RESUMEN
BACKGROUND: To evaluate the diagnostic accuracy of sonographic assessment of diaphragmatic dimensions and excursions in predicting Continuous Positive Airway Pressure (CPAP) failure in preterm neonates with respiratory distress. METHODS: Prospective cohort study among preterm neonates less than 34 weeks of gestation who were hemodynamically stable and either admitted with respiratory distress or who developed respiratory distress shortly after admission to the NICU and having Silverman-Anderson Score (SAS) ≥ 3/10 were included. We performed sonographic assessment of diaphragmatic dimensions and excursions before and one hour ±30 minutes after application of CPAP. 'CPAP failure' was defined as combined outcome of the need of surfactant and/or upgradation of respiratory support within first 72 hours after a trial of CPAP. Clinical parameters and diaphragmatic measurements were compared between CPAP failure and success groups. RESULTS: Of 62 participants, 20 (32%) failed CPAP. On binomial logistic regression (after adjustment for gestational age and birth weight), initial SAS, higher diaphragmatic excursion (both left and right, before and after CPAP application), lower left hemidiaphragm diaphragmatic thickness fraction (DTF) (before CPAP application) and lower right DTF (after CPAP application) were independent predictors of CPAP failure. However, the receiver-operating characteristics curves showed that excursions of right and left hemi-diaphragm both before and after CPAP application, had highest accuracies in predicting CPAP failure (AUC 0.84, 0.80 and 0.86, 0.78, respectively; p < .001). CONCLUSION: Diaphragmatic excursion can be a useful parameter to predict the failure of CPAP in preterm neonates with respiratory distress.
RESUMEN
Solid pseudopapillary neoplasm (SPN) is an extremely rare tumor with low malignant potential which is generally located in the tail of the pancreas. The prevalence of SPN has increased with the recent advancement in radiological imaging. CECT abdomen and Endoscopic ultrasound-FNA are excellent modalities in preoperative diagnosis. Surgery is the main treatment modality of choice and a successful R0 resection is curative. We present a case of solid pseudopapillary neoplasm and included a summary of the current literature to provide a reference for the management of this rare clinical entity.

A criss-cross heart is an uncommon congenital rotational anomaly. It accounts for less than 0.1% of all congenital heart defects. The anomaly is characterized by crossing of the atrioventricular connections caused by rotation of the heart about its long axis. It is commonly associated with diverse cardiac defects. Cardiac CT imaging of criss-cross heart is sparse. We present a case of 1-year-old child with chief complaints of bluish discoloration of the body and fast breathing. Cardiac CT revealed atrial situs solitus, criss-cross-atrioventricular connections, atrioventricular discordance, double outlet right ventricle and dextro-malposed great arteries (Van Praagh S,D,D).
RESUMEN
The association of aortopulmonary (AP) window with total anomalous pulmonary venous connection (TAPVC) has so far not been reported. We report a unique case of an 8-month-old child who presented with congestive cardiac failure and severe pulmonary arterial hypertension. Initial echocardiography revealed supracardiac TAPVC. Cardiac computed tomography showed the presence of Type I AP window along with the TAPVC. In the presence of severe pulmonary hypertension and dilated right ventricle, AP window may easily be missed if not actively looked for.
RESUMEN
Aortic dissection usually presents as an acute emergency and less commonly presents as chronic dissection. Two-dimensional and transoesophageal echocardiographic features of aortic dissection generally show dissection flap, dilated aorta and aortic regurgitation. We report a very unusual and extremely rare case of a 40-year-old female patient with chronic aortic dissection presenting as functional double aortic valve.

Aortic atresia with an associated ventricular septal defect and adequate sized left ventricle is extremely rare. We present two cases in which an alternate diagnosis was suggested on echocardiography because the hypoplastic aortic trunk was missed due to its small caliber. The final diagnosis was, however, clinched on dual source computed tomography, which not only showed the thin aortic trunk but also clearly depicted the coronary artery origins from the hypoplastic aortic root. To the best of our knowledge, use of multi-detector computed tomography in aortic atresia with well developed left ventricle has not been reported in literature till date.
RESUMEN
Intra-arterial injections during CT scan examinations are a rare occurrence in day-to-day radiology practice but are of potential significance when they do occur. They render an imaging study non-diagnostic, and for imaging techniques like CT scan, expose patient to undue radiation dose. Equally disturbing for both patient and clinicians, including radiologists, is the need for repeat imaging. For certain emergency indications, such an event may yield erroneous results and severely hamper patient's management. We report one such event that occurred in our cardiac CT scan section with the aim to raise awareness about such events among our colleagues.
