RESUMO
OBJECTIVE: Dandy-Walker syndrome is a set of abnormalities of the posterior fossa including three modalities: classic Dandy-Walker malformation, Dandy-Walker variant and mega-cisterna magna. Our objective is clarify the differential diagnosis among these entities. MATERIAL AND METHOD: Descriptive and retrospective study of Dandy-Walker cases diagnosed at our Department during the last five years plus a review of the related Medical literature. RESULTS: Three cases of Dandy-Walker modalities are reported: one case of classic Dandy-Walker malformation, one case of Dandy-Walker variant, and one case of false Dandy-Walker. In the first two cases the patients underwent legal abortion, whereas in the last one a healthy male newborn was delivered in the week 38 of gestation. CONCLUSIONS: Malformations in the posterior fossa, including Dandy-Walker syndrome, are still a challenge in prenatal diagnosis. Technical developments in imaging, such as in three-dimensional sonography and magnetic resonance, allow higher resolution and multiplanar images for an easier diagnose. There is a high rate of false positive, particularly before the 18th week of gestation. It is advisable not to establish a final diagnose before that week.

Ovarian steroid cell tumors represent less than 0,1% of all ovarian tumors. These tumors normally appear in adult women, producing virilization due to the secretion of testosterone. They may have occasionally a malignant behavior, but when they present during adolescence. We report the case of a 49-year-old woman with an ovarian steroid cell tumor concurrent with an ovarian fibrothecoma, which was an incidental finding, remaining the patient asymptomatic before the diagnosis. Several aspects of the symptomatology, diagnosis and treatment are discussed in this article.
