Patient Data

Transabdominal and transvaginal examination.

The uterus is of normal appearance and anteverted. It was mobile and non-tender during the examination. The myometrium is of homogenous attenuation, but there 2 small focal lesions in the anterior aspect, measuring 20 and 13 mm, most in keeping with fibroids. The endometrial thickness is 12 mm and in keeping with secretory phase.

The left ovary is not identified. The right ovary measures 18 cc in total volume and contains 12 follicles. There is a 2.6 cm x 3.3 cm focal structure within the right ovary with a ring of fire colour Doppler signal surrounding it and cystic spaces containing low-level echoes. The appearances are in keeping with a haemorrhagic corpus luteum cyst.

Conclusion:

Appearances and in keeping with a haemorrhagic right corpus luteum.

Case Discussion

The ring of fire sign is useful to help identify the corpus luteum, which often can be haemorrhagic. Rarely, haemorrhage from a corpus luteum can be extensive resulting in haemoperitoneum.
