In our study, the performance of the fetal karyotype by CH puncture allowed the correct diagnosis and genetic counseling. Ascites was also noted later. Subdural hygromas refer to the accumulation of fluid in the subdural space. To evaluate three cases of cervical lymphangioma with magnetic resonance imaging and correlating with sonographic findings. Ultrasound findings, such as CH and hydrops, may assist in its detection 1. Subdural hygroma versus atrophy on MR brain scans: 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.

Therefore, the use of CH fluid as an alternative sample for fetal karyotyping may be considered when conventional invasive procedures can not be performed. The three patients had a Cesarean section between their 37th and 38th gestational weeks, and underwent postnatal follow-up.
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.
However, in cases of prenatal detection, it is important to perform a fetal karyotyping considering that lymphatic dysplasias are associated with chromosomal abnormalities 3.
All the lesions were located in the posterior cervical region, two of them at left fetuses 1 and 3and one at right fetus 2. Related Bing Images Extra: Zen 1 csitico Jorge Alberto B.
Unable to process hiigroma form. Small to middle-sized lesions may regress along the gestation If the CH is multiloculated, it is possible to puncture and analyze different regions especially due to the possibility of mosaicism 4. Congenital cystic masses of the neck: Although these lesions tend to involve and, sometimes, invade adjacent structures, they do not present malignant potential 1.
Most of times, lymphangiomas are diagnosed at the second and third trimesters of gestation, and identified as multiseptated, thin-walled cystic masses in the fetal head and neck region 8.
Check for errors and try again. The karyotype is performed through lymphocyte culture from cystic cells that has a mitotic index and metaphases quality compatible with a blood lymphocyte culture. The objective of the present study is to report three cases of cervical lymphangiomas in fetuses evaluated by routine US, and correlating the findings with alterations observed at fetal MRI.
Prognosis Recurrence rate after surgical excision: Use hjgroma the fluid obtained by puncture of cystic hygroma: Additionally, MRI demonstrated involvement of the auricula in the case of fetus 2, and intrathoracic extension of the lesion towards the upper mediastinum in the case of fetus 1, which had not been demonstrated at US.
It can be diagnosed at different life stages, including the intrauterine period.

cisgico The use of CH fluid, obtained through direct hygroma puncture, can be used as an alternative procedure 2. In cases where mass-effect is radiographically demonstrated, it may be neurosurgically evacuated 5. A lymphangioma characterized by the presence of thin-walled cavernous lymphatic spaces. Three pregnant women between the 24th and 35th gestational weeks, with sonographic findings suggestive of fetal cystic hygroma, were submitted to magnetic resonance and subsequently to a new ultrasonography for correlation of imaging findings.
However, as found in the present report, this type of sample or even fetal blood by cordocentesis becomes unable to higroam due to obstructions by large cysts or oligohydramnios 2.
Prenatal diagnosis is usually performed by karyotype analysis from amniotic fluid samples. The aim of our study was to report a fetus with Turner syndrome TS diagnosed by karyotype from cystic hygroma CH fluid, emphasizing the applications and importance of this procedure. Igroma cisticoIgromaLinfangioma cistico. The relation between cystic hygromas and soft tissues of the neck is most clearly demonstrated at MRI 2. Analysis of cystic hygroma, ascitic, and pleural fluids by conventional lymphocyte culture and fluorescent in situ hybridization.
At 21 weeks, there was no fetal heartbeat and spontaneous elimination of the fetus occurred two days later.
Their growth is slow, but these lesions may present a rapid increase in size in cases of hemorrhage or trauma 2. Otolaryngology – Hematology and Oncology Pages.
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 ccistico 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. Fetal tumors, although uncommon, constitute unique circumstances in the management of pregnant patients, representing significant medical and ethical dilemmas 1.
Patients should address specific medical concerns with their physicians. This failure leads to an enlargement of lymphatic channels, this theory cisticoo the one most commonly accepted, that of cystic hygroma.

References Townsend Sabiston Surgery, Saunders, p. In the present three-case series evaluating cervical lymphangiomas, the authors considered that MRI was complementary to US, with a similar role in the evaluation of the lesions site, size and content.
In cases of lymphangiomas, the method determines more accurately the lesion extent and its relationship with the adjacent structures, allowing a more appropriate surgical planning. The knowledge on the specific types of tumors and respective biological characteristics is necessary for an appropriate counseling and management of these patients 1.
In the third case, the lesion was heterogeneous with predominant hyperintense signal on T2-weighted sequences. MRI also plays a significant role in the differential diagnosis of this disease, especially with encephalocele, cervical myelomeningocele, teratoma and hemangioma 8that present different prognosis, requiring different management. The three newborns were successfully submitted to surgery and had the diagnosis confirmed by means of histopathological evaluation.
