"Eye of tiger sign" mimic in an adolescent boy with mitochondrial membrane protein associated neurodegeneration (MPAN).
Neurodegeneration with brain iron accumulation (NBIA) refers to an inherited heterogeneous group of disorders pathologically characterized by focal brain iron deposition. Clinical phenotype, imaging findings and genotype are variable among the different types of this disorder. In this case report, we describe the imaging finding of an adolescent boy with mitochondrial membrane protein associate...
متن کاملBrain iron quantification by MRI in mitochondrial membrane protein-associated neurodegeneration under iron-chelating therapy
Therapeutic trials for Neurodegeneration with Brain Iron Accumulation have aimed at a reduction of cerebral iron content. A 13-year-old girl with mitochondrial membrane protein-associated neurodegeneration treated with an iron-chelating agent was monitored by R2 relaxometry, R2* relaxometry, and quantitative susceptibility mapping to estimate the brain iron content. The highly increased brain i...
متن کاملTranscranial sonography in movement disorders.
BACKGROUND Transcranial sonography (TCS) in the B-mode has the ability to image, infratentorial and supratentorial brain structures. For this reason, it has potential use in the diagnosis and differential diagnosis of various intracranial pathologies. METHODS AND RESULTS The authors reviewed the contribution of TCS to the differentiation of a number of neurodegenerative diseases: in parkinson...
متن کامل[Transcranial sonography in Parkinson's disease].
An abnormal hyperechogenecity of substantia nigra is thought to be the most characteristic sonographic feature in Parkinson's disease (PD). However specificity and sensitivity of the ultrasound method should be refined. Using transcranial sonography, authors have examined 168 patients with different clinical signs of parkinsonism, including 99 patients with idiopathic PD, and 56 patients withou...
متن کاملTranscranial Doppler sonography in fulminant hepatic failure.
UNLABELLED The clinical course of patients with fulminant hepatic failure (FHF) is often worsened by the presence of cerebral edema and endocranial hypertension. In spite of the multiple studies using Transcranial Doppler Sonography (TCDS), few have shown the cerebral blood flow (CBF) pattern among patients with encephalopathy resulting from FHF. OBJECTIVE Our objective was to characterize th...
