Ruptured corpus luteal cyst: CT findings.

Choi HJ, Kim SH, Kim SH, Kim HC, Park CM, Lee HJ, Moon MH, Jeong JY - Korean J Radiol (2003 Jan-Mar)

Bottom Line: In five of six cases, the cystic contents showed high attenuation.Peritoneal fluid was present in all cases, and its attenuation was higher, especially around the uterus and adnexa, than that of urine present in the bladder.In a woman in whom CT reveals the presence of an ovarian cyst with an enhancing rim and highly attenuated contents, as well as highly attenuated peritoneal fluid, a ruptured corpus luteal cyst should be suspected.

ABSTRACT

Objective: To evaluate the CT findings of ruptured corpus luteal cysts.

Materials and methods: Six patients with a surgically proven ruptured corpus luteal cyst were included in this series. The prospective CT findings were retrospectively analyzed in terms of the size and shape of the cyst, the thickness and enhancement pattern of its wall, the attenuation of its contents, and peritoneal fluid.

Results: The mean diameter of the cysts was 2.8 (range, 1.5-4.8) cm; three were round and three were oval. The mean thickness of the cyst wall was 4.7 (range, 1-10) mm; in all six cases it showed strong enhancement, and in three was discontinuous. In five of six cases, the cystic contents showed high attenuation. Peritoneal fluid was present in all cases, and its attenuation was higher, especially around the uterus and adnexa, than that of urine present in the bladder.

Conclusion: In a woman in whom CT reveals the presence of an ovarian cyst with an enhancing rim and highly attenuated contents, as well as highly attenuated peritoneal fluid, a ruptured corpus luteal cyst should be suspected. Other possible evidence of this is focal interruption of the cyst wall and the presence of peritoneal fluid around the adnexa.

Figure 4: A 19-year-old woman with severe pelvic pain and a negative pregnancy test. At contrast-enhanced CT, the wall of the cystic mass (arrow) is well enhanced. Note the presence of high-attenuated fluid in the cul-de sac and dependent portion of the cyst.

Mentions: The mean diameter of the cysts was 2.8 (range, 1.5-4.8) cm; three were oval and three were round, and there was no septation. Mean maximum thickness of the cyst wall was 4.7 (range, 1-10) mm; in all six cases it showed strong enhancement (Figs. 1, 2B, 3B, 4), with interruption or discontinuity in three (50%) (Figs. 1, 2B, 3B). In five of the six cases (83%), the cystic content was highly attenuated, representing intracystic hemorrhage (Figs. 1, 2A, 3A, 4). In all cases, high attenuation, due to ascites, was present, especially around the uterus and adnexa, and at surgery this was shown to be due to hemoperitoneum with clot formation (Figs. 2A, 3A, 4).
