Hemangioma of the cavernous sinus
in a child
An 11-year-old boy presented with diplopia and right cranial nerve VI paresis. MRI demonstrated a T2-
neous enhancement. The carotid artery was not narrowed (figure). Slow growth prompted endoscopic
transsphenoidal resection. Microscopy demonstrated a vascular tumor with bland endothelial cells and no mitoses.
Hemangiomas of the cavernous sinus rarely occur in children. Marked T2 hyperintensity and progressive
nodular centripetal enhancement are common.1Preoperative diagnosis is important to avoid hemorrhage at
surgery. They are often mistaken for more common meningiomas, which usually show T2-isointensity and
carotid artery narrowing.

FigureHemangioma of the cavernous sinus
Axial T1-weighted (A) and coronal T2-weighted (B) images show an expansile 3.5 ? 2.6 cm tumor in the right cavernous
sinus with T1 hypointense and marked T2 hyperintense signal. Coronal (C) and axial (D) contrast T1-weighted images
acquired several minutes apart reveal characteristic early heterogeneous and late homogeneous enhancement.
