The role of tomosynthesis in breast cancer staging in 75 patients.

OBJECTIVES: Compare tomosynthesis to mammography, ultrasound, MRI, and histology for the detection and staging of BI-RADS 4-5 anomalies, as a function of breast composition, lesion location, size, and histology. PATIENTS AND METHODS: Seventy-five patients underwent mammography, tomosynthesis, ultrasound, and MRI. The diagnostic accuracy of the different examinations was compared. RESULTS: The sensitivities for detection were as follows: 92.5% with MRI, 79% for ultrasound, 75% for tomosynthesis, and 59.5% for mammography. Tomosynthesis improves the sensitivity of mammography (P=0.00013), but not the specificity. The detection of multifocality and multicentricity was improved, but not significantly. Tomosynthesis identified more lesions than mammography in 10% of cases and improved lesion staging irrespective of the density, but was still inferior to MRI. The detection of ductal neoplasia was superior with tomosynthesis than with mammography (P=0.016), but this was not the case with lobular cancer. The visualization of masses was improved with tomosynthesis (P=0.00012), but not microcalcifications. Tomosynthesis was capable of differentiating lesions of all sizes, but the smaller lesions were easier to see. Lesion sizes measured with tomosynthesis, excluding the spicules, concurred with histological dimensions. Spicules lead to an overestimation of the size. CONCLUSION: In our series, tomosynthesis found more lesions than mammography in 10% of patients, resulting in an adaption of the surgical plan.

[Spontaneous renal forniceal rupture with suspicious ovarian mass]. / Urétéro-hydronéphrose avec rupture du fornix sur masse ovarienne suspecte.

Extravasation of urine following rupture of the renal fornix is a rare complication mostly caused by obstruction secondary to distal ureteric stones. This 35-year-old woman was referred with back pain. Her CT scan revealed rupture of the renal fornix secondary to a pelvic mass. Laparoscopy subsequently confirmed this to be an ovarian abscess. We report the first case of spontaneous renal forniceal rupture secondary to pelvic inflammatory disease.

Imaging of inflammatory myofibroblastic cervical tumours: a case report.

Among the family of mesenchymatous tumours, inflammatory myofibroblastic tumours (IMT) are an increasingly recognised and defined lesional group due to the great many studies and recent publications. The aetiopathogenicity is still not fully understood. It seems that an immune origin is involved in the pathological process. These masses result from the proliferation of fibroblast and lymphocyte cells associated with collagen wickerwork. Most often benign, they may affect any organ or supporting tissue. However, these lesions remain non-specific and are difficult to distinguish from malignant tumoral processes. Here resides the value of imaging: to make the diagnosis, guide the biopsy and thereby avoid early damaging surgery or an aggressive medical treatment. This is all the more valid since recent papers have shown that corticotherapy of short duration is currently the first intention treatment We here describe the case of a female patient presenting disseminated erythematous lupus who presented a cervical myofibroblastic tumour. The early diagnosis allowed for the initial medical care, which turned out to be effective without resorting to surgery.

Internal hernia of the broad ligament: CT diagnosis for laparoscopic management.

One per cent of cases of mechanical occlusion of the small intestine are caused by internal hernias, the rarest type being an internal hernia through the broad ligament of the uterus, and representing approximately 5% of cases. While "conventional" treatment of mechanical occlusions of the small intestine is based on laparotomy, a laparoscopic approach is feasible in nearly half of cases, with an acceptable rate of morbidity. Preoperative diagnosis has for a long time been difficult but the usefulness has recently been emphasized of computed tomography. We report the cases of two patients who presented an internal hernia of the right broad ligament diagnosed with CT who afterwards underwent laparoscopic surgery.
