Dermoid cyst of the ovary: computed tomography diagnosis of an unusual case

Dermoid cyst is a common benign tumour of the ovary. Eighty percent of these tumours are discovered in premenopausal women. The authors report a case of dermoid cyst of the left ovary, which was diagnosed in a 78-year-old-woman on the basis of computed tomography (CT) findings. Radiologic findings consistent with ovarian dermoid cyst are discussed, with reference to the role of CT as a diagnostic tool.
