Background Information: A broad range of clinical diagnoses may result in basal ganglia abnormalities identified on imaging studies. Recognition of these abnormalities and providing a succinct, accurate differential diagnosis to ordering providers is a necessary skill for not only specialty-trained neuroradiologists, but also general radiologists as the frequency of the abnormalities is sufficiently high. This exhibit reviews the imaging anatomy of the deep gray structures on cross-sectional imaging and delineates the range of pathology seen in this location.

Educational Goals/Teaching Points: Participants will become familiar with the anatomy of the deep gray nuclei on multiplanar imaging, identify pathologic findings within the basal ganglia, develop a succinct and accurate differential diagnosis for basal ganglia abnormalities detected on brain CT and MRI.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: We review anatomy of the deep gray nuclei on multiplanar imaging, and review several basal ganglia pathologic processes including fundamental imaging features to help develop a succinct and accurate differential diagnosis.

Conclusion: The basal ganglia may be involved with a broad range of pathologic processes including toxic, metabolic, infectious, and vascular insults. Recognizing the normal anatomy and imaging appearance of the deep gray nuclei, in addition to possessing a basic familiarity with the various conditions found in this region, can help radiologists provide a succinct and accurate differential diagnosis for clinicians to guide clinical management.
