Abstract

The solitary fibrous tumor (SFT) is a rare spindle cell tumor originating from the mesenchyme and was first described in pleural tissue in 1931. I had a case referred to me by ENT surgeon thinking as sac swelling and on clinical examination it was firm, non-tender , slightly adherent to underlying soft tissue, no bony defect, non-pulsatile , non-reducible 25 mmx 20 mm in size, located just above the sac area on supero-medial side of his right orbit. Only most important finding was syringing was patent lachrimal passage. Typical characteristic magnetic resonance imaging features of orbital SFTs are iso- or hypointense signals on T1 and T2-weighted images, with marked enhancement. A positive cluster of differentiation 34 (CD34) staining is an important diagnostic clue favoring SFT. Some orbital SFTs are infiltrating, aggressive or recur with malignant transformation, therefore, regular long-term follow-up after complete excision is mandatory.
