A previously healthy 10-month-old girl was seen by her pediatrician for evaluation of conjunctivitis and rhinorrhea. On physical examination, a mass on the right side of the abdomen was incidentally identified. She had no fever, vomiting, diarrhea, or abdominal pain. Hemoglobin level and white blood cell count were normal. A frontal abdominal roentgenogram (Fig 1), ultrasound scan (Fig 2), and a computed tomogram (Fig 3) of the abdomen were obtained.
Denouement and Discussion
Amputated Calcified Ovary
At surgery, the mass was attached to the omentum, and the initial impression was of an omental cyst. However, absence of the right ovary and the fimbriated end of the right fallopian tube suggested an ovarian origin of the mass. Pathologic evaluation revealed a thin cyst wall, fibrous stroma, multiple areas of calcification, foci of hemorrhage, and small blood vessels. There was no epithelial differentiation or cellular atypia. No ovarian tissue was identified in the specimen.
