RAPOSO, Joana Vasconcelos et al. The “Black Garland” sign in ovarian fibromatosis. Acta Obstet Ginecol Port [online]. 2022, vol.16, n.1, pp.45-47.  Epub Mar 31, 2022. ISSN 1646-5830.

Ovarian fibromatosis refers to a rare benign phenomenon where there is a tumor-like ovarian enlargement up to 6-12cm in size due to diffuse ovarian fibrosis and it is more frequently seen unilaterally. It is characterized by a proliferation of collagen-producing spindle cells surrounding normal ovarian structures, thus causing thickening of the superficial cortex and enlargement of the ovary. It affects predominantly young women and common clinical manifestations include abdominal pain, menstrual irregularities, hirsutism and virilization. Ovarian fibromatosis may mimic malignant ovarian tumors due to similar presentation and radiological findings. The “black garland sign” refers to a marked T2 hypointense thick rim of fibrous tissue surrounding the ovary in the setting of ovarian fibromatosis on magnetic resonance imaging (MRI).

Keywords : Ovarian fibromatosis; Black garland sign; MR imaging.
