Functional megacoloncondition in childhood. Spasm of puborectalis muscle. Prominence of puborectalis sling. Patients can hold large volumes of stool in colon.
GI cystic masses
Duplication cyst. Mesenteric cyst. Meconium pseudocyst. Lymphangioma. Appendiceal abscess.
Helps distinguish obstructive emphysema from results in diminished size of pulmonary vessels due to compression and hypoxia-induced reflex arterial spasm. In compensatory hyperinflation pulmonary vessels are normal or even increased in size.
Obstructive emphysema generally compensatory hyperinflation?
Hemangioendothelioma possiblefailure. Hemorrhage. Jaundice. Hemolytic anemia. Thrombocytopenia (Kasabach-Merritt syndrome) sequestration of platelets. DIC.
High-output cardiac complications
Hepatic adenomas are rare inGlycogen-storage disease reported in association with
Fanconi anemia. childhood but have been type 1. Hurler disease. Severe combined immunodeficiency. Hepatic hemangioendothelioma features? first 6 months of life. Hepatomegaly and high-output congestive heart failure are common. May present with platelet sequestration (Kasabach-Merritt syndrome) or DIC.
Benign. Most diagnosed within
Gallbladder hydrops. Choledochal cyst. Mesenchymal hamartoma. Abscess/parasitic cyst.
Hepatobiliary cystic masses Hepatoblastoma features
Occurs in children under the age of 5 years. May extend into portal veins, hepatic veins, and inferior vena cava. Prematurity is a risk factor. Usually well-circumscribed, solitary mass. May be multifocal.
Hepatoblastoma routes of spread
Local: Portal vein. Hepatic vein. IVC. Lymph nodes. Diaphragm. Peritoneum. Remote: Lungs.
Hepatoblastoma occurs at what age and with what syndromes?
Early childhood, presenting before 3 years of age. Beckwith-Wiedemann syndrome. Familial adenomatous polyposis.
Epidermolysis bullosa effect on esophagus
Hereditary condition. Inflammatory skin and mucosal lesions that can heal with fibrosis. May result esophageal stricture.
Hirschsprung disease features
Contracted aganglionic distal colon. Abnormal peristalsis and inability to effectively evacuate colon. Rectum is always involved. Extent of proximal involvement varies. Colon caliber transition more common in older infants. Tortuosity or corrugation of narrowed aganglionic segment of the colon is commonly seen. Diagnosis made with rectal biopsy. Necrotizing enterocolitis is an uncommon but serious complication. How long does it take for gas to reach the by 12 h in a normal newborn?
May take up to 24 hrs. Occurs rectum in most healthy infants.
Hydrometrocolpos versus hematometrocolpos
Both are congenital vaginal obstructions. Hydrometrocolpos anechoic fluid in the newborn. Hematometrocolpos echogenic blood in the adolescent.
Hypertrophic pyloric stenosis features: weeks of age. Hypertrophy of pyloric muscle. 4 mm or more in thickness. Pyloric channel elongated beyond 15 mm.
