Shard-like calcifications in retroperitoneal teratomas.

Retroperitoneal teratomas can have characteristic roentgenographic findings. Three children with that neoplasm had roentgenographic assessments of the tumor which revealed similar "shard-like" calcifications. The effect of the tumor on the kidneys produced hypertension in all the patients which abated post-operatively. Extensive imaging evaluations in similar patients seems unnecessary since the findings are virtually pathognomonic. Only a single urinary tract study and plain film investigation of the abdomen are advised prior to expeditious surgery.
