A 39-year-old woman presented with a rare case of "kissing" brainstem cavernomas formed by separate lesions enlarging with simultaneous recurrent hemorrhages, which was successfully treated by staged resection using a trans-fourth ventricular floor approach. She had a familial history of cerebral cavernous angioma, and presented with a history of four episodes of sudden neurological deteriorati...

Millard-Gubler Syndrome is a rare neurological condition caused by damage to the sixth and seventh cranial nerves, as well corticospinal tract in brainstem. It characterized presence of ipsilateral facial paralysis contralateral hemiplegia. We report 55-year-old male patient who presented with sudden onset left-sided weakness. Imaging revealed pontine infarct. The therefore, was diagnosed also ...

BACKGROUND The anterior corticospinal tract (CST) has been suggested as one of the ipsilateral motor pathways, which contribute to motor recovery following stroke. In this study, we report on a patient who showed deterioration of pre-existing hemiparesis due to an injury of the ipsilateral anterior CST following a pontine infarct, as evaluated by diffusion tensor tractography (DTT). CASE PRES...

BACKGROUND AND PURPOSE The purpose of this research was to investigate the impact of lesion location on motor excitability and motor performance. METHODS We studied patients with pure motor strokes in 4 different brain areas: motor cortex lesions (n=7), striatocapsular lesions (n=13), lacunar lesions of the internal capsule (n=13), and paramedian pontine lesions (n=10). Motor performance test...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013203447 DESCRIPTION Though uncommon, bilateral middle cerebellar peduncle (MCP) hyperintensities have been reported following pontine infarcts, in Wilson disease (WD) and due to other aetiologies. In WD, the ‘face of the giant panda’ sign, internal capsule hyperinten...

In the primary somatosensory cortex (SI), the body surface is mapped in a relatively continuous fashion, with adjacent body regions represented in adjacent cortical domains. In contrast, somatosensory maps found in regions of the cerebellar hemispheres, which are influenced by the SI through a monosynaptic link in the pontine nuclei, are discontinuous ("fractured") in organization. To elucidate...

BACKGROUND AND PURPOSE This study investigated whether the topography of hypertensive pontine microhemorrhages (hPMHs) resembles that of larger primary pontine hemorrhages. METHODS Sixty-nine consecutive patients with small-vessel disease underwent imaging with gradient-echo MRI, and 27 patients with hPMH were detected. Lesion size and location along the rostrocaudal (longitudinal), lateral (...

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a newly named condition of pontine-centric inflammatory disorder. 1) The cardinal feature of the disease is punctate gadolinium enhancement " peppering " the pons on magnetic resonance imaging (MRI). The unique MRI features

We present the first case of central pontine myelinolysis (CPM) confirmed by high resolution computerized tomography (CT) in which auditory brainstem responses (ABR) revealed impaired conduction beyond the mid pons. The combined use of CT and ABR in the diagnosis of central pontine myelinolysis is discussed.

Two cases of pontine infarct with Wallerian degeneration (WD) of the pontocerebellar fibers are described. WD of pontocerebellar fibers, seen bilaterally along the transverse pontine fibers, is more visible in the middle cerebellar peduncles and extends into the white matter of the cerebellar hemispheres. Understanding the anatomy of the white matter and the temporal evolution of this degenerat...
