RESUMO
Rhabdomyosarcoma (RMS) is the most common malignant pelvic tumor in the young child, occurring typically in children aged 2-4 years. It arises from the prostate or the trigone of the bladder in boys, and from the vagina or uterus in girls. We report a case of bladder rhabdomyosarcoma and discuss the ultrasonographic images. The mass produced filling defect on the contrast cystogram and also was demonstrated with CT.

Idiopathic dilatation of the pulmonary artery (IDPA) is a rare congenital disease which is usually detected fortuitously on chest x-ray, thus radiologists must be aware of this clinical entity. This report describes four cases to which Magnetic Resonance Imaging (MRI) played a major role in diagnosing IDPA and in detecting the concomitant findings observed in this disease. MRI is a non-invasive procedure with many advantages for the accurate and reproducible measurement of artery structures, which makes it the preferred option for combined use with echocardiography in the diagnosis and follow-up of patients with IDPA.
