Giant cystic hygroma associated with venous aneurysm

Congenital superior caval vein aneurysm in a newborn with cystic lymphangioma: a rare case report

“…In a series of 15 patients with mediastinal cystic hygroma reported by Joseph et al, 6 eight of them also had venous aneurysms, with the majority involving the superior caval vein. Gorenstein et al 7 reported two cases of cystic hygroma in association with venous malformations. This association may be because of a common embryological origin of the venous and lymphatic systems 3 …”

“…After birth, the neonate had congestive heart failure signs followed by respiratory arrest. A second case 7 concerned a fetus with an ultrasound evidence of a neck mass detected prenatally. The fetal echocardiogram performed at 23 weeks showed a superior caval vein aneurysm in the absence of other structural heart defects.…”

Pediatric jugular vein aneurysm (phlebectasia): report of two cases and review of the literature

“…There are conflicting data regarding the most common location of venous aneurysms. The most common site reported in older literature is the superior vena cava and its tributaries [10], although venous aneurysms were found most frequently in the lower extremity in the largest case series to date [4]. Terminology used to describe abnormal dilation of veins is similarly ambiguous.…”

Subdural hygroma associated with axillary cystic hygroma

“…Reports associate the development of various noncontiguous venous anomalies as well as intracranial lesions in patients with cystic hygroma. One report revealed two distinct cases of newborn infants with large cystic hygroma associated with venous aneurysm, discovered prior to the operative removal of the hygroma [8]. Likewise, another report presented a case of a 4-year-old girl with cystic hygroma of the neck diagnosed at age of two years [9].…”
