The Viet Duc Hospital found 6 cases of the postoperative left gauze by ultrasound during 1997-1998. The diagnosis based on the clinical symptoms (infectious sign), operative history, position and size of foreign body. The foreign bodies found earliest in the 20th days and longest in the 4th years after an operation. The form, size and structure of the foreign bodies have not been changed through the round of examination.

Usually a intracranial foreign body eludes the most intent search despite of C-arm fluroscopy and ultrasonography in operative field. And the usual craniotomy increases brain damage by searching brain parenchyme for intracranial foreign body. Recently we experienced stereotaxic removal of intracranial foreign body with Brown-Roberts-Wells(B.R.W.) system. This approach has been used easily and accurately under the local anesthesia. And it was less traumatic procedure. We present a detailed technique of stereotaxic of intracranial foreign body.

Foreign bodies in the maxillofacial area are not commonly seen. If occurred, the immediate removal of foreign bodies is recommended to avoid further complications. The most important thing is a exact localization of foreign bodies using X-rays such as plain radiography, computed tomography, magnetic resonance imaging and ultrasound before treatment. During removal of foreign bodies, tissue should be dissected carefully and complete exploration of the whole wound required.

Meconium peritonitis is a non-bacterial foreign body and chemical peritonitis caused by meconium contamination resulting from bowel perforation during late intrauterine or early neonatal periods. Prenatal ultrasonographic diagnosis of the meconium peritonitis provides the preparation for proper management and decreasing motality and morbidity of the neonate. We have experienced a case of meconium peritonitis diagnosed by ultrasonography at 34+4 gestational weeks and presented this case with a brief review of the literatures.

Foreign bodies, such as surgical sponges or drains, are sometimes retained after surgical procedures.1 Retention of a drain in the breast tissue postoperatively is an unusual complication. This report describes two cases of characteristic sonographic findings related to retained silastic drains following breast surgery.

OBJECTIVE: To determine which mode of ultrasonography (US), among the conventional, spatial compound, and tissue-harmonic methods, exhibits the best performance for the detection of Implanon(R) with respect to generation of posterior acoustic shadowing (PAS). MATERIALS AND METHODS: A total of 21 patients, referred for localization of impalpable Implanon(R), underwent US, using the three modes with default settings (i.e., wide focal zone). Representative transverse images of the rods, according to each mode for all patients, were obtained. The resulting 63 images were reviewed by four observers. The observers provided a confidence score for the presence of PAS, using a five-point scale ranging from 1 (definitely absent) to 5 (definitely present), with scores of 4 or 5 for PAS being considered as detection. The average scores of PAS, obtained from the three different modes for each observer, were compared using one-way repeated measure ANOVA. The detection rates were compared using a weighted least square method. RESULTS: Statistically, the tissue harmonic mode was significantly superior to the other two modes, when comparing the average scores of PAS for all observers (p < 0.00-1). The detection rate was also highest for the tissue harmonic mode (p < 0.001). CONCLUSION: Tissue harmonic mode in uS appears to be the most suitable in detecting subdermal contraceptive implant rods.

The mammographic or physical evaluation of breast parenchymal abnormalities in the presence of radiopaque implants or silicone injections is difficult; mammography often fails to discriminate between breast cancer and a radiopaque dense breast. Although the sonographic evaluation of a palpable mass in an augmented breast may be impaired by the presence of posterior acoustic shadowing, the modality may be helpful in evaluating such masses, and dynamic contrast-enhanced MR imaging facilitates differentiation. FDG-PET is a possible alternative diagnostic tool for the evaluation of parenchymal lesions under these circumstances, but its drawbacks are its high cost and limited availability. The sensitivity and specificity of both FDG-PET and MRI can be improved by correlating their findings with those of radiological studies, and through an awareness of potential false-negative and false-positive causes.

PURPOSE: To evaluate the clinical and radiographic findings of localized foreign body (FB) granulomas onmammograms. MATERIALS AND METHODS: This study involved 13 patients with localized FB granulomas on mammograms;their history of mammoplasty or other plastic procedures was obtained by telephone interviews. Two radiologistsanalyzed the location and morphology of FB granulomas and the presence of associated linear densities orparenchymal distortion on mammograms. Four patients underwent ultrasonography. RESULTS: No patient had a historyof mammoplasty. All 13, however, had a history of plastic procedure, three to 22 (average, 12) years previously,as follows : foreign materials including silicone liquid and oil such as paraffin been injected into the anteriorneck area of nine patients, the infra-auricular area of two, and the nose of two. Multiple small, high-density,flocculent nodules representing FB granulomas were distributed bilaterally in nine patients; they were noted inthe upper inner portion of 11 of 26 breasts. In eight patients, mammograms showed linear opacities suggestingfibrosis. There was no calcification or parenchymal distortion. Though in three cases, the masses were palpable.Ultrasonography revealed several anechoic nodules with posterior enhancement in subcutaneous fatty layers, and inone, 0.2cc of oil droplet had been aspirated under ultrasonographic guidance. CONCLUSION: Localized FB granulomasof the breast could be caused by the migration of FB from cervicofacial areas. Mammography showed characteristicdistribution of upper inner portions, and the findings were similar to those of mild interstitial mammoplasty.
