METHODS: Between March 1st, 2011, and January 30th, 2013, all admitted infants born before 29 weeks of gestation were eligible for Doppler imaging. Perfusion images were acquired in a standard coronal plane. Image quality was assessed by two authors (MR, PG). The region of interest (ROI) was manually selected. A segmentation tool was developed to separate color data from the greyscale 2D images, leading to a percentage and number of color pixels in the image (Doppler color index; DCI). Intra- and inter-observer agreement was analyzed. RESULTS: Intra- and inter-observer agreement for placement of ROIs was good (bias −0.24 resp. −0.74 percentage points). Color Doppler was able to depict microvessels in cortex, white matter and deep grey matter. The median DCI in a region of cortex-white matter was 7.8% with a wide range (1.4%–25.6%). There was no significant difference between the left and right hemisphere (Mann-Whitney U, P-value 0.61). Clinically relevant observations were tabulated, e.g. distant effect of germinal matrix hemorrhage (GMH) on regional perfusion. CONCLUSION: Sonographic small vessel visualisation may help understand pathogenetic mechanisms related to perfusion and is valuable to monitor effects of treatment.","PeriodicalId":89989,"journal":{"name":"Journal of pediatric neuroradiology","volume":"10 1","pages":"155 - 160"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91058281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was no history of associated fever or trauma. No bowel or bladder involvement was noted. On examination there was bilateral lower limb areflexia with little sensory involvement. The rest of the systemic examination was unremarkable. Cerebrospinal Fluid (CSF) examination revealed elevated protein level (800 mg/dl, normal range is 20–40 mg/dl) consistent with albumin cytological dissociation with nerve conduction study showing slow conduction consistent with demyelinating polyneuropathy. Based on clinical signs, symptoms and lab investigation diagnosis of Guillain Barre syndrome (GBS) was made and patient was put on intravenous immunoglobulin therapy. Before starting the treatment magnetic resonance imaging (MRI) spine was performed to rule out compressive myelopathy or myelitis. Pre contrast images were normal however post contrast images of spine revealed enhancement of cauda equina nerve roots and conus medullaris (Fig. 1) with preferential enhancement of ventral spinal nerve roots as compared to dorsal nerve roots (Fig. 2) GBS is an acute symmetrical inflammatory demyelinating polyneuropathy [1] that involves the peripheral nervous system.

The etiology and pathophysiology of childhood cerebral arteriopathies are not completely understood. The diagnosis is mainly based on clinical presentation and neuroimaging findings with considerable overlapping and discrepancy between diagnoses. We report the case of a young man who presented with an acute right basal ganglia infarct, and was found to have a focal cerebral arteriopathy of the intracranial right internal carotid artery that fluctuated clinically but resolved in four weeks with conservative management. The diagnoses of IAD and TCA were considered. We review and discuss the literature and the difficulties with the current terminology and classifications. In order to better understand the natural history and management there is a need to standardize the terminology and classifications of cerebral arteriopathies of the children and young adults.","PeriodicalId":89989,"journal":{"name":"Journal of pediatric neuroradiology","volume":"19 1","pages":"147 - 151"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86777688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We performed a retrospective study in children with the cingulate imaging sign with apparent diffusion coefficient (ADC) measurements in the anterior and posterior cingulate region, as well as in a reference region in the vitreous. There were 18 NF1 patients and 18 matched controls age 2–14 yr in whom ADC measurements were performed. We found significantly higher ADC values in NF1 patients in the visibly abnormal anterior cingulate, but also in the normal appearing posterior cingulate regions (p < 0.00001). Major considerations to explain the high ADC values include vasogenic edema and abnormal myelination. Given its location in the cingulate, our observed magnetic resonance imaging sign may bear relevance to cognitive symptoms in NF1 patients and warrants further investigation with correlating studies.","PeriodicalId":89989,"journal":{"name":"Journal of pediatric neuroradiology","volume":"17 1","pages":"121 - 126"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78300735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiologic appearance consists in cortical/subcortical posterior cerebral artery territory lesions.
