[Symmetrical and bilateral basal ganglia calcification. Case series and literature review].

INTRODUCTION

Symmetric, bilateral basal ganglia calcification is rare finding that sometimes occurs asymptomatically. Its prevalence increases with age, and the most affected site is the globus pallidus.

REPORT OF CASES

A series of seven cases with clinical and imaging diagnosis of basal ganglia calcification, recorded during the 2012 to 2016 period at the Department of Internal Medicine of the Hospital Civil de Guadalajara "Fray Antonio Alcalde, is presented. Most common clinical presentation was with altered alertness, headache and seizures. There was one case with movement disorders; there were no cases identified with dementia or tetany.

CONCLUSION

Ganglia calcification can be associated with age-related neurodegenerative changes, but it can be an initial manifestation of a variety of systemic pathologies, including disorders of the calcium metabolism, intoxication by different agents, and autoimmune and genetic diseases. Correlation of typical imaging findings with clinical manifestations and laboratory results should be established to reach a definitive judgment.
