Acute sialadenitis as adverse reaction to iodinated contrast. / Sialoadenitis aguda bilateral como reacción adversa a contraste yodado.

Swelling of the salivary glands after administration of iodinated contrast is a very rare adverse reaction. Its etiology is not clear and although it has a benign course associated complications have been reported. We report two cases of acute bilateral sialadenitis after intravenous iodinated contrast in 60 and 63 year-old men who underwent a computed tomography scan in the previous days.

[Gastric adenomyoma clinically simulating hypertrophic pyloric stenosis]. / Adenomioma gástrico que simula clínicamente una estenosis hipertrófica de píloro.

Gastric adenomyomas are extremely uncommon benign tumors in children. On histologic examination, these tumors have an epithelial component similar to pancreatic ducts. We present a case of a pyloric adenomyoma that clinically simulated hypertrophic pyloric stenosis in a newborn girl. Imaging tests, fundamentally magnetic resonance imaging, were very important in the characterization and diagnosis of this entity.
