Left egocentric neglect in early subacute right-stroke patients is related to damage of the superior longitudinal fasciculus.

A typical consequence of stroke in the right hemisphere is unilateral spatial neglect. Distinct forms of neglect have been described, such as space-based (egocentric) and object-based (allocentric) neglect. However, the relationship between these two forms of neglect is still far from being understood, as well as their neural substrates.

Women Stroke Association Statement on Stroke.

We describe the current and future objectives of the Women Stroke Association, a nonprofit multidisciplinary organization promoting research awareness on medical, psychological, and social issues concerning women affected by cerebrocardiovascular disease. In this paper, we deal with only cerebrovascular disease, whereas cardiovascular disorders will be addressed in a future paper. Gender differences in the clinical presentation of cerebrovascular diseases have been repeatedly suggested, and some treatment options may not be as effective and safe in men and women.

Cerebral transverse sinus morphology as detected by MR venography in patients with chronic migraine.

Objective: To clarify the frequency and characteristics of altered transverse sinus morphology in a series of consecutive patients with chronic migraine.

Background: As terminology, neuroradiological techniques and patient selection differ widely across various studies, reliable, reproducible information is lacking on the frequency of cerebral transverse sinus asymmetry as measured by cerebral magnetic resonance venography in patients with chronic migraine.

Methods: We assessed the frequency and characteristics of transverse sinus asymmetries and their correlation with the chronic migraine phenotype in a blind, cross-sectional magnetic resonance venographic study in a series of 83 consecutive patients with chronic migraine.

Anterior choroidal artery territory infarction.

The anterior choroidal artery (AChA) originates from the posterior wall of the internal carotid distal to the posterior communicating artery and proximal to the intracerebral carotid bifurcation. This thin artery is rarely the cause of aneurysm and only accounts for 2-5% of all aneurysms. Even though the AChA territory shows large variations among individuals, it supplies crucial motor and sensory structures, such as the internal capsule, optic tract, the posterior limb of the internal capsule, the cerebral peduncle, and the choroid plexus.

Contrast echocardiography and migraine in divers with patent foramen ovale.

Background: It has been proposed that the patent foramen ovale (PFO) may be associated with migraine, in particular migraine with aura. However, it is not clear whether paradoxical embolism triggers crises of headache. Cerebral embolization is provoked in subjects with PFO through contrast echocardiography, a safe method to diagnose the presence of foramen ovale pervium.

A case of primary breast lymphoma.

The case of a patient with a lesion in the right breast, is discussed. Retrospective evaluation of mammography and US previously performed elsewhere were not fully helpful in the differential diagnosis between benign and malignant and MRI was necessary. Morphological and dynamic characteristics could be indicative of an expansive/infiltrating lesion of the breast and support the staging.

Primary central nervous system lymphoma: role of DWI in the differential diagnosis.

The case of a female patient admitted to the hospital for a syncopal episode characterized by mental confusion, retrograde amnesia, agnosia, lack of sphincter control and behavior disorders, is presented. Cranial CT showed a frontal bihemispheric lesion. MRI completed with DWI was then performed to better define the nature of the lesion and for an in-depth diagnostic study.

Unusual lesion of the thalamic pineal region: role of conventional MRI and DWI in the differential diagnosis.

The case of a 53-year-old female patient admitted to the Emergency department with symptoms from right third cranial nerve of acute onset, is presented. Cranial CT, performed in emergency, documented an intra-axial mass which required an in-depth diagnostic study with cranial MRI after contrast administration. Conventional MRI and DWI helped in correct lesion characterization and in the differential diagnosis with other brain disorders.

Multiple watershed cerebral infarcts.

The case of a 63-year-old female patient affected by arterial hypertension under home therapy, with disordered consciousness and confusion, is discussed. At the emergency department of another hospital she underwent cranial CT which showed mild swelling of right cerebral hemisphere. Based on the clinical suspicion of herpes simplex encephalitis compatible with a first MRI examination of the brain, the patient was admitted to the department of infectious disease of the polyclinic to confirm the diagnosis and plan the therapeutic approach.

DWI and MR-spectroscopy in the differential diagnosis of focal brain lesions.

The case of a patient with a previous history of cerebral infarction, shown to be positive for a brain neoformation on control CT, is presented. Subsequent MRI for an in-depth diagnostic study was completed with DWI and MR spectroscopy to define the nature of the lesion. The differential diagnosis of the lesion is discussed.

Conventional MRI, DWI and MR-spectroscopy in the study of focal brain lesions.

A case of a patient with neurologic symptoms is reported. Baseline MRI findings were inconclusive to establish a definitive diagnosis. The worsened neurologic and neuroradiologic pattern directed towards a diagnosis of tumor.

Combined diagnostic and therapeutic imaging in the diagnosis of venous sinus thrombosis in postpartum patients.

The case of a woman on day four post partum with sensorimotor deficit of the right side and CT evidence of a left temporofrontal hemorrhagic lesion, is presented. Attending physicians requested cerebral angiography. To better evaluate the clinical justification of requested imaging procedure the patient medical history and performed CT examination were carefully revised.
