Small cell carcinoma of the ovary, hypercalcemic type is a rare ovarian tumor. This tumor has three distinctive clinical features: i) an occurrence in young women, ii) the presence of hypercalcemia in 62% of cases, and iii) a high degree of malignancy. The radiologic findings of the tumors are usually large and a predominantly solid mass with internal necrosis, hemorrhage and cystic degeneration. We report on the CT and MRI findings of an ovarian small cell carcinoma, hypercalcemic type in a 17-year-old female who presented 1 month abdominal discomfort with weight loss.
