US is the method of choice for screening fetal malformations Unable to process the form.
Started inthis collection now contains interlinked topic pages divided into a tree of 31 specialty books and chapters. Antepartum assessment of fetal cystic lymphangioma by magnetic resonance imaging. Thank you for updating your details. The three patients had a Cesarean section between their 37th and 38th gestational weeks, and underwent postnatal follow-up.
Subdural hygroma | Radiology Reference Article |
The karyotype test results using Hifroma puncture are obtained in four days, while by amniocentesis they range from days 5 Figures 1 and 2. In the third case, the lesion was heterogeneous with predominant hyperintense signal on T2-weighted sequences.
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. Hematology and Oncology Chapter. The three patients were previously informed about the procedure and signed a term of free and informed consent.
The advantages inherent to this imaging method include higher accuracy in the evaluation of soft tissues because of the better tissue contrast resolution besides the multiplanar capability 11playing a significant role in the evaluation of lesions extent, most of times providing a more comprehensive and better fetal evaluation when performed in the sagittal plane 9.

No racial or sex predominance is reported, and the entity is subdivided into four histological types, cystic hygroma being the most frequently found 1,2. Related Bing Images Extra: Subdural hygromas are encountered in all age-groups but are overall most common in the elderly 7.
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 Search other sites for ‘Cystic Hygroma’. Tumors size, location, content and extent were evaluated both at magnetic resonance imaging and ultrasonography.
There was no family history of birth defects or genetic disorders. First-trimester screening revealed an increased nuchal translucency measurement, cervical cystic hygroma and head and trunk subcutaneous edema. In many cases, it is considered an epiphenomenon of head injury when it is called a traumatic subdural 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 one week of life to restudy the lesion extent, confirming higdoma pre-natal findings.

Chromosomal analysis showed a X-chromosome monosomy – 45,X, consistent with TS. 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 pathogenesis of subdural hygromas is not entirely understood. 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. 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.
There was oligohydramnios, which prevented the execution of amniocentesis. Accepted after revision August 27, cistivo You can also scroll nigroma stacks with your mouse higrma or the keyboard arrow keys.
To evaluate three cases of cervical lymphangioma with magnetic resonance imaging and correlating with sonographic findings. A comprehensive review of fetal tumors with pathologic correlation. Fetal CH is characterized by single or multiple lymphatic congenital cysts and is often found associated with TS 3.
Lymphangiomas are congenital malformations of the lymphatic system caused by a failure in the drainage from the primordial cisrico sac 1,3. MRI has been recognized as a useful complementary method, especially in cases where US results are dubious or undetermined 5,7,11, Case 1 Case 1. Content is updated monthly with systematic literature reviews and conferences.
Case 7 Case 7. Hygroma cystikusCystikus lymphangiomaCystikus hygroma. The karyotype is performed through lymphocyte culture from cystic cells that has a mitotic index and metaphases quality compatible with a blood lymphocyte culture. Sanders RC, Blakemore K. In our study, the performance of the fetal karyotype by CH puncture allowed the correct diagnosis and genetic counseling.
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. References Townsend Sabiston Surgery, Saunders, p. Case 4 Case 4.
