Methods: We investigated 35 children with a history of urinary tract infection with grayscale and color Doppler ultrasound (US) fol-lowed by a standard voiding cystouretherogram to assess the presence of vesicoureteral reflux. All renal units (individ-ual kidneys) were morphologically normal without evidence of hydronephrosis. Resistive index (RI) was measured at the level of the interlobar arteries. Results: Of a total of 67 kidney units, 3 kidney units yielded no diagnostic results due to technical factors (crying, agitation). 46 kidney units (69%) were not associated with any degree of reflux. 17 kidney units (25%) were associated with low-mid grade reflux (grades I - III). 4 kidney units (6%) were associated with high grade reflux (grades IV - V). No statistically significant correlation was found between the interlobar resistive indices of sonographically normal appearing kidneys and the presence, absence, or degree of vesicoureteral reflux. Conclusions: The results of this study suggest that resistive index measurements taken in the interlobar arteries of sonographically normal appearing kidneys cannot be used to predict the presence or absence of vesicoureteral reflux.展开更多

Chest X-ray showed a right sided tension pneumothorax (PTX) with a large air containing structure at the base of the right hemithorax. The pneumothorax was partially evacuated with needle aspiration at which time the patient became asymptomatic, despite a small residual pneumothorax. CT scan of the chest confirmed a multilocular air-filled structure within the right lower lobe, most likely consistent with a congenital pulmonary airway malformation (CPAM). Subsequently, there was spontaneous resolution of the PTX and CPAM prior to surgical intervention. This case illustrates post-natal spontaneous resolution of a CPAM, thus obviating the need for surgical removal.展开更多
