From: Magnetic resonance imaging of pure ovarian dysgerminoma: a series of eight cases
Ovarian dysgerminoma in a 23-year-old woman with recurrence after surgery. Axial T2w (a), axial contrast-enhanced T1w with fat-suppression (b) MR images show a multilobulated heterogeneous large-sized cystic-solid pelvic mass with interspersed septa and avid enhancement after Gd administration. The mass was surgically removed and stage II dysgerminoma was diagnosed. Two years after surgical treatment, during a routine follow-up, we revealed a recurrence in the right emipelvis, characterized by heterogeneous hyperintense signal on axial T2w (c), high signal and low values on DWI and ADC images (d, e), heterogenous moderate enhancement after Gd administration (f)
