard head coils.
CT imaging using dual source 16 slice CT scanner system was used in few cases.
A simple and systematic algorithmic approach was used for evaluation of these cases.
Algorithm for cerebral hemi-atrophy as given below [Figure 1]:
Identify the asymmetry of cerebral hemispheres.
Look for abnormal hemisphere based on size and sulcal prominence (Small hemisphere or Large hemisphere).
Look for ventricular size and volume of the abnormal side (Small or...
Conclusion
Imaging findings associated with cerebral hemi-atrophy help in formulation of etiological diagnosis.
Understanding the distinguishing neuro-imaging features of pathologies can assist in clinching the correct diagnosis and providing appropriate treatment protocol.
