In modern times scurvy is a rarely encountered disease caused by ascorbic acid (vitamin C) deficiency. However, sporadic cases of scurvy persist, particularly within the pediatric population. Recent individual case reports highlight an increased incidence of scurvy among patients with autism or developmental delay, with isolated case reports detailing the magnetic resonance imaging (MRI) findings of scurvy in these pediatric populations. We present the MRI findings of scurvy in four patients with autism or developmental delay, and review the literature on MRI findings in pediatric patients with scurvy. Despite its rarity, the radiologist must consider scurvy in a pediatric patient with a restricted diet presenting with arthralgia or myalgia.

A spectrum of findings in gastric volvulus exists. Mesenteroaxial volvulus has greater morbidity and mortality. Radiographic findings of spherical gastric dilatation, paucity of distal gas and diaphragmatic elevation are suggestive of acute volvulus, particularly in patients with predisposing factors.

We report a case of extramedullary hematopoiesis presenting as an adrenal mass in a young male with hereditary spherocytosis. The unilateral adrenal mass was discovered during an abdominal ultrasound performed for jaundice. CT and MR imaging were subsequently performed, followed by an excisional biopsy at the time of splenectomy and cholecystectomy. Although extramedullary hematopoiesis is a rare cause of an adrenal mass, the diagnosis must be considered in any patient with a history of a congenital hemolytic disorder such as hereditary spherocytosis. In this regard, the morbidity of an unnecessary procedure may be avoided.

The lymphomas were commonly extra nodal, and infiltrative rather than mass-like. The recognition of the tumors was often delayed due to confusion with the known infectious complications in AT patients.

Non-bilious vomiting in the newborn is common. Etiologies include both surgical and medical conditions. Gastroesophageal reflux, soy or milk protein allergy, and prostaglandin-induced foveolar hyperplasia are among the medical causes. Surgical entities include gastric antral webs, pre-ampullary duodenal and pyloric atresia, and hypertrophic pyloric stenosis. We report the unique case of an 8-day-old girl who presented with gastric outlet obstruction secondary to infantile myofibromatosis.
