摘要:

Inflammation can manifest itself in similar sonographic findings regardless of which organ is inflamed. Edema of connective tissues and inflammatory hyperemia in and around the inflamed organ are two of these findings. The purpose of this article is to show the importance of connective tissue edema and hyperemia as sonographic findings in inflammatory conditions. We will discuss these findings in a wide spectrum of different inflammatory conditions. We believe that abnormal thickening and increased echogenicity of fat and loose areolar connective tissues and color Doppler and duplex sonographic evidence of inflammatory hyperemia are demonstrable in most acute (and some chronic) inflammatory conditions. Furthermore, their presence strongly suggests an inflammatory etiology and makes other etiologies, such as neoplasm, less likely.

摘要:

A retrospective analysis was performed on 1,209 patients who underwent breast surgery for a suspicious finding on a clinical, sonographic, or mam-mographic examination. The clinical role of sonomammography (SM) relative to X-ray mammography (XRM) was evaluated. In 643 patients benign pathologic conditions, such as fibroadenomas or fibrocystic changes, were found. The false-negative rate of SM (133 of 589 = 22.6%) was significantly lower than that of XRM (222 of 643 = 34%). In 73 cases with clinically and mammographically suspicious findings, SM indicated the correct benign diagnosis; on the other hand, XRM indicated a correct benign preoperative diagnosis only when there were clinically and sonographically suspicious findings in 45 cases. The false-positive rate for 566 carcinomas, including 61 in situ cancers, however, was nearly the same for both methods (SM: 47 of 498 = 9.44%; XRM: 51 of 542 = 9.41%). Clinically occult breast carcinomas were detected only by SM in 35 cases and only by XRM in 34 cases. The sensitivity and specificity of SM were 77.2% (451 of 584) and 90.7% (456 of 503) in comparison to 68.9% (491 of 713) and 89.2% (421 of 472) for XRM. Following breast cancer resection, sonography of the epigastric region for the early detection of liver metastases is part of the routine follow-up in most German centers. Sonography of the chest wall and its lymphatic drainage area is, however, rarely used for routine follow-up. From 1987 to 1992, 120 local recurrences and lymph node metastases were diagnosed, and 31 of these cases (25.8%) were detected exclusively by sonography. These occult local recurrences and lymph node metastases were significantly smaller lesions than were found in cases where there was a clinical suspicion of disease. Since the decline in survival following the detection of a local recurrence depends mainly on the size of the mass, the prognosis for breast cancer patients after a local recurrence can be improved by the routine use of sonography for the earliest possible detection. Sonography is supedorio mammography in the detection of recurrences after breast-conserving — surgery with or without the implantation of a prosthesis. During the period between 1987 and 1992 in Münster, 16 of 61 (26.2%) clinically occult local recurrences after breast-conserving surgery were detected exclusively by sonography and six of 61 (9.8%) exclusively by mammography. There was an obvious learning curve in the routine use of sonography in tumor follow-up examinations. In 1987 only two of 14(14.3%) clinically occult local recurrences and lymph node metastases were detected correctly by sonography, whereas in 1992, eight of 22 (36.4%) were detected.

摘要:

Diagnosis of ovarian masses can be difficult because many pathologic conditions can affect the ovary and have similar clinical manifestations and radiologic appearances. A specific diagnosis of a given adnexal mass requires a judicious use of different imaging modalities. Each of the three major imaging modalities, ultrasound (US), computed tomography (CT). and magnetic resonance imaging (MRI). plays a specific role in the evaluation of adnexal masses. This review of multimodality imaging of adnexal masses describes and illustrates the role of the different modalities in evaluating a spectrum of gynecologic masses.
