[Is differential diagnosis between soft tissue paraneural lesions and optic nerve tumors using computer tomography possible?].

The results of computer tomogram images analysis of 32 patients (32 orbits) with soft tissue orbital tumors are presented. 22 patients appeared to have cavernous hemangioma, 10--optic nerve meningioma. The technique of three dimensional reconstruction of orbital soft tissue is described and its diagnostic value in patients with cavernous hemangioma and optic nerve meningioma is analyzed. The density of lesions and its variability were studied. Indications for two and three dimensional imaging were proposed to differentiate these tumors.
