PEDIATRIC CHEST Flashcards
hyperlucent lung; asymmetric. It is also known as Obstructive Bronchiolitis
Swyer-James-Macleod syndrome
NEONATE patient shows a lucency adjacent to the cardiomediastinal silhuoette with as SHARPLY DEFINED CARDIAC or DIAPHRAGMATIC MARGIN
pneumothorax in neonate
- basal pneumothorax (medial) is more common in neonates
Differential diagnosis of neonatal pneumothorax
SKIN FOLD
*absence of thin white pleural line at the interface between the central higher attenuation and peripheral lower attenuation
What is the most common etiology of Pneumonia in INFANT AND YOUNG CHILDREN which has prominent areas of atelectasis that change rapidly “ WANDERING OR SHIFTING ATELECTASIS”
RSV
MC TRUE LUNG MASS in children. A solid mass that ABUTS the PLEURA AND MEDIASTINAL SURFACE
Inflammatory myofibroblastic tumor (IMT), plasma cell granuloma, and xanthogranuloma
MC LUNG mass in a child
pseudomass ( round pneumonia)
MC PRIMARY benign neoplasm in the pediatric population that presents as SOLITARY NONCALCIFIED LOBULAR MASS
Pulmonary Hamartoma
Pulmonart Hamartoma >Pulmonary Chondroma > Respiratory Papillomatosis
MC primary MALIGNANT pulmonary lesion in pediatric population
ENDOBRONCHIAL CARCINOID
PLEUROPULMONARY BLASTOMA
MC primary MALIGNANT pulmonary lesion in pediatric population
ENDOBRONCHIAL CARCINOID
PLEUROPULMONARY BLASTOMA
Pulmonary mass that begins as CYSTIC LESION that progresses to a solid one and occurs in children younger than 6 years old
PLEUROPULMONARY BLASTOMA
*indistinguishable to CPAM
Clues: pneumothorax, multiple lesions and family history (DICER1)
MC ANTERIOR mediastinal mass in children
Lymphoma
MC POSTERIOR mediastinal mass in children
Neurogenic tumor (usually neuroblastoma)
MC BENIGN CHEST WALL mass in pediatric population
Osteochondroma
MC MALIGNANT CHEST WALL mass in PEDIATRIC population
Metastasis
MC PRIMARY MALIGNANT CHEST WALL mass in PEDIATRIC population
RHABDOMYOSARCOMA
MC cause congenital abnormality of the larynx
LARYNGOMALACIA
- MC cause of noisy breathing in infants
*congenital softening of the soft tissue of the pharynx leading to airway collapse
on LATERAL neck radiograph, widening of the retropharyngeal soft tissue is seen in
RETROPHARYNGEAL ABSCESS
*cause by Grp A Strep
* MC mechanism: spread of oropharyngeal flora to the retropharyngeal LN
MC infectious diease of the UPPER AIRWAY that causes BARKING COUGH AND STRIDOR
CROUP/LARYNGOTRACHEOBRINCHITIS
*subglottic trachea
* Pathogen: PARAINFLUENZA
* 6mos to 3 y/o
An UPPER airway infection showing a NARROWING of the SUBGLOTTIC airway with PENCIL POINT OR STEEPLE.
CROUP/ LARYNGOTRACHEOBRONCHITIS
- NORMAL epiglottis and aryepiglottic fold
a more virulent upper airway infection that affects OLDER CHILDREN demonstrating an INTRALUMINAL FILLING DEFECT , likely a SLOUGHED MEMBRANE
BACTERIAL TRACHEITIS aks bacteria/membranous croup
- Moraxella catarrhalis and S. aureus
Swelling of the involve ARYEPIGLOTTIC FOLD AND EPIGLOTTIS
EPIGLOTITTIS
*supraglottis
*Haemophilus influenzae
MCC of PNEUMOMEDIASTINUM in WELL children
Idiopathic
MCC of PNEUMOMEDIASTINUM in SYMPTOMATIC children
asthma
MC lung injury in children
Pulmonary contusion
- with subpleural sparing
