PURPOSE : To describe the US findings of corpus luteum cyst rupture in order to elucidate the associated clinical features.
MATERIALS and METHODS : Twenty patients with proven corpus luteum cyst rupture were included in this study. The
US findings of these patients were retrospectively analyzed in terms of the presence of designable cyst, size of
the cyst, thickness and blood flow of the cyst wall, extension and echogenicity of peritoneal fluid, and involved
site (right or left ovary). We also surveyed the clinical features such as the onset period according to the menstrual
cycle, and the presence of suspectable cause.
RESULTS : Fourteen of the 20 patients revealed designable cysts (mean diameter of 2.6 cm) with thick walled cysts
(mean thickness, 4.6 mm, 2.4-6.8 mm) and increased blood flow. Six patients didn’t reveal any cyst but only
hematoma in adnexa. All patients had hemoperitoneum in the pelvic cavity, and the hemoperitoneum was extended
to Morrison’s pouch in 8 patients and to the subphrenic space in 6. The cysts occurred in the right adnexa
in 15 patients and in the left in 5. Mean interval from the last menstrual period (LMP) was 26 days (13-44days)
and 6 of the 8 patients for whom it had been possible to obtain detailed history taking had had coitus just before
the occurrence of symptom.
CONCLUSION : When women who are hospitalized for acute abdomen and who are in luteal phase reveal US findings
of hematoma or thick-walled cyst in adnexa and hemoperitoneum, a corpus luteum cyst rupture is highly
suspected. In our case study the corpus luteum cyst rupture predominantly occurred in the right side, and the
most suspectable cause was trauma such as coitus in the luteal phase. |
