Clinicoradiologic differences between orbital schwannoma and cavernous venous malformation: a retrospective comparative case series.

ABSTRACT: To compare the clinical and radiological characteristics, and surgical outcomes of orbital schwannoma and cavernous venous malformation (CVM). We retrospectively compared 13 and 26 patients with biopsy-proven orbital schwannoma and CVM, respectively, analyzing clinical features, magnetic resonance imaging (MRI) and computed tomography (CT) features (including dynamic contrast enhancement [DCE] imaging, apparent diffusion coefficient [ADC] and CT attenuation), surgery type, and outcomes. In both the schwannoma (mean age, 45.0 ± 16.7 years; 53.8% females) and CVM (mean age, 50.2 ± 8.6 years; 61.5% females) groups, gradual proptosis was the most common symptom (53.8% and 46.2%; mean measurements of 3.0 ± 1.97 mm and 2.5 ± 1.64 mm, respectively. Both groups had a common intraconal location (61
