Does Phase-Contrast Imaging through the Cerebral Aqueduct Predict the Outcome of Lumbar CSF Drainage or Shunt Surgery in Patients with Suspected Adult Hydrocephalus? ADULT BRAIN
CONCLUSIONS: This study suggests that the results of phase-contrast MR imaging through the cerebral aqueduct alone should not be used to select patients for diagnostic or therapeutic CSF diversion.

Letter to the Editor: Pneumocephalus: Is the needle size significant?
Discussion. Pneumocephalus is defined by two mechanisms: a ball-valve and an inverted bottle concept.1 The ball-valve type implies positive pressure events, such as coughing or valsalva maneuvers, that prevent air escape. Tension pneumocephalus is included in this mechanism, causing a parenchymal mass effect. The inverted bottle theory includes a negative intracranial pressure gradient following cerebrospinal fluid drainage, relieved by air influx. A small pneumocephalus is usually sealed by blood clots or granulation, allowing spontaneous reabsorption and resolution.[1] Otherwise, the lateral positioning of a patient duri...

Correlation of CSF flow using phase-contrast MRI with ventriculomegaly and CSF opening pressure in mucopolysaccharidoses
ConclusionsIn MPS patients ventriculomegaly is associated with a severe phenotype, increased cognitive decline, WM lesion severity and enlarged PVS. The authors have shown that there are associations between CSF flow measurements and measurements related to CSF volumetrics. There was also an association of volumetric measurements with the degree of dilated PVS.

E-075 neurosarcoidosis presenting as aneurysmal subarachnoid hemorrhage: an interesting case and novel treatment
Neurosarcoidosis, the term used for sarcoidosis involving the central nervous system, represents an uncommon form of sarcoidosis, found in a 5% of patients with systemic sarcoidosis. Clinically evident cerebrovascular involvement in neurosarcoidosis has been reported but appears to be an extremely rare manifestation of neurosarcoidosis. The literature describes these cerebral vasculopathic changes as areas of stenosis and/or vascular irregularity, with clinical manifestations including headache, ischemic stroke, and parenchymal hemorrhage. Neurosarcoidosis has even been described as the etiology for a case of moyamoya synd...

What Causes Ataxia?
Discussion Coordination and balance problems are caused by various problems affecting the central and peripheral nervous system. Normal development of a child or weakness of a child are commonly mistaken for true ataxia. Ataxia specifically refers to “…impairment of the coordination of movement without loss of muscle strength.” If it is purely due to abnormalities of the cerebellum then there should be no changes in mental status, sensation or weakness. Sometimes it is difficult to determine if there are abnormalities in other areas. For example, Guillian-Barre often presents with difficulty or clumsy wal...
