SummaryDescribed herein is a case of distended abdomen in a 4-year-old boy with a ventriculoperitoneal (VP) shunt due to bilateral intraventricular hemorrhage following premature birth. Physical examination and laboratory tests revealed tenderness in the lower quadrants, with mild leukocytosis and normal C‑reactive protein levels. X‑ray demonstrated an intact VP shunt catheter but cranial displacement of the large intestine. Ultrasonography confirmed a large pseudocyst around the VP shunt, with extension from the symphysis to the sternum. The distal part of the VP shunt was surgically revised and 2.5 l of cerebrospinal fluid were evacuated. The boy made a full clinical recovery. Conventional X‑rays, routinely used to confirm or exclude VP shunt continuity, may provide important clues regarding to the etiology of VP shunt dysfunction.

Background: Neovascularization is one of the most important risk factors for unstable plaque. This study was designed to correlate plaque thickness, artery stenosis and levels of serum C-reactive protein with the degree of intraplaque enhancement determined by contrast-enhanced ultrasound. Patients and methods: Contrast-enhanced ultrasound was performed on 72 carotid atherosclerotic plaques in 48 patients. Contrast enhancement within the plaque was categorized as grade 1, 2 or 3. Maximum plaque thickness was measured in short-axis view. Carotid artery stenosis was categorized as mild, moderate or severe. Results: Plaque contrast enhancement was not associated with the degree of artery stenosis or with plaque thickness. Serum C-reactive protein levels were positively correlated with the number of new vessels in the plaque. C-reactive protein levels increased in the three groups(Grade 1: 3.72±1.79mg/L; Grade 2: 7.88±4.24 mg/L; Grade 3: 11.02±3.52 mg/L), with significant differences among them (F=10.14, P<0.01), and significant differences between each two groups (P<0.05). Spearman’s rank correlation analysis showed that serum C-reactive protein levels were positively correlated with the degree of carotid plaque enhancement (Rs =0.69, P<0.01). Conclusions: The combination of C-reactive protein levels and intraplaque neovascularization detected by contrast-enhanced ultrasound may allow more accurate evaluation of plaque stability.
