Wagr Syndrome

Wilm’s tumour, aniridia, genitourinary abnormalities, and mental retardation (WAGR) syndrome is a rare genetic disorder with an estimated prevalence of 1 in 500,000 to 1 million. It is a contiguous gene syndrome due to deletion at chromosome 11p13 in a region containing WT1 and PAX6 genes. Children with WAGR syndrome mostly present in the newborn/infancy period with sporadic aniridia. The genotypic defects in WAGR syndrome have been well established. However, antenatal ultrasonographic presentation of this syndrome has never been reported. Prenatal diagnosis of this condition is possible in some cases with careful ultrasound examination of classical and nonclassical manifestations of this syndrome. The key point for this rare diagnosis was the decision to perform chromosomal microarray analysis after antenatal diagnosis of absent corpus callosum and absent cavum septum pellucidum, as this finding mandates search for potentially associated genetic disorders. We report a case of WAGR syndrome diagnosed prenatally at 29-week gestation. The diagnosis of the anomaly was based on two- and three-dimensional ultrasound as well as fetal MRI scan and microarray analysis. The ultrasonographic findings included borderline ventriculomegaly, absent corpus callosum, and absent cavum septum pellucidum. Cytogenetic results from the amniotic fluid confirmed WAGR syndrome. Parental karyotype was normal, with no evidence of copy number change, deletion, or rearrangement of this region of chromosome 11.

Anatomical Basis

Corpus callosotomy offers useful palliation for selected patients with medically intractable seizures, particularly those with uncontrolled and disabling drop attacks. Here the authors present their technique for performing a corpus callosotomy that allows for complete sectioning of the callosum while avoiding entry into the lateral ventricles. The anatomical basis for the technique is the presence of a definable cleft just ventral to the corpus callosum in the midline, formed by the fusion of the two laminae of the septum pellucidum. This small cleft is typically present even in the absence of a cavum septum pellucidum on MR imaging. The authors have found that dividing the body of the corpus callosum by exploiting the cleft of the septum pellucidum in the absolute midline is a simple and expeditious way to perform a callosotomy without entering the lateral ventricles.

Velum Interpositum

Los quistes intracraneales de la línea media anterior se pueden encontrar en tres formas: cavum septum pellucidum, cavum vergae y cavum velum interpositum. El cavum vergae es una extensión del cavum septum pellucidum en dirección posterior a las columna del fórnix y el foramen de Monro. Aunque no está presente en todos los fetos, cuando se observa durante la evaluación ecográfica prenatal puede ser mal diagnosticado como un quiste de la línea inter-hemisférica con pronóstico incierto. Se presenta un caso de una embarazada de 18 años quien acudió a la consulta prenatal a las 32 semanas. Durante la evaluación ecográfica se halló una lesión quística eco-negativa de 20 x 12 milímetros de diámetro, rectangular, intracraneal, presencia de cuerpo calloso y sin evidencia de hidrocefalia compresiva. El cariotipo fue normal. Se consideró el diagnóstico de quiste del cavum vergae. Se obtuvo un recién nacido normal posterior a parto vaginal espontáneo. La resonancia magnética después del parto confirmó el diagnostico.

Stereotactic Guidance

AbstractColloid cyst is a rare benign intracranial lesion. Due to its embryologic origin and development, it is commonly located within the third ventricle, though it also presents at various locations. Its location within cavum septum pellucidum is rarely reported. Operative approaches to such lesion can be challenging and misleading due to intraoperative variations. However, surgical resection in such locations are simplified and perfected with stereotactic guidance. A case of colloid cyst within the cavum septum pellucidum and the importance of stereotactic guidance in precisely reaching the lesion, thus minimizing the dissection of corpus callosum, are discussed.

A case of prenatal diagnosis of the corpus callosum lipoma at 32–33 weeks of gestation is presented. In a consultative examination, a hyperechoic formation with clear contours was found in the projection of the septum pellucidum, occupying the rostrum, genu, and truncus of corpus callosum, without signs of intratumorally blood flow in the color Doppler mapping mode. The prenatal diagnosis of "callosum lipoma" was established, confirmed after the birth of a child during magnetic resonance imaging.
