Takotsubo cardiomyopathy features at cardiac magnetic resonance

2012

Abstract Diagnosis of Takotsubo cardiomyopathy is based on clinical symptoms, electrocardiographic changes, absence of angiographic significant coronary lesions and presence of suggestive wall motion abnormalities. CardioMRI is an useful complementary tool especially to role out the diagnosis of myocarditis and of myocardial infarction with angiographically normal coronary artery and to document complications of the disease.

Therapeutic considerations in cerebellopontine angle lipomas inducing hemifacial spasm.

2000

Lipoma is a very rare tumour at the cerebellopontine angle. We report a case of incomplete hemifacial spasm, associated with a lipoma involving and compressing both facial and acoustic nerves at their origin in the brainstem. The patient was treated with medical therapy (botulinum toxin A) and surgery. We present a review of the last ten years of the literature, with particular regard to management.

Transcranial magnetic resonance-guided focused ultrasound thalamotomy as a safe treatment option in multiple sclerosis patients with essential tremor

2020

Transcranial magnetic resonance-guided focused ultrasound is a recently introduced incisionless treating option for essential tremor and tremor-dominant idiopathic Parkinson disease. There is preliminary evidence that it may result in a promising effective treatment option for other movement disorders too. Here, we report on two patients with multiple sclerosis with medication refractory debilitating essential tremor comorbidity who successfully underwent unilateral Vim tcMRgFUS thalamotomy for tremor control. Patients' clinical condition and expanded disability status scale scores showed no changes during the 1-year follow-up period with no evidence of multiple sclerosis activity or progre…

Treatment of multiple sclerosis with interferon beta in clinical practice: 2-year follow-up data from the South Italy Mobile MRI Project.

2006

This follow-up study assessed the 2-year clinical and magnetic resonance imaging (MRI) outcomes of patients with multiple sclerosis (MS) originally enrolled in an MRI study conducted at eight centres in south Italy (the South Italy Mobile MRI Project). Of the 597 MS patients recruited at baseline, 391 returned for the follow-up study. Of these, 363 provided 2-year clinical and MRI follow-up data, and 215 were still undergoing treatment with one of four interferon beta regimens: Avonex, 30 mcg intramuscularly once weekly; Betaferon, 250 mcg subcutaneously (sc) every other day; Rebif 22 mcg sc three times weekly (tiw; Rebif 22); or Rebif 44 mcg sc tiw (Rebif 44). Over the 2-year follow-up per…

Stellenwert von Computertomographie und Magnetresonanztomographie in der psychiatrischen Diagnostik

1997

This paper evaluates the role of computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis of psychiatric disorders according to the "International Classification of Diseases" (ICD-10). Indications for CT/MRI can be derived from ICD-10 for the identification or exclusion of defined cerebral lesions resp. for the etiology in organic disorders. Due to the lack of specific morphological findings, CT/MRI do not contribute to the classification of all other diagnoses. CT/ MRI can only exclude causal organic factors. However, ICD-10 provides only few guidelines for ruling out cerebral pathology (e.g. tumors in bulimic anorexia). Therefore, recommendations for routine CT/MRI-i…

Preoperative imaging of hilar cholangiocarcinoma: surgical evaluation of standard practises.

2004

UNLABELLED It was the goal of this study to compare the results of the preoperative diagnostic workup (ERC, MRC, and PTC) with the tumor extent of the surgical specimen in patients with hilar cholangiocarcinoma (hilCC). PATIENTS AND METHODS Between 9/97 and 12/2002 82 patients with hilCC were treated at our institution. In 59 patients tumor resection was feasible. Preoperative ERC, MRC and PTC - blinded for the idendity of the patients - were analysed retrospectively and compared with the surgical specimen. RESULTS PTC resulted in significantly superior visualization of the bile ducts including the hilar lesion compared to ERC and MRC (p < 0.01). ERC, MRC and PTC were correct in predicting …

Disconnected pancreatic duct syndrome: complete pancreas transection secondary to acute pancreatitis

2016

Disconnected pancreatic duct syndrome is a serious complication of acute pancreatitis which is defined by a complete discontinuity of the pancreatic duct, such that a viable side of the pancreas remains isolated from the gastrointestinal tract. This pancreatic disruption is infrequently observed in the clinical practice and its diagnostic and therapeutic management are controversial. We present an extreme case of disconnected pancreatic duct syndrome with complete duct disruption and pancreatic transection following acute pancreatitis, as well as the diagnostic and therapeutic processes carried out.

Restoring Neurological Physiology: The Innovative Role of High-Energy MR-Guided Focused Ultrasound (HIMRgFUS). Preliminary Data from a New Method of …

2017

Background Tremor is a disabling condition, common to several neurodegenerative diseases. Lesioning procedures and deep brain stimulation, respectively, of the ventralis intermedius nucleus for intentional tremor, and of the subthalamic nucleus for parkinsonian resting tremor, have been introduced in clinical practice for patients refractory to medical treatment. The combination of high-energy focused ultra-sound (HIFUS) with sophisticated magnetic resonance (MR) instrumentation, together with accurate knowledge of the stereotactic brain coordinates, represents a revolution in neuromodulation. Methods At the Neurosurgical Clinic and the Radiology Department of the University of Palermo,, tw…

Neuroanatomical changes in early Parkinson’s disease with mild cognitive impairment: a VBM study; the Parkinson’s Disease Cognitive Impairment Study …

2021

Introduction: Mild cognitive impairment (MCI) is common in Parkinson’s disease (PD), but the underlying pathological mechanism has not been fully understood. Voxel-based morphometry could be used to evaluate regional atrophy and its relationship with cognitive performances in early PD-MCI. Patients and Methods: One hundred and six patients with PD were recruited from a larger cohort of patients, the Parkinson’s Disease Cognitive Impairment Study (PaCoS). Subject underwent a T1-3D MRI and a complete clinical and neuropsychological evaluation. Patients were divided into PD with normal cognition (PD-NC) and PD-MCI according to the MDS level II criteria–modified for PD-MCI. A subgroup of early …
