Carotid cavernous fistula in CNS choriocarcinoma

Abstract

Carotid artery-cavernous sinus fistulas (CCFs) are infrequently reported in the pediatric population, and are rarely reported in conjunction with CNS neoplasms. The authors present a 7-year-old girl with CNS choriocarcinoma who acutely developed left eye proptosis and conjunctival injection. Computed tomography angiography revealed a CCF, which was endovascularly embolized with detachable coils. There may be a direct cause-and-effect relationship between choriocarcinoma and development of CCFs.

Primary Intracranial Choriocarcinoma: MR Imaging Findings

“…3,15,16 Various sites of PICCC have been reported, including the pineal region 3,5,[17][18][19][20][21] and the suprasellar or parasellar region. 5,15,22,23 Less common sites include the lateral ventricle, 2 pituitary fossa, 24 basal ganglia, 2,25 and septum pellucidum. 6 In our study, all tumors were located in the pineal (6/7) and suprasellar (1/7) regions.…”

Acute abducens nerve palsy as a presenting feature in carotid-cavernous fistula in a 6-year-old girl

“…1) ). Five of these patients required surgical intervention, such as embolization, and 1 underwent spontaneous closure [ 5 ], [ 6 ], [ 7 ], [ 8 ], [ 9 ], [ 10 ], [ 11 ]. Carotid-cavernous fistulas causing increase in intraocular pressure in infants and young children may lead to eyeball elongation and anisometropic amblyopia.…”
