Acardic twining is a rare congenital anomaly, usually in monozygotic twins. This condition is characterized by the absence or rudimentary development of fetal hear, and associated with various anomaly(especially with anecephalus). The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. We recently experienced a case of acardius acephalus associated with a normal term male infant, so present with a brief review of the literature.

The corpus callosum is the main interhemispheric connection in human brain. Agenesis of corpus callosum may partial or complete, and it may have not functional abnormalities. Its prenatal sonographic diagnosis is difficult because of fetal head position, especially in a cephalic presentation. We experienced a case of complete agenesis of corpus callosum. The prenatal sonographic findings was disproportionate dilatation of lateral ventricle, which were suggestive finding of agenesis of corpus callosum or hydrocephalus. We could confirm the diagnosis of complete agenesis of corpus callosum by postnatal MRI.

Sclerosing stromal tumor of ovary is extremely rare benign neoplasm, occurring predominently in the second and third decades of life. It was first described by Chalvardjian and Scully in 1973 and by Damjanov in 1975 as distinctive subtype of other ovarian sex cord stromal tumor. This tumor differs from the fibroma, thecoma and lipid cell tumor clinically and pathologically by showing pseudolobular pattern, prominent vascularity and cell heterogeneity. We report a case of sclerosing stromal tumor of the ovary in 30-year-old woman with brief review of the literature.
