Therefore, at 18 weeks of pregnancy, a puncture of the CH was held for fetal karyotyping, following a long-term culture. The present study evaluated three pregnant women referred by Instituto Fernandes Figueira, Rio de Janeiro, after the finding of fetal cervical cystic mass at obstetric US. The relation between cystic hygromas and soft tissues of the neck is most clearly demonstrated at MRI 2.
Igroma cisticoIgromaLinfangioma cistico. Fetal CH is characterized by single or multiple lymphatic congenital cysts and is often found associated with TS 3.
Ascites was also noted later. 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.
All the lesions under suspicion of being cervical lymphangiomas at obstetric US were confirmed by MRI that, similarly to the previous and comparative US studies, evaluated the lesions site, size and content. Log in Sign up. All the lesions were located in the posterior cervical region, two of them at left fetuses 1 and 3and one at right fetus 2.
The three newborns were successfully submitted to surgery and had the diagnosis confirmed by means of histopathological evaluation.

It can be diagnosed at different life stages, including the intrauterine period. There was no family history of birth defects or genetic disorders. In most of cases, the higrma is asymptomatic and the size of the lesions is variable 2.
Prognosis Recurrence rate after surgical excision: These images are a random sampling from a Bing search on the term “Cystic Hygroma. It has been proposed that subdural hygromas, at least sometimes, represent prominent subdural effusions in which there is a separation of the dural border cell layer with an accumulation of fluid 7. Hematology and Oncology Chapter. A correct prenatal diagnosis is extremely important, considering that, although cystic hygromas may be isolated malformations 1these lesions are frequently associated with other chromosomal abnormalities, such as Turner syndrome and Down syndrome 1,2,10that should be immediately investigated in case of suspicious diagnosis 8.
Case 5 Case higroja. The vast majority of patients with subdural hygroma are asymptomatic without radiographic evidence of mass-effect, and thus neurosurgical intervention is rarely required 5.
Three pregnant women between the 24th and 35th gestational weeks, with sonographic findings suggestive of fetal cystic hygroma, were submitted to ihgroma resonance and subsequently to a new ultrasonography for correlation of imaging findings. It is usually found in the neck, axilla, or groin. Evaluation of fetal cervical lymphangioma by magnetic resonance imaging and correlation with sonographic findings.

Koshiyama 1 ; Tatiana D. MR imaging of non-CNS fetal abnormalities: Case 1 Case 1. Signs Fluctuant mass usually in neck Mass transilluminates. Cystic hygroma in the fetus and yigroma. This fact was confirmed by the present cases higrma MRI was more accurate than US in the evaluation of the lesions extent, demonstrating the invasion of adjacent structures, with extension towards the pinna of the fetus in one case, and towards the upper mediastinum in another one.
However, as found in the present report, this type of sample or even fetal blood by cordocentesis becomes unable to obtain due to obstructions by large cysts or oligohydramnios 2. Therefore, the use of CH fluid as an alternative hiroma for fetal karyotyping may be considered when conventional invasive procedures can not be performed.
Large masses may cause airways compression resulting in death 1. Patients should address specific medical concerns with their physicians. Case 7 Case 7. Floriani 1 ; Luiza E.

Rapid fetal karyotype from cystic hygroma and pleural effusions. There are other theories regarding lymphangiomas, but the authors have opted for considering that of cystic hygromas, since this is the entity approached by the present study. Otolaryngology – Hematology and Oncology Pages. Magnetic resonance imaging in obstetric diagnosis. Obstetrical magnetic resonance imaging: Prenatal diagnosis of an extensive fetal lymphangioma using ultrasonography, magnetic resonance imaging and cytology.
Definition NCI A benign lymphatic neoplasm usually arising from the neck and characterized by cystic dilation of the lymphatic vessels. Related Topics in Hematology and Oncology. In two cases of the present study, the lesions were hypointense on T1-weighted sequences, and hyperintense on T2-weighted sequences, with thin septations inside. Vessels rarely cross through the lesion in contrast-enhanced studies see cortical vein sign 1.
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. Fetal magnetic resonance imaging can be a useful adjuvant to obstetric ultrasonography in cases of lymphangioma because of its higher accuracy in the determination of these tumors extent and adjacent structures invasion, allowing a better postnatal surgical planning.
In many cases, it is considered an epiphenomenon of head injury when it is called a traumatic subdural hygroma.
As regards the higrona content, US demonstrated predominantly cystic lesions with thin septations inside fetuses 2 and 3and one was heterogeneous fetus 1 Figure 1.
Use of the fluid obtained by puncture of cystic hygroma: Analysis of cystic hygroma, ascitic, and pleural fluids by conventional lymphocyte culture and fluorescent in situ hybridization.
However, in cases of prenatal detection, it is important to perform a fetal karyotyping considering that lymphatic dysplasias are associated with chromosomal abnormalities 3. The karyotype test results using CH puncture are obtained in four days, while cistjco amniocentesis they range from days 5 Figures 1 and 2. However, some symptoms uncommonly reported include
