[Echographic study in evaluating gastrointestinal pathology]. / L'indagine ecografica nella valutazione della patologia del tratto gastrointestinale.

The echographic study of the gastrointestinal tract is hampered by the presence of gas that prevents the long-range penetration of the ultrasound beam. However the presence of a mass with a central echogenic region surrounded by a sonolucent wall of over 1.5 cm is characteristic of intestinal pathologies. A study of 23 patients with gastrointestinal disorders in whom echography revealed specific pictures is presented.

Swelling of the submandibular glands after administration of low-osmolarity contrast agent: Ultrasound findings.

Swelling of the salivary glands occurring after injection of iodine based contrast agent is a rare late adverse reaction. Only a few cases in the literature report such diagnostic findings. We present our color Doppler ultrasound findings in a case of swelling of both submandibular glands occurring after administration of iodinated contrast agent.

An unusual case of hematuria caused by a foreign body in the bladder: US and radiologic findings.

The presence of a foreign body in the bladder or urethra is generally the result of autoerotic acts, psychiatric problems, or therapeutic interventions. It can cause hematuria, pain, and abscess formation, which may lead the patient to seek medical care, but the diagnosis is not always easy. This report describes a man who presented with several months' history of hematuria. Ultrasonography revealed a foreign body in the bladder, and the diagnosis was confirmed by abdominal radiography. The object, which was endoscopically removed, proved to be the ceramic sheath of an endoscopic resector that had been used 2 years earlier for transurethral resection of the prostate.
