Abstract Cystic hygroma is the most frequent fetal neck mass in first-trimester ultrasound US.
It consists of fluid-filled posterior or posterolateral cavities in the neck. The overall prognosis is poor as there is a high association with chromosomal and structural anomalies and progression to hydrops and fetal demise. Cystic hygroma is a type of lymphangioma with large dilated cystic lymph spaces which usually occur in the neck or axillae in infants. The mediastinal type of cystic hygroma is rare less than 1 and is usually not discovered until adulthood because of its asymptomatic nature and deep location.
This is an example of a large cystic hygroma which is compromising the airway.
Reference number 3 below discussed the potential airway compromise that cystic hygromas can cause. Congenital remnants like cystic hygroma can be bilateral. These are confluent cystic low-density lesions. Step 3 By exclusion we can conclude that these are bilaterally enlarged lymph nodes with homogeneous enhancement.
Homogeneous enhancement is typical for lymphoma.
Central necrosis is more typical for squamous cell carcinoma metastases. A subdural hygroma radiographically appears as a crescentic near-CSF densitysignal accumulation in the subdural space that does not extend into the sulci and rarely exerts significant mass-effect 5. Vessels rarely cross through the lesion in contrast-enhanced studies see cortical vein sign 1. Small cystic spaces extend into the right parotid and masticator spaces arrows consistent with cystic hygroma lymphatic malformation.

There is a 10 to 15 percent chance a cystic hygroma may recur after surgery. This is an outpatient non-surgical procedure to limit the effects of cystic hygroma A radiologist uses ultrasound to help guide a thin needle into the cyst. Cystic Hygroma Lymphangioma Lymphatic Tumor. Introduction One of the most commonly presented lymphat - ic malformation is cystic lymphangioma or cystic hygroma CH.
Lymphangiomas are divided in three groups.
Lymphangioma simplex cavernous lymphangioma and CH1. CH is a misnomer for a benign lesion that appears as an enlarged mass of. A cystic hygroma characteristically appears as a multiloculated cystic mass with septa of variable thickness that contain solid components arising from the cyst wall or the septa. Correlation of the sonogram with the pathologic specimen demonstrated that the echogenic component corresponded to a cluster of abnormal lymphatic channels too small.
Cystic hygroma is a birth defect that involves a malformation of the lymph system.
Cystic hygroma may be apparent in fetuses as early as the first trimester. Ultrasound MRI and CT scan may be used in diagnosis. The prognosis of cystic hygroma is variable. Fetal cystic hygroma is a congenital malformation of the lymphatic systemThe lymphatic system is a network of vessels that maintains fluids in the blood as well as transports fats and immune system cellsCystic hygromas are single or multiple cysts found mostly in the neck region.
Cystic hygroma belongs to a group of diseases recognized as lymphatic malformations and is also known as macrocystic lymphatic malformation or cystic lymphangioma.
In cystic hygroma shown in the. Cystic hygroma also known as water-tumor is a benign malformation of lymphatic vessels which usually occurs when the lymphatic system fails to communicate with the normal jugular vein. It can occur in the head neck axilla cervico-facial regions groin and below the tongue 2. Cystic hygroma is a rare congenital malformation of the lymphatic system.
In most centers surgical excision is considered to be the optimal mode of treatment.
Spontaneous resolution of cystic hygroma was briefly described in the literature with unsatisfactory results. Between 1970 and 2003 14 patients were diagnosed to have cystic hygroma 13 cervical and 1 axillary. Of the sacs of the cystic hygroma. Cystic hygromas are congenital vasculolymphatic FIG 1.
