Chromosomal analysis showed a X-chromosome monosomy – 45,X[21], consistent with TS. Case 4 Case 4.

References Townsend Sabiston Surgery, Saunders, p. At MRI, two lesions presented hypointense signal on T1-weighted sequence and hyperintense on T2-weighted sequence, with hypointense thin septations inside on both sequences fetuses 2 and 3and one was heterogeneous, with a predominantly hyperintense signal on the T2-weighted sequence fetus 1 Figure 2. Analysis of cystic hygroma, ascitic, and pleural fluids by conventional lymphocyte culture and fluorescent in situ hybridization.

The pathogenesis of subdural hygromas is not entirely understood. Subdural hygromas are encountered in all age-groups but are overall most common in the elderly 7. All the three lesions were successfully resected without any impairment to the future life of the neonates Figure 3. The examination can be performed without sedation and provides an excellent resolution of the fetal anatomy 4. Cystic hygroma in the fetus and newborn. Prognosis Recurrence rate after surgical excision: If the CH is multiloculated, it is possible to puncture and analyze different regions especially due to the possibility of mosaicism 4.

Received November 3, In the three cases evaluated in the present series, the lesions were cystic hygromas, two of them predominantly cystic with thin septations inside, and one heterogeneous.

At 21 weeks, there was no fetal heartbeat and spontaneous elimination of the fetus occurred two days later. These images are a random sampling from a Cisfico search on the term “Cystic Hygroma.

The newborns two girls and one boy were submitted to surgery right after the birth, except for one of them who was evaluated by MRI after uigroma week of life to restudy the lesion extent, confirming the pre-natal findings. Content is updated monthly with systematic literature reviews and conferences.

The MRI images were independently analyzed by the radiologist who performed the comparative US study and by a second radiologist, both with experience in fetal medicine, to evaluate the lesions site, size and extent, seeking a consensus on the establishment of a correlation between the findings of the two imaging methods utilized.

The patients were 20 years old patient 129 years old patient 2 and 34 years old patient 3with mean age of 27 years, and underwent MRI one week after US with, respectively 24, 35 and 33 gestational weeks mean US is the method of choice for screening fetal malformations Vessels rarely cross through the lesion in contrast-enhanced studies see cortical vein sign 1.

The most echogenic portion of the lesion correlates with groups of small and abnormal lymphatic channels 2.

MRI has been recognized as a useful complementary method, especially in cases where US results are dubious or undetermined 5,7,11, After the analysis of the three cases of cystic hygromas by US and MRI, the authors have concluded that MRI plays a significant role as an ally of obstetric US in the evaluation of fetal lesions because of its higher accuracy in the determination of these tumors extent and adjacent structures invasion, allowing a better surgical planning and, therefore improving the quality of life of these patients.

In such cases the prognosis is more reserved, so the prenatal diagnosis of lymphangiomas becomes extremely important, allowing a more appropriate counseling and treatment. In the third case, the lesion was heterogeneous with predominant hyperintense signal on T2-weighted sequences.
