RESUMO
A term baby was born with findings of edema, harsh murmur, and hypertension. Pregnancy course was complicated by hydrops fetalis. Upon birth, blood work did not reveal any abnormalities, but an echocardiogram showed patient in high-output heart failure. A computed tomography (CT) chest, abdomen, and pelvis revealed narrowing of aorta in the thoracic region to distal iliac and renal arteries, consistent with mid-aortic syndrome. Mid-aortic syndrome, which results in the narrowing of thoracic or abdominal aorta, is a rare cause of hypertension, especially in newborns. This case elucidates the importance of maintaining a broad differential when encountering an uncommon problem in a newborn.
RESUMO
Salter-Harris type I fractures of the distal tibia are commonly seen in paediatrics and management of such fractures follows an algorithm established in the literature. Despite this, osteonecrosis of the distal tibia can subsequently develop. Osteonecrosis or avascular necrosis is cell death that occurs secondary to trauma, metabolic disturbances, sickle cell disease, or medication side effect. It most frequently affects the femur, talus, or humerus, and rarely the tibia. Radiographs and MRI are pivotal in making a timely diagnosis in order to minimize patient discomfort. To the best of our knowledge, there has only been one previous documented case of osteonecrosis following a Salter Harris Type I distal tibial fracture. Here, we present the second such case.
