RESUMO
Pyriform sinus fistulae (PSF) are rare branchial pouch anomalies. In most previously described cases the anomaly is located on the left side. PSF should be suspected in cervical inflammatory processes (cervical abscesses and types of suppurative thyroiditis). We report two cases of acute thyroiditis and deep cervical abscesses secondary to PSF, which were diagnosed and treated in our hospital in the last 2 years. Both presented inflammatory cervical masses associated with painful swallowing, high fever and laboratory findings compatible with acute infection. In both cases the diagnosis of PSF was confirmed by barium esophagogram. Cervical ultrasonography and computed tomography were also performed. The treatment of choice consists of broad-spectrum antibiotic therapy during acute exacerbation and subsequent fistulectomy. Definitive surgical treatment prevents recurrences.

Simple renal cysts are infrequently diagnosed in children. Technique improvements in pediatric uroradiology lead to more frequent recognition. Authors review urographic and ultrasound studies of five simple renal cysts in children, between two days and seven years, seen during the last five years.

We reviewed the abdominal sonograms of thirty three infants presenting with vomiting. Thirty patients were clinically suspected of having hypertrophic pyloric stenosis. The thickened pyloric muscle was seen as a hypoechoic mass with strong central echoes, situated medial to the gallbladder, and anterior to the right kidney and caval vein, in transverse and longitudinal sections respectively. The muscle thickness measured between 3.8 and 7 mm. These findings were found in thirty infants, in 27 of whom the diagnosis was clinically suspected, and the other three were presumed to have gastroesophageal reflux. All of them had subsequent confirmation of hypertrophic pyloric stenosis by upper gastrointestinal tract examination and/or surgery. Real time ultrasound is considered a useful, quick, reliable and non invasive method to confirm the hypertrophic pyloric stenosis in infants with vomiting.
