There was oligohydramnios, which prevented the execution of amniocentesis. Prenatal diagnosis is usually performed by karyotype analysis from amniotic fluid samples. In our study, the performance of the fetal karyotype by CH puncture allowed the correct diagnosis and genetic counseling. This fact was confirmed by the present cases where 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.

Subdural hygroma | Radiology Reference Article |

To evaluate three cases of cervical lymphangioma with magnetic resonance imaging and correlating with sonographic findings. MRI imaging of fetal neck masses with airway compromise: 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.

All the lesions were located in the posterior cervical region, two of them at left fetuses 1 and 3and one at right fetus 2. A cystic growth originating from lymphatic tissue. Unable to process the form. 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.


Vessels rarely cross through the lesion in contrast-enhanced studies see cortical vein sign 1.

Hematology and Oncology Chapter. Sanders RC, Blakemore K. Therefore, the use of CH fluid as an alternative sample for fetal karyotyping may be considered when conventional invasive procedures can not be performed.

Use of the fluid obtained by puncture of cystic hygroma: In cases of isolated presentation, lymphangiomas have a good prognosis and most of times should be surgically resected.

In cases where mass-effect is radiographically demonstrated, it may be neurosurgically higro,a 5. Subdural hygroma versus atrophy on MR brain scans: Support Radiopaedia and see fewer ads.

Prognosis Recurrence rate after surgical excision: Central Nervous SystemTrauma. In the third case, the lesion was heterogeneous with predominant hyperintense signal on T2-weighted sequences. 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, some symptoms uncommonly reported include Higorma 1 ; Luiza E.

Case 7 Case 7. Evaluation of fetal cervical lymphangioma by magnetic resonance imaging and correlation with sonographic findings. Lesions extent and adjacent structures invasion were better characterized by magnetic resonance imaging, with appropriate demonstration of invasion of the pinna in one case and invasion of the superior mediastinum in another. Igroma cisticoIgromaLinfangioma cistico.

Antepartum assessment of fetal cystic lymphangioma by magnetic resonance imaging. Content is updated monthly with systematic literature reviews and conferences.

It is usually found in the neck, axilla, or groin. Therefore, at 18 weeks of pregnancy, a puncture of higrom CH was held for fetal karyotyping, following a long-term culture. Case 5 Case 5.

Check for errors and try again. As regards the lesions content, US demonstrated predominantly cystic lesions with thin septations inside fetuses 2 and 3and one was heterogeneous fetus 1 Figure 1.

Despite the advanced maternal age, TS is not associated with it. Fetal CH is characterized by single or multiple lymphatic congenital cysts and is often found associated with TS 3.


These images are a random sampling from a Bing search on the term “Cystic Hygroma. A lymphangioma characterized by the presence of thin-walled cavernous lymphatic spaces. All of the lesions were located in the posterior cervical region, two of them at left and one at right, with mean size of 7. However, MRI demonstrated to be superior in the correct and more accurate demonstration of lymphangiomas extent, allowing an appropriate and individualized surgical planning.

A comprehensive review of fetal tumors with pathologic correlation. There are other cistkco regarding lymphangiomas, but the authors have opted for considering that of cystic hygromas, since this is the entity approached by the present study.

Synonyms or Alternate Spellings: There are four histological types of lymphangiomas: Definition NCI A lymphangioma characterized by the presence of thin-walled cavernous lymphatic spaces. Ultrasound findings, such as CH and hydrops, may assist in its detection 1.

Although this explanation has the benefit of simplicity, it does not necessarily represent a true description of the underlying mechanisms. All these types are formed hirgoma lymphatic channels with endothelial lining separated by a conjunctive tissue stroma 1.

Higroma cístico de face com involução após infecção local

Search other sites for ‘Cystic Hygroma’. The three newborns were successfully submitted to surgery and had the diagnosis confirmed by means of histopathological evaluation. Lymphangiomas are congenital malformations of the lymphatic system caused by a failure in the drainage from the primordial lymphatic sac 1,3.
