Corpus luteum cyst rupture with consequent hemoperitoneum is a common disorder in women in their reproductive age. This condition should be promptly recognized and treated because a delayed diagnosis may significantly reduce women’s fertility and intra-abdominal bleeding may be life-threatening. Many imaging modalities play a key role in the diagnosis of acute pelvic pain from gynecological causes. Ultrasound study (USS) is usually the first imaging technique for initial evaluation. USS is used to confirm or to exclude the presence of intraperitoneal fluid but it has some limitations in the identification of the bleeding source. Contrast-enhanced computed tomography (CT) is the imaging modality which could be used in the acute setting in order to recognize gynecological emergencies and to establish a correct management. Magnetic resonance imaging (MRI) nowadays is the most useful technique for studying the pelvis but its low availability and the long acquisition time of the images limit its usefulness in characterization of acute gynecological complications. We report a case of a young patient with hemoperitoneum from hemorrhagic corpus luteum correctly identified by transabdominal USS and contrast-enhanced CT.

Purpose. To evaluate the correlation between MRI and histopathological findings in patients with mammographically detected 3–5 BI-RAD (Breast Imaging Reporting And Data Systems) microcalcifications and to allow a better surgical planning. Materials and Method. 62 female Patients (age ) with screening detected 3–5 BI-RAD microcalcifications underwent dynamic 3 T contrast-enhanced breast MRI. After 30-day (range 24–36 days) period, 55 Patients underwent biopsy using stereotactic vacuum-assisted biopsy (VAB), 5 Patients underwent stereotactic mammographically guided biopsy, and 2 Patients underwent MRI-guided VAB. Results. Microhistology examination demonstrated 36 malignant lesions and 26 benign lesions. The analysis of MRI findings identified 8 cases of MRI BI-RADS 5, 23 cases of MRI BI-RADS 4, 11 cases of MRI BI-RADS 3, 4 cases type A and 7 cases type B, and 20 cases of MRI BI-RADS 1-2. MRI sensitivity, specificity, positive predictive value, and negative predictive value were 88.8%, 76.9%, 84.2%, and 83.3%, respectively.
