“…These rare tumors, when large, may be associated with agenesis of the corpus callosum and other dysraphic findings including: meningomyelocele, encephalocele, cranium bifidum, hypertelorism, median clefting, and others, symptomatology includes headaches, seizures, and mental retardation. 57 It appears that approximately 50% of the patients may be asymptomatic, usually in association with smaller size lipomas, in the absence of associated anomalies. In these cases the lipomas usually are located upon the superior surface of the intact corpus callosum, and may only be detected as an incidental finding at autopsy.…”

“…In these cases the lipomas usually are located upon the superior surface of the intact corpus callosum, and may only be detected as an incidental finding at autopsy. 57 Following the report of sonographic diagnosis of lipoma of the corpus callosum in neonates by Sauerbrei and Cooperberg, 58 Christensen et al 57 described an unusual case in which prenatal ultrasonography at 40 weeks' gestation disclosed a small midline hyperechoic intracranial structure of unknown significance. Neonatal cranial ultrasonography at 24 hr of life confirmed a hyperechoic smoothly marginated zone immediately adjacent to the superior aspect of the corpus callosum, measuring 2.7 X 0.7 cm in size and extending posteriorly from the midportion of the corpus curving around the splenium.…”

Our objective was to review current literature pertaining to prenatal ultrasonography of various fetal intracranial neoplastic and non-neoplastic tumors. To this goal, all manuscripts published in the English language regarding this topic obtained from a MEDLINE search from 1966 through January 1998 were selected and reviewed. Additional sources were identified through cross-referencing. Intracranial fetal tumors are extremely rare and precise diagnosis is dependent on histology examination of tissue obtained at subsequent surgery or autopsy. Currently, prenatal ultrasonographic findings associated with the following fetal intracranial tumors have been described: teratomas; neuroepithelial tumors including: glioblastoma, astrocytoma, gangliocytoma, medulloblastoma, choroid plexus, and papilloma; and mesenchymal tumors. Non-neoplastic fetal intracranial tumors are even less frequent and include: unilateral megalencephaly, heterotopia, and lipoma of the corpus callosum. Cardinal ultrasonographic findings associated with fetal intracranial tumors include: echogenic and semicystic space occupying lesions with or without distortion of normal symmetrical intracranial (usually midline) structures, calcifications, craniomegaly, polyhydramnios, obstructive hydrocephaly, high-output cardiac failure (hydrops fetalis), the presence of other associated structural anomalies, and infrequently abnormal cerebral Doppler flow velocimetry.
