White matter hyperintensity presence, quantity, and location exhibits no association with motor and non-motor manifestations of PD.

Introduction: Nonspecific areas of brain white matter hyperintensity (WMH) are commonly found in the elderly. Some studies have shown that the presence, quantity, and location of WMHs may be associated with the development of cognitive and motor decline in patients with Parkinson's disease (PD), but the results remain controversial. This study aimed to evaluate the relationship of WMH to motor and non-motor symptoms, including dysautonomia and rapid eye movement sleep behavior disorder (RBD), in patients with PD.

Brain MRI and magnetic resonance spectroscopy findings in patients with hyperargininemia.

Background And Purpose: Hyperargininemia (HA) is a rare autosomal recessive metabolic disorder and the neuroimaging features of this disease have seldom been reported. Hyperammonemic encephalopathy is uncommon in HA, and the clinical presentation of HA is distinct from other urea cycle disorders. This paper describes the brain MRI findings and a magnetic resonance spectroscopy (MRS) study of a series of Brazilian HA patients.

Imaging features of chronic expanding hematoma in the soft tissues of the hand simulating an aggressive lesion: case report.

A chronic expanding hematoma can persist and increase in volume for more than 1 month after the first hemorrhage. It is rare, uncommon in the hand, little known among physicians, and an imitator of malignancy. Our purpose was to report a case of this condition in the soft tissues of an 8-year-old girl's hand that simulated an aggressive lesion, and to conduct a review on this subject.

Craniofacial findings in fibrodysplasia ossificans progressiva: computerized tomography evaluation.

Objective: The aim of this study was the evaluation by using computerized tomography (CT) of craniofacial abnormalities in fibrodysplasia ossificans progressiva (FOP) patients regarding jaw restriction and retrognathia.

Study Design: Seven FOP patients were evaluated retrospectively in this observational study. Inclusion criteria were detection of ACVR1 gene mutation and complete craniofacial CT examination.
