“…Fetuses with sacrococcygeal teratoma (SCT) have a high risk of perinatal complications and death. [3][4][5][6][7][8][9][10][11][12][13][14][15] Tumor rupture may occur during labor, particularly if the delivery is uncontrolled; therefore, in some cases with a large extracranial mass, as in our case, cesarean delivery could be considered. Indeed we have previously reported a case of a fetus with a SCT that developed severe anemia following spontaneous rupture of the tumor in utero.…”

“…1,2,5 A preoperative assessment of the extent of invasion is important for antenatal counseling and surgical planning, as occasionally these tumors do have some intracranial involvement. 1,7,8 Additionally, some intracranial teratomas will have secondary orbital extension, which will induce rapid polyhydramnios or hydrocephalus. 1,9,10 Since intracranial extension is important for prognosis, 1,11,12 MRI results may direct prenatal counseling.…”

We report a case of a fetus with a congenital orbital teratoma (COT), in which rupture of the tumor was associated with an intrauterine fetal demise. An ultrasound scan at 27 weeks' revealed a solid and cystic, complex mass in the orbital region with extensive vascularization suggestive of an orbital cystic teratoma. Magnetic resonance imaging (MRI) supported this diagnosis and clarified tumor localization. At 32 weeks', the patient presented with fetal demise and rupture of the mass was noted. Fetal COTs, like sacrococcygeal teratomas, carry the risk of rupture. MRI in utero is useful for evaluating the extent of disease.

“…They are treated by both ophthalmologists and neurosurgeons. [4,36] As Pikus, et al, [33] have emphasized, an exact knowledge of the parasellar anatomy is critical for surgical interventions within this space. Extremely careful preparation is necessary because of the limited blood volume and cardiovascular reserve of young children.…”

Object In this study the authors analyze the peculiarities of the parasellar anatomy and the topography of surgical approaches to the parasellar region (PSR) in human infants. Methods Forty-nine specimens of the PSR obtained at autopsy were studied using microdissection and histological analysis. Important distances between anatomical landmarks were measured with the aid of a dissecting microscope. One serially sectioned specimen was three-dimensionally reconstructed and analyzed on the computer screen by using the authors' new episcopic reconstruction technique. The anatomy of the infant PSR differs distinctly from that of the adult. The parasellar portion of the internal carotid artery (ICA) does not form a siphon, but takes a straight course, and the venous pathways as well as the cranial and sympathetic nerves have different topographical relationships. Analyses of surgical approaches demonstrate that, in young children, the anterolateral approach can be used to reach the pterygopalatine compartment, the superior ophthalmic vein, and those pathological processes that extend from the orbit into the PSR. The approach via Parkinson's triangle can be used in 45% of cases to access the pathological processes that occur in the voluminous space above and behind the posterior flexure of the parasellar ICA. Taking this route, sympathetic nerve fibers passing through the PSR are not at risk, but some arterial branches that run within the lateral wall of the sinus can complicate this approach. Conclusions This study presents a guideline that can assist radiologists and neurosurgeons in the planning and performance of interventions within the PSR of neonates and young children.
