Vomiting is a protective reflex that results in forceful ejection of stomach contents up to and out of the mouth. It is a common complaint and may be the presenting symptom of several life-threatening conditions. It can be caused by a variety of organic and nonorganic disorders; gastrointestinal (GI) or outside of GI. Acute gastritis and gastroenteritis (AGE) are the leading cause of acute vomiting in children. Important life threatening causes in infancy include congenital intestinal obstruction, atresia, malrotation with volvulus, necrotizing enterocolitis, pyloric stenosis, intussusception, shaken baby syndrome, hydrocephalus, inborn errors of metabolism, congenital adrenal hypoplasia, obstructive uropathy, sepsis, meningitis and encephalitis, and severe gastroenteritis, and in older children appendicitis, intracranial mass lesion, diabetic ketoacidosis, Reye's syndrome, toxic ingestions, uremia, and meningitis. Initial evaluation is directed at assessment of airway, breathing and circulation, assessment of hydration status and red flag signs (bilious or bloody vomiting, altered sensorium, toxic/septic/apprehensive look, inconsolable cry or excessive irritability, severe dehydration, concern for symptomatic hypoglycemia, severe wasting, Bent-over posture). The history and physical examination guides the approach in an individual patient. The diverse nature of causes of vomiting makes a "routine" laboratory or radiologic screen impossible. Investigations (Serum electrolytes and blood gases,renal and liver functions and radiological studies) are required in any child with dehydration or red flag signs, to diagnose surgical causes. Management priorities include treatment of dehydration, stoppage of oral fluids/feeds and decompression of the stomach with nasogastric tube in patients with bilious vomiting. Antiemetic ondansetron(0.2 mg/kg oral; parenteral 0.15 mg/kg; maximum 4 mg) is indicated in children unable to take orally due to persistent vomiting, post-operative vomiting, chemotherapy induced vomiting, cyclic vomiting syndrome and acute mountain sickness.

Children with cancer are at increased risk of life-threatening emergencies, either from the cancer itself or related to the cancer treatment. These conditions need to be assessed and treated as early as possible to minimize morbidity and mortality. Cardiothoracic emergencies encompass a variety of pathologies, including pericardial effusion and cardiac tamponade, massive hemoptysis, superior vena cava syndrome, pulmonary embolism, and pneumonia. Abdominal emergencies include bowel obstruction, intussusception, perforation, tumor rupture, intestinal graft-versus-host disease, acute pancreatitis, neutropenic colitis, and obstructive uropathy. Radiology plays a vital role in the diagnosis of these emergencies. We here review the clinical features and imaging in pediatric patients with oncologic emergencies, including a review of recently published studies. Key radiological images are presented to highlight the radiological approach to diagnosis. Pediatricians, pediatric surgeons, and pediatric radiologists need to work together to arrive at the correct diagnosis and to ensure prompt and appropriate treatment strategies.
