Histiocytic necrotizing lymphadenitis, also known as Kikuchi-Fujimoto disease, is a benign, self-limited disorder, associated with B symptoms (fever, weight loss) and painful lymphadenopathy. The combination of lymphadenopathy with B symptoms in the pediatric population raises suspicion for malignant diseases such as lymphoma, neuroblastoma, and rhabdomyosarcoma. We evaluated a series of children with biopsy-proven histiocytic necrotizing lymphadenitis to assess for unique imaging characteristics. Read More

Background: Vitamin C deficiency remains an underrecognized cause of musculoskeletal symptoms in children with suboptimal nutrition. Vitamin C plays major roles in collagen, nitric oxide, and norepinephrine formation, and is essential from the diet because humans cannot synthesize it. In children with scurvy, musculoskeletal symptoms such as limp or refusal to bear weight, occur in approximately 80% of patients. Early recognition can prevent invasive, costly workups and limit morbidity. Objective: To characterize skeletal imaging features of scurvy in a pediatric case series. Read More
