Ultrasonographic evaluation of the gallbladder in mucocutaneous lymph node syndrome.

Abstract
Hydrops of the gallbladder was diagnosed by ultrasonography in 5 out of 10 consecutive patients [children] with mucocutaneous lymph node syndrome (MLNS). Certain signs and symptoms were correlated with the development of hydrops. Follow-up ultrasonography revealed the return of the gallbladder to normal size in 4 out of 4 patients. One patient was lost to follow-up. Hydrops of the gallbladder in patients with MLNS appears to be a self-limiting condition with a benign course.
