Background: Cerebral microbleeds (CMBs) are small round/oval lesions seen in MRI-specific sequences. They are divided in deep and lobar according to their location. Lobar CMBs (L-CMBs) are commonly associated with amyloid angiopathy. Although CMBs have been considered clinically silent for a long time, a growing body of evidence has shown that the...

The purpose of this retrospective study is to evaluate the prevalence and the imaging features of incidental intracranial aneurysms (IAs) in oncologic patients. We retrospectively examined 6599 brain CT studies performed for cancer staging (without and with intravenous iodinated contrast medium) at our institution, between January 2016 and December...

Background Since the pioneering reports of the so-called “leonine face” in cluster headache (CH) patients, cranial and facial features of these patients have been poorly investigated with conflicting results. We aimed to investigate whether abnormalities in craniometric measurements could characterize male CH patients and represent reliable and rep...

Thoracic paravertebral masses are a diagnostic challenge due to the broad spectrum of lesions that may be found in this compartment. The correct radiological approach is essential to narrow the differential diagnoses but, due to the overlap of imaging features of certain lesions, in selected cases, a pathological study may be necessary

IntroductionThe O’Donnell–Luria–Rodan (ODLURO) syndrome, caused by heterozygous mutation in the lysine N-methyltransferase2E (KMT2E) gene in chromosome 7q22, has been recently described. Mutation of KMT2E produces a protein-truncating variant gene that may be responsible for both developmental delay and intellectual disability disorders commonly de...

Dilated Virchow–Robin spaces (VRSs) are expansions of the normal perivascular spaces with a short axis greater than 2 mm or, according to some authors, greater than 3 mm. They are usually documented at the basal ganglia, at the convexity white matter (WM) and centrum semiovale, and at the mesencephalon. The anterior temporal WM is a recently descri...

Intramedullary spinal cord metastases are rarely encountered in patients suffering from extra - central nervous system primary cancer, with only 2 described cases reported in the literature deriving from esophageal cancer. Intramedullary spinal cord metastases may occur at any level of the spinal cord but cervical location is the most frequent. We...

Diamond-Blackfan anemia (DBA) is a rare congenital erythroid aplasia with a highly heterogeneous genetic background; it usually occurs in infancy. Approximately 30–40% of patients have other associated congenital anomalies; in particular, facial anomalies, such as cleft palate, are part of about 10% of the DBA clinical presentations. Pierre Robin s...

Background: Tumefactive multiple sclerosis (MS) is an unusual variant of demyelinating disease characterized by lesions with pseudotumoral appearance on radiological imaging mimicking other space-occupying lesions, such as neoplasms, infections, and infarction. Especially when the patient's medical history is incompatible with MS, the differential...

Understanding mechanisms for vessel tone regulation within the trigeminal nuclei is of great interest because some headache syndromes are due to dysregulation of such mechanisms. Previous experiments on animal models suggest that mastication may alter neuron metabolism and blood supply in these nuclei. To investigate this hypothesis in humans, arte...

This study aimed to verify whether brain abnormalities, previously described in patients with myotonic dystrophy type 1 (DM1) by magnetic resonance imaging (MRI), progressed over time and, if so, to characterize their progression. Thirteen DM1 patients, who had at least two MRI examinations, were retrospectively evaluated and included in the study....

Osteomas of the external auditory canal tend to be rather common; those of the internal auditory canal (IAC) are much rarer, though, with less than twenty cases reported in literature up to this very day. Bilateral IAC osteomas, as in this case, are extremely unusual.These benign bone tumors grow very slowly and this implies that the patient is ver...

Several studies demonstrated the involvement of GABA and reactive oxygen species (ROS) in trigeminal pain transmission; anyway, there are still poorly understood mechanisms modulating pain, resulting, for instance, in hypoalgesia in hypertensive patients. One possibility is that the activity of afferent neurons during mastication modulates ROS prod...

To investigate the functional response of neural pathways associated with vestibular stimulation in patients with vestibular migraine (VM). Twelve patients with VM underwent whole-brain blood oxygen level-dependent (BOLD) fMRI during ear irrigation with cold water. The functional response of neural pathways to this stimulation in patients with VM w...

Neurofibromatosis type 1 (NF1) is a relatively common single-gene disorder, and is caused by heterozygous mutations in the NF1 gene that result in a loss of activity or in a nonfunctional neurofibromin protein. Despite the common association of NF1 with neurocutaneous features, its pathology can extend to numerous tissues not derived from the neura...

The discrimination between recurrent glioma and radiation injury is often a challenge on conventional magnetic resonance imaging (MRI). We verified whether adding and combining proton MR spectroscopic imaging ((1)H-MRSI), diffusion-weighted imaging (DWI) and perfusion-weighted imaging (PWI) information at 3 Tesla facilitate such discrimination. Twe...

The aim of this study was to assess differences in the presence, size, number and site of dilated cerebral Virchow-Robin spaces (VRSd) between patients with multiple sclerosis (MS) in the inactive phase and healthy controls, and between MS patients with disabling (MSd) or nondisabling (MSnd) disease. The study was performed by retrospectively analy...

In this article, we review the expected course of each of the 12 cranial nerves. Traditional magnetic resonance imaging depicts only the larger cranial nerves but SSFP sequences of magnetic resonance imaging are capable of depicting the cisternal segments of 12 cranial nerves and also provide submillimetric spatial resolution.

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 mai...

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 t...
