Incidental Detection of a Rare Pediatric High-Grade Fibrosarcoma in a Post-traumatic Setting: The Conundrum of Intra-Abdominal Hematoma versus Neoplasia.

Infantile fibrosarcoma (IF) is a rare malignant fibroblastic tumor that affects infants and young children, occurring most commonly in the extremities. Here, we present a 14-year-old patient with an abdominal mass incidentally detected after a blunt injury to the abdomen. The initial trauma protocol CT revealed a high attenuation mesenteric lesion in the left central abdomen suggestive of mesenteric hematoma.

A Combined Region- and Pixel-Based Deep Learning Approach for Quantifying Abdominal Adipose Tissue in Adolescents Using Dixon Magnetic Resonance Imaging.

Background: The development of adipose tissue during adolescence may provide valuable insights into obesity-associated diseases. We propose an automated convolutional neural network (CNN) approach using Dixon-based magnetic resonance imaging (MRI) to quantity abdominal subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) in children and adolescents.

Methods: 474 abdominal Dixon MRI scans of 136 young healthy volunteers (aged 8-18) were included in this study.

Splenic Size and Volume Measurements in Patients with Chronic Lymphocytic Leukemia.

Rationale And Objectives: To determine which methods of assessment of splenic size most accurately represent the actual spleen volume in patients with Chronic Lymphocytic Leukemia (CLL).

Materials And Methods: The Abdominal Computed Tomography images of 48 patients with CLL enrolled on a phase 2 clinical trial at two time-points before and after 2-months of continuous acalabrutinib treatment were analyzed. Linear one-dimensional measurements of the spleen were taken in different planes.

MRI evaluation of diffuse subcutaneous neurofibroma of the lower limb in a low resource setting.

An unusual type of neurofibroma predominantly seen in children and young adults is diffuse neurofibroma. We present a 25-year-old female with recurring soft tissue masses in her right lower limb. MRI showed areas of iso-intensity and hyperintensity relative to skeletal muscle within the subcutaneous fat.
