Left Atrial Compression Secondary to Massive Esophageal Dilatation in a Patient With Idiopathic Achalasia.

• LA compression by esophageal dilatation in IA is a very rare condition. • Esophageal dilatation may compress mediastinal structures. • Echocardiography is valuable when a retrocardiac mass is suspected.

Volumetric brain analysis as a predictor of a worse cognitive outcome in Parkinson's disease.

Unlabelled: Cognitive impairment in Parkinson's disease (PD) results in significant morbidity and mortality being early diagnosis essential. Identification of patients who are at higher risk of developing cognitive impairment based only on clinical data is not sufficient. To this end, magnetic resonance imaging (MRI) with automatic segmentation, such as FreeSurfer, could be a useful tool with high accuracy because it has histological validation.

Correlation of MRI Visual Scales with Neuropsychological Profile in Mild Cognitive Impairment of Parkinson's Disease.

Few studies have evaluated magnetic resonance imaging (MRI) visual scales in Parkinson's disease-Mild Cognitive Impairment (PD-MCI). We selected 79 PD patients and 92 controls (CO) to perform neurologic and neuropsychological evaluation. Brain MRI was performed to evaluate the following scales: Global Cortical Atrophy (GCA), Fazekas, and medial temporal atrophy (MTA).
