La estenosis congénita del orificio piriforme (ECOP) es una entidad poco frecuente que causa obstrucción de la vía respiratoria alta en neonatos y niños pequeños. Su diagnóstico se realiza mediante tomografía computarizada (TC) de las fosas nasales cuando el diámetro transverso máximo del orificio piriforme es menor de 11mm. Se presenta el caso de una paciente con un cuadro de dificultad respiratoria episódica desde el nacimiento. Se le realizó TC de las fosas nasales y se le diagnosticó ECOP. También se analizaron las anormalidades típicamente asociadas (AU)
Congenital nasal pyriform aperture stenosis (CNPAS) is an unusual cause of upper respiratory obstruction in neonates and infants. The diagnosis is made with Computed Tomography (CT) of nasal cavity when maximum transverse diameter of the pyriform aperture is less than 11mm. We present a patient with breathing difficulty since birth. The diagnosis of CNPAS was made after a CT examination of the nasal cavity. We also discuss typically associated abnormalities (AU)

Malformation of the vein of Galen is an uncommon intracranial vascular anomaly that is mainly seen in pediatric patients. It presents with diverse manifestations and variable severity. It consists of dilated deep venous structures in the system of Galen, fed by abnormal arteriovenous communications in the midline. Magnetic resonance imaging and magnetic resonance angiography are better than computed tomography for the study of this condition. The case reported here joins the set of rare cases in which a vein of Galen malformation is discovered in an adult.

La agenesia de las glándulas parótidas es una entidad infrecuente cuya etiología es variada, asociándose en algunos casos a imperforación del conducto lacrimonasal. La clínica más frecuente de presentación es la xerostomía, revelando el examen físico de la cavidad oral la ausencia del punto de drenaje de la glándula. Las técnicas de imagen, Tomografía Computarizada (TC) y Resonancia Magnética (RM) son diagnósticas, evidenciando la ausencia de tejido glandular en su correspondiente localización, considerándose complementario es estudio funcional con la gammagrafía. Presentamos el caso de una niña de cuatro años con agenesia bilateral de glándulas parótidas que asociaba estenosis del conducto lacrimonasal, que acudió por clínica de xerostomía
Agenesis of the parotid glands is an uncommon entity which etiology is variable, that in some cases associates imperforated lacrimal puncta. Xerosotmia is most frequently clinical presentation, and physical examination of oral cavity shows abscence of glandular papillae. Imaging techniques, Computarized Tomography (CT) and Magnetic Resonance Imaging (MRI) are diagnostics, showing absence of glandular tissue in its corresponding location, scintigraphic functional study is a complementary test. We report a case of four year-old child with bilateral agenesis of parotid glands with lacrimonasal duct stenosis associated, presented with xerostomia
