<b>We present a radiologic case of a teenager with portal, inferior mesenteric, superior mesenteric, and splenic vein thromboses presenting with acute abdominal pain and treated conservatively with anticoagulation therapy. Ultrasound and computed tomography were done at the acute presentation and follow up magnetic resonance images were performed. One year of anticoagulation therapy correlated with almost complete resolution of splanchnic thrombosis; however, the superior mesenteric vein continues to remain severely dilated close to the confluence on subsequent annual imaging. The initial imaging also diagnosed multiple phlebolith in the pelvis. We suspect this is a congenital malformation of the porto-splanchnic circulation presenting with acute thrombosis. Differential is variceal dilatation as sequela of extensive thrombosis.</b> Read More

Leptomeningeal dissemination (LD) is a common occurrence in primary central nervous system tumours. The most common tumours that develop LD are medulloblastoma, germ cell tumours, and glial tumours. However, in gliomas, this occurrence is rare. It has been reported that only 2-5% of children with low-grade gliomas present with LD. Retrospective review of the Pediatric Brain Tumour Study Group database revealed 4 cases of gliomas with leptomeningeal enhancement at initial presentation: 2 cases of pilocytic astrocytoma, 1 case of glioblastoma multiform in the cervical spinal cord and 1 case of diffuse intrinsic pontine glioma. The presence of LD at initial presentation of gliomas usually indicates poor prognosis, even in cases of pilocytic astrocytoma. Therapeutics also become a chalenge in face of such a rare and diffuse finding. Differential diagnosis should be made imaging wise with possible infectious/inflammatory process giving LD and focal lesions simulating tumors. Identification of LD at initial diagnosis is of major importance for treatment options and prognostication of gliomas in children. Read More

Pediatric carotid artery Intima-Media Thickness (IMT) is a non-invasive ultrasound marker of early atherosclerosis. Obesity in children is associated with increased IMT. The objective of this meta-analysis is to report IMT values in children living with overweight/obesity in the literature. Read More
