Atypical presentation of a case of solitary fibrous tumor of the orbit.
OBJECTIVE
To describe a rare case of solitary fibrous tumor of the orbit in a child, clinically misdiagnosed as arterious hemangioma.


METHODS
A nine-year-old child presented a hard-elastic palpable mass located in the right inferotemporal orbit. Computed tomography, orbital pulsed-wave Doppler and internal carotid artery angiography consented diagnosis of high-vascularization mass probably related to arterious hemangioma with feeder vessel arising from a branch of ophthalmic artery. The orbital mass was surgically removed.


RESULTS
The histological examination showed mesenchimal tumor, CD34 positive, related to solitary fibrous tumor of the orbit.


CONCLUSIONS
Solitary fibrous tumor of the orbit should be considered in the differential diagnosis of arterious hemangioma.
