An alpha-streptococcus brain abscess was produced in five dogs and studied with magnetic resonance (MR) imaging (0.5 T) and computed tomography (CT). Non-contrastand contrast-enhanced CT scans were obtained using gadolinium diethylenetriaminepentaacetic acid (Gd DTPA) for MR imaging and meglumine iothalamate for CT scanning. Each animal was evaluated in the early and later cerebritis stages of ...

An undeformed metadolerite dyke cutting foliated pyroxene-granulite facies gneisses in the Jotunhelm, Norway, has almandine rods replacing the cores of plagioclase laths, although garnet is generally absent from the enclosing gneisses, and is not present in reaction zones between peridotites and gneisses. Chemical analyses of the dyke and its garnet, plagioclase, and clinopyroxene are given. Th...

This work focuses on the seismic response of a volcano to different magmatic processes with the aim of sheding light on their driving physics as tracked by seismicity. We study seismic time series recorded at basaltic volcanoes and identify generic seismicity patterns characteristic of (i) inter-eruptive, (ii) reservoir feeding, (iii) reservoir leak, and (iv) dyke injection phases of volcanic a...

Cornelius Gysbert Dyke, MD (Fig 1), is widely acknowledged as the first American radiologist to devote his full professional effort to the field of neuroradiology. A brilliant diagnostician, careful and thorough, he established respect for the contributions of the neuroradiologist with the neuroclinicians of his time. More than anyone else then or for a number of years thereafter, he set the st...

Dyke Davidoff Masson syndrome (DDMS) is characterized by seizures, facial asymmetry, contralateral hemiplegia and mental retardation. The characteristic radiologic features are cerebral hemiatrophy with homolateral hypertrophy of the skull and sinuses. We report a case of DDMS in an 18-month-old girl who presented with right sided focal seizures, hemiparesis of the same side, and delayed milest...

[1] Lava dome eruptions are commonly characterized by large fluctuations in discharge rate with cyclic behaviour on time-scales ranging from hours to decades. Examples include Bezymianny volcano (Russia), Merapi (Java), Santiaguito (Guatemala), Mt St Helens (USA), Mt Unzen (Japan), and Soufrière Hills volcano (Montserrat). Previous models have assumed simple cylindrical conduits for magma trans...

Refractory epilepsy is common in practice of neurology. Dyke-Davidoff-Masson Syndrome (DDMS) is one among the syndromes associated with refractory epilepsy. We have come across a case of Dyke-Davidoff-Masson syndrome while investigating a case of refractory epilepsy. When cerebral hemi atrophy is associated with the radiological features of osseous hypertrophy of calvarium, hyper-pneumatisation...

Dyke-Davidoff-Masson syndrome refers to atrophy of one cerebral hemisphere (hemiatrophy) due to an insult to the brain in fetal or early childhood period. This is an uncommon condition. We present a case of a nine month- old female presented with seizure and weakness of the right upper and lower extremities and subsequently computed tomography was performed and showed hemiatrophy of the left fr...
