Multicystic Encephalomalacia:Report of One Case / 中国医学科学院学报

The magnetic resonance imaging findings of multicystic encephalomalacia are featured by bilateral frontal large cystic lesion with corpus callosum involvement,evident heterogeneous enhancement of the lesion margin,ring hyperintensity on diffusion weighted imaging,and high choline peak and low N-acetylaspartate peak of the enhanced lesion margin on magnetic resonance spectroscopy.This article reports a case of multicystic encephalomalacia.

A case of multicystic encephalomalacia in a surviving twin after intrauterine death of co-twin / 대한산부인과학회잡지

The antepartum death of a fetus in a twin pregnancy may cause significant risk of mortality and morbidity in the surviving infant. Especially, one fetal demise of a twin pregnancy in the second or third trimester is an uncommon and difficult problem in the management of pregnancy. In this report, we present a case of single intrauterine death in a twin gestation diagnosed in the 27th week of pregnancy and the surviving fetus exhibits multicystic encephalomalacia three weeks later, antenatally.

Two Cases of Multicystic Encephalomalacia in a Surviving Co-twin with One Intrauterine Fetal Death / 대한주산의학회잡지

Various anatomical defects have been described in the surviving co-twin who had stillborn, macerated monozygotic co-twin with disseminated intravascular coagulation. The suggested mechanism was the transfer of emboli or thromboplastic materials of dead fetus to co-twin through placental vascular anastomoses. Multicystic encephalomalacia is the condition defined anatomically by the presence of multiple cavities in the great part of both cerebral hemispheres. The most common pathogenesis is circulatory disturbance caused by neonatal asphyxia during the perinatal period. We experienced two cases of monozygotic twin with deceased co-twin at 26 weeks, 33 weeks of gestation and confirmed the diffuse multicystic encephalomalacia by cranial ultrasonography and MRI in a surviving co-twin. Only one patient has been followed who showed spastic cerebral palsy and severe mental retardation. We report two cases of multicystic encephalomalacia in a surviring co-twin with a intrauterine fetal death and its related literatures.
