The value of serial MR imaging in the assessment of brain metastases volume control during stereotactic radiosurgery
Purpose: To evaluate early tumour control capabilities of Stereotactic Radiosurgery (SRS) in the treatment of brain metastasis and the role of follow-up MR imaging. Methods and Materials: MR imaging of 54 metastases in 31 patients treated with SRS who underwent follow-up MR imaging within 12 months were retrospectively reviewed. Tumours were characterized as either enlarged (>20% volume increase), stable (follow-up volume ±20% of the initial volume), or decreased (> 0% volume decrease). Results: Within the first 6 weeks following SRS a decrease was observed in 25 (52%) of the tumours in the extent of 63% in size. Tumour reduction varied according to histopathological subtype with 38% of non…
MR imaging of the brain: findings in asymptomatic patients with thalassemia intermedia and sickle cell-thalassemia disease.
The purpose of this study was to evaluate the spectrum of MR findings of the brain in asymptomatic patients affected with thalassemia intermedia or sickle cell-thalassemia disease to prevent brain damage by identifying patients at risk for stroke so that transfusional or pharmacologic treatment could be implemented.Forty-one asymptomatic patients who were younger than 50 years and were affected by minor hemoglobinopathies underwent MR imaging of the brain. Ischemic lesions were classified as small, medium, or large and as single or multifocal. Atrophic changes were graded subjectively as mild, moderate, or severe. A grade of brain damage was assigned to every patient. The frequency and seve…
HIPPOCAMPAL REVERSIBLE LESIONS IN A CASE OF TRANSIENT GLOBAL AMNESIA
PURPOSE: We present a case of transient global amnesia (TGA) onset in a 52-year-old male with a medical history of migraine. METHODS: Patient was taken to ER by his colleagues which reported that after an emotional stress he suddenly appeared perplexed and started asking repetitive questions. In ER a neurological examination excluded other neurological signs or symptoms and it was confirmed that cognitive impairment was limited to the amnesia domain; electroencephalography was unremarkable and he had no history of epileptic seizures or head trauma. At the neurologic examination Capland and Hodges criteria were fulfilled and the diagnostic hypothesis of TGA was placed. He underwent to a brai…
PECULIARE EVOLUZIONE DELLA SEMEIOTICA NEURORADIOLOGICA DI UN CASO DI MALATTIA DEMIELINIZZANTE CON LESIONI PSEUDOTUMORALI
SCOPO DEL LAVORO Presentiamo un caso di una paziente di 24 anni che giunge alla nostra attenzione per la comparsa di disartria come quadro clinico d’esordio di una forma aggressiva di malattia demielinizzante di cui si valuta l’atipica evoluzione neuroradiologica delle lesioni pseudotumorali che la caratterizzano e le possibili diagnosi differenziali. MATERIALI E METODI La paziente dopo una prima valutazione in PS è stata sottoposta a TC encefalo, ricoverata presso l’U.O. di Neurologia, sottoposta a controlli RM seriati (anche con tecniche avanzate); durante la degenza è stata inoltre effettuata una biopsia stereotassica. RISULTATI La TC ha rilevato almeno tre lesioni ipodense: a sinistra…
A CASE OF JUVENILE STROKE CAUSED BY ACTINIC CERVICAL ARTERIOPATHY
Introduction: Radiation Arteriopathy is a vascular disease characterized by progressive arterial stenosis that may occur after external radiotherapy (RT) directed to a specific body region affected by malignant tumours. The arterial damage usually starts many years after the injury and the specific pathogenesis is unknown, though atherosclerosis praecox, endothelial damage, adventitial fibrosis and vasa vasorum obliteration are likely involved mechanisms. In patients with previously irradiated neck or head cancers, supra aortic arteries can be affected in their segments exposed to radiations leading to a gradual lumen narrowing. This late complication leads to a progressive stenosis of extr…
