Ovarian Sertoli-Leydig Tumour in a Postmenopausal Female With Virilisation: Magnetic Resonance Imaging Findings.

Sertoli-Leydig cell tumours (SLCTs) of the ovary are uncommon sex cord-stromal tumours that may cause virilisation and menometrorrhagia. Herein, we describe the magnetic resonance imaging features of SLCT in a 75-year-old female who exhibited virilisation with elevated androgen and oestrogen levels. The tumour appeared as a well-defined multilobulated mass. Measuring 8 cm in diameter with flow voids and cavitation, and showed high signal intensity in the early and delayed phases. The uterine myometrium showed high signal intensity and a clear junctional zone on T2-weighted images, and the clitoris was enlarged. A solid ovarian mass demonstrating intense enhancement with flow voids associated with elevated oestrogen levels and virilisation could suggest SLCT.
