[The anterior choroidal artery syndrome]

Area of Science:

• Neurology
• Neuroimaging
• Vascular Neurology

Background:

• The anterior choroidal artery syndrome is an exceptionally rare neurological condition.
• Complete syndrome involves hemiplegia, hemianaesthesia, and homonymous lateral hemianopsia.
• Incomplete forms and associated neuropsychological disorders are also recognized.

Purpose of the Study:

• To describe the clinical presentation and diagnostic features of anterior choroidal artery syndrome.
• To correlate anatomical findings with clinical manifestations.
• To discuss associated neuropsychological deficits.

Main Methods:

• Case study analysis.
• Review of diagnostic imaging (computerized tomography).
• Correlation of lesion location with neurological and neuropsychological deficits.

Main Results:

• Computerized tomography reveals low-density areas in the posterior internal capsule, involving the pallidum tip.
• Lesions correspond to the anterior choroidal artery territory.
• Associated deficits include neglect syndrome and speech disorders depending on lesion laterality.

Conclusions:

• Anterior choroidal artery syndrome is characterized by specific neuroanatomical lesions.
• CT imaging is crucial for diagnosis.
• Understanding lesion-deficit correlations aids in managing this rare condition.
