All the lesions were found in the posterior and lateral cervical space. However, in cases of prenatal detection, it is important to perform a fetal karyotyping considering that lymphatic dysplasias are associated with chromosomal abnormalities ciztico. 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. 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 higrlma 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.
Despite the advanced maternal age, TS is not associated with it. All the lesions under suspicion of being cervical lymphangiomas at obstetric Citsico were confirmed by MRI that, similarly to the previous and comparative US studies, evaluated the lesions site, size and content. Case 4 Case 4.

MR imaging and ultrasound of fetal cervical cystic lymphangioma: The demographics will depend on the underlying cause which includes:. Prenatal diagnosis is usually performed by karyotype analysis from amniotic fluid samples. However, MRI demonstrated to be superior in the correct and more accurate demonstration of lymphangiomas cistioc, allowing an appropriate and individualized surgical planning.
Although this explanation has the benefit of simplicity, it does not necessarily represent a true description of the underlying mechanisms. You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.

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. It is usually found in the neck, axilla, or groin. The most frequently observed pattern of cystic hygromas is that of a mass with iso- or hypointense signal on T1-weighted sequences, depending on the protein content of the lymphatic fluid, and hyperintense on T2-weighted sequences 1,2.

Ultrasound findings, such as CH and hydrops, may assist in its detection 1. Moreover, the diagnosis was important to assess the prognosis. 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.
Cystic hygroma in the fetus and newborn.
The use of CH fluid, obtained through direct hygroma puncture, can be used as an alternative procedure 2. Ultrafast MR imaging of the fetus. Large masses may cause airways compression resulting in death 1. In cases of isolated presentation, lymphangiomas have a good prognosis and most of times should be surgically resected.
All the three lesions were successfully resected without any impairment to the future life of the neonates Figure 3.
Accepted after revision August 27, The pathogenesis jigroma subdural hygromas is not entirely understood. The total examination time was, on average, 20 minutes, with acquisition of T1-weighted sequences repetition time [TR], ms; echo time [TE], 4. Case 5 Case 5. MRI imaging of fetal neck masses with airway compromise: MR imaging of non-CNS fetal abnormalities: There was oligohydramnios, which prevented the execution of amniocentesis.
The three patients were previously informed about the procedure and signed a term of free and informed consent. At 21 weeks, there was no fetal heartbeat and spontaneous elimination of the fetus occurred two days later.
There are four histological types of lymphangiomas:
