Unformatted text preview: indings of an anterior lucency of hemithorax. Increased sharpness of mediastinal border. Increased pneumothorax 2 forms of aorta coarctation Juxtaductal (adult) type lies at or just distal to the ductus arteriosus. Preductal (infantile, rare) form generally is a long-segment narrowing. Coarctation Bicuspid associated cardiac VSD. of aorta aortic valve. PDA. anomalies Common abdominal masses of 1 month to 2-year-olds? Wilms tumor. Neuroblastoma. Mass from intussusception. Common causes of bilateral lung hyperexpansion Asthma. Bronchiolitis. Cystic fibrosis. Common complications ofstrictures (40%). Anastomotic leakage (14% to 21%). Recurrent fistula (3% to 14%). Esophageal dysmotility. GER. Anastomotic esophageal atresia repair Complete transposition of the great vesselscongenital heart disease with increased pulmonary blood flow. Positions of aorta and PA are reversed. Aorta arises anteriorly from RV. PA arises posteriorly from LV. VSD, ASD, or PDA allow for survival. Most common form of cyanotic (D-transposition) Congenital Hutch diverticulum Adjacent to ureterovesical junction. Increased incidence of VUR. Congenital pulmonary hypoplasia of ipsilateral pulmonary artery. Sometimes associated with tetralogy of Fallot or persistent truncus arteriosus. Hypoplasia or absence Cor triatriatum cause of obstruction of venous emptying into LA. Pulmonary veins empty into a common vein incorporated into the LA. Partial membrane creates an extra chamber along the posterosuperior LA. Rare Corrected transposition inversion with functional correction of transposition. Blood circulates through RA to LV to PA to lungs to LA to RV to aorta to body. Anatomic RV functions as LV and vice versa. Aorta lies anteriorly and to the left hence L-transposition. Ventricular of the great vessels (L-transposition) CSF Pseudocyst VP shunt tip fluid collection causing shunt malfunction. CT findings of acute appendicitis Distended appendix greater than 6mm. Fatty infiltration (stranding). Appendicolith (20-40%). Complications of perforation: fluid collections and free air. Cystic adenomatoid malformation containing dysplastic adenomatous tissue with communicating cysts of variable sizes. Vary from solid lesion to multiple tiny cysts to large, thin-walled cysts. May mimic congenital lobar emphysema. Cysts can enlarge leading to respiratory distress. Usually are unilateral and can affect any portion of the lung. Congenitallung lesion Dermoid versus teratoma Dermoids contain only ectodermal elements. Teratomas contain elements from all dermal layers. Describe course ofumbilical artery, Proceeds caudad in iliac vessels, Ascends left of midling in abdominal aorta. Enters umbilical artery catheter? Describe course of umbilical vein catheter? ductus venosus and into inferior vena cava. Pass into left portal vein through Dextrocardia Cardiac apex lies to the right of the spine. Levocardia is the normal position of the cardiac apex. Dextroversion Right-sided rotation of heart. RA and RV become more posterior. LA and LV lie anterior. Chamber inversion does not occur. DiGeorge syndrome aplasia. Absence of parathyroid glands. Cardiovascular anomalies. Faulty development of third and fourth pharyngeal pouches. Thymic Distinguishers ofcommon in neuroblastoma: Calcification. Spinal involvement. Nodal encasement. More neuroblastoma from Wilm's tumor? Distinguishes GI duplication single layer rather than a double layer (gut ultrasound seen with GI duplication cysts. Cyst wall has a cyst from Mesenteric and omental cysts at signature) Distinguishing ileal atresia from meconium ileus Air-fluid levels in the dilated small bowel are more commonly seen with ileal atresia. Ileal atres...
