The authors present their US findings in 24 patients with proved complicated midgut malrotation: volvulus in 18 and occlusive Ladd's bands in 6. All the 24 patients have had US examination prior to surgery. Contrast examinations were performed in only 9 patients, always after US and before surgery. The sonographic "whirlpool" pattern of the superior mesenteric vein and mesentery around the superior mesenteric artery was detected in 15 of the 18 patients with midgut volvulus, and was best seen using Doppler color. Embryological signification of midgut malrotation is discussed.
The occurrence of liver tumours in the course of Fanconi anaemia (FA) has been well documented. We present a case, review the literature and conclude that androgen therapy would increase the risk of developing tumours, most of which appear to be benign (adenomas or peliosis) and androgen-dependent, generally decreasing in size after cessation of treatment. Survival of patients is poor, mostly because of the rapid evolution of the tumour. In the absence of an allogenic bone marrow transplantation, administration of haematopoietic growth factors might be effective. As a preventive measure, other types of unsubstituted androgens may be used.
This focal sonographic periventricular pattern associated with mild ventriculomegaly without any abnormalities of the cerebral and cerebellar organogenesis nor cephalic biometry alteration in the third trimester of pregnancy should be considered as a marker of encephalitis following CMV infection of the foetal brain.
A case of neonatal manifestation of giant hypothalamic hamartoma is reported. It is suggested that hypothalamic hamartoma should be included in the list of neonatal intracerebral tumors. Magnetic resonance imaging appearance similar to that of normal gray matter on T1-weighted images and slightly hyperintense on T2-weighted images, without enhancement after gadolinium injection, is suggestive of the diagnosis. Hypothalamic hamartomas are congenital malformations, consisting of disorganized mature neuronal elements in proportions similar to that of normal tissue [1]. They are clinically evidenced in infants ranging from 1 to 7 years of age [1-5]. This report describes a histologically proved giant hypothalamic hamartoma diagnosed in the neonatal period. Magnetic resonance imaging (MRI) is helpful to distinguish this congenital non-evolutive malformation from more aggressive neonatal tumors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
