    A child with neurofibromatosis type 1 (NF1) with headache was submitted to magnetic resonanace imaging and a pseudovasculitic lesion was found. Vascular lesions are uncommon in patients with NF1 and our case highlights an even more rare feature of this form of vascular disease.

    White matter changes are one of the several aging brain alterations. Actually, magnetic resonance imaging is the best diagnostic tool in investigation and monitoring these lesions that determine some common clinical manifestations in the elderly population.

    Migraine is one of the most common forms of primary headache. In recent years there have been important discoveries thanks to a greater understanding of conventional radiologic studies and the advent of the advanced exams. This has led to a revolution of the knowledge of its pathophysiological mechanisms and opens the way for future therapeutic developments.

    Neurodegenerative disorders are an inhomogeneous group of neurological diseases that affect a large part of the population because of the rise in life expectancy. Although clinical manifestations are important to make the correct diagnosis, the new advanced imaging technique represent a very useful tool for the diagnostic work-up.

  • Rhythm-specific modulation of the sensorimotor network in drug-naive patients with Parkinson's disease by levodopa.

    Brain activity during rest is characterized by slow (0.01-0.1 Hz) fluctuations of blood oxygenation level-dependent functional magnetic resonance imaging signals. These fluctuations are organized as functional connectivity networks called resting-state networks, anatomically corresponding to specific neuronal circuits. As Parkinson's disease is mainly characterized by a dysfunction of the sensorimotor pathways, which can be influenced by levodopa administration, the present study investigated the functional connectivity changes within the sensorimotor resting-state network in drug-naïve patients with Parkinson's disease after acute levodopa administration. Using a double-blind placebo-controlled design, resting-state functional magnetic resonance imaging was carried out in 20 drug-naïve patients with Parkinson's disease, immediately before and 60 min after, oral administration of either levodopa or placebo. Control resting-state functional magnetic resonance imaging data were recorded in 18 age- and sex-matched healthy volunteers. Independent component analysis was performed to extract resting-state network maps and associated time-course spectral features. At the anatomical level, levodopa enhanced the sensorimotor network functional connectivity in the supplementary motor area, a region where drug-naïve patients with Parkinson's disease exhibited reduced signal fluctuations compared with untreated patients. At the spectral frequency level, levodopa stimulated these fluctuations in a selective frequency band of the sensorimotor network. The reported effects induced by levodopa on sensorimotor network topological and spectral features confirm that the sensorimotor system is a target of acute levodopa administration in drug-naïve patients with Parkinson's disease. Moreover, while the regional changes in supplementary motor area reflect the functional improvement in motor function, the rhythm-specific modulation induced by the dopamine precursor discloses a novel aspect of pharmacological stimulation in Parkinson's disease, adding further insight to the comprehension of levodopa action.

  • Trigeminal neuralgia and persistent trigeminal artery.

    We report a case of trigeminal neuralgia caused by persistent trigeminal artery (PTA) associated with asymptomatic left temporal cavernoma. Our patient presented unstable blood hypertension and the pain of typical trigeminal neuralgia over the second and third divisions of the nerve in the right side of the face. The attacks were often precipitated during physical exertion. MRI and Angio-MRI revealed the persistent carotid basilar anastomosis and occasionally left parietal cavernoma. After drug treatment of blood hypertension, spontaneous recovery of neuralgia was observed and we planned surgical treatment of left temporal cavernoma.

    Converging neuropsychological evidence suggests that in migraine executive functions (EF) may be affected during interictal periods.

  • Paget's Disease. A Case Report.

    Paget's disease (PD) is a common focal progressive osteometabolic disorder characterised by a disturbance in bone modelling and remodelling, because of an increase in osteoblastic and osteoclastic activity. It is a condition of unknown aetiology affecting approximately 3% of the population over 40 years of age and, approximately 10% of those over the age of 85 years. It is most common in Northern Europe and Australia and is rare in Asia and Africa. We describe the case of a 71-year-old man diagnosed with PD confined to the sacrum. After laboratory test, an imaging study with radiography, scintigraphy, computed tomography (CT) and magnetic resonance imaging (MRI) was performed disclosing findings compatible with Paget's disease in middle pathologic phase. The diagnosis was confirmed at biopsy. The structural modification of the sacrum with spongiosa rarefaction, thickening of bone and intact bone cortical, confirmed by CT, are tipical of an intermediate phase of PD. This was also supported by signal MRI changes showing substitution of the red by the fat medulla, visualized by FS sequences. Once the treatment for the bone disease was established, the patient no longer complained of pain. Special attention should be paid to male and elderly patients with pain in the lumbar spine because of the potential risk cancer development (21). The radiologist must be attentive to the possible presentations and complications of PD, even in uncommon sites, trying whenever possible to correlate the radiological features with the patient's clinical symptoms.

  • Giant dilatations of virchow-robin spaces in the midbrain. MRI aspects and review of the literature.

    Virchow-Robin spaces are lesions often seen in the brain parenchyma but their etiopathogenesis remains unsettled. Giant Virchow-Robin spaces placed in the midbrain are extremely rare. We describe three patients with a diagnosis of giant Virchow-Robin spaces in the midbrain, and their clinical and radiologic findings. We reviewed the literature in terms of the etiopathology, anatomic and radiologic appearance and differential diagnosis of the giant Virchow-Robin spaces. The diagno-stic role of the high Tesla magnetic resonance devices and new sequences techniques such as three dimensional isotropic acquisition and diffusion tensor imaging were also evaluated in this case series.

  • Pain processing in patients with migraine: an event-related fMRI study during trigeminal nociceptive stimulation.

    We explored the functional pattern of the pain-processing network in patients with migraine, in the interictal periods, during trigeminal noxious stimulation. Contact heat evoked potential stimulation induced thermal pain and functional magnetic resonance imaging were used to measure whole-brain activation in 16 patients with episodic migraine without aura and 16 age- and gender-matched healthy controls in response to a severe (53°C) noxious, a moderate (51°C) noxious, and a control (41°C) stimulus applied to the maxillary skin. When comparing the fMRI activation over the entire brain, patients with migraine, with respect to healthy controls, showed a significantly greater activation in the perigenual part of anterior cingulate cortex at 51°C and less activation in the bilateral secondary somatosensory cortex at 53°C. A group-by-stimulus interaction analysis revealed a region in the pons showing a divergent response in patients and healthy controls. Correlation analyses demonstrated that the pons activation correlated with higher headache-related disability in patients. Our findings demonstrate increased antinociceptive activity in patients with migraine, which may represent a compensatory reorganization to modulate pain perception at the same intensity of healthy controls.
